Consult SDP810-500PA for the reasons for unsuccessful airspeed testing #93

Closed aepub closed 1 year ago

aepub commented 1 year ago

purchased an SDP810-500PA today, which uses a 5V voltage and is connected to the SDA and SCL of RP2040, including the previous MS5611 and MP6050. The SDA and SCL pins are connected to three sensors. Unfortunately, the remote control did not see the speed information, and I blew air into the airspeed tube, but there was no change. speed1 speed12 speed2 speed32 speed244

Today, I tested the MS4525D0 module and I am very excited that it has a display and will have corresponding changes; Unfortunately, SDP810-500 did not display anything, and the I2C address was also modified in config. h during compilation! 810-500-1

mstrens commented 1 year ago

It is strange that the SDP sensor is discovered (it means that it replies to his I2C address) but does not provide data.

I do not have such a sensor. So I wrote some code but I could not test it. As far I remember some user tried a sdp3X successfully but I am not sure about the SDP810.

In the oXs program, there are 2 main parts:

When the RP2040 is connected to a PC via the USB port, the PC can display some debug information and let you enter some commands (like you did when you selected the Exbus protocol). There are 2 commands that can help finding in which part there is an error.

Please make those tests. If the bug is in the first part, I could make a version with even more debug messages in order to find the bug.

mstrens commented 1 year ago

Just to be sure: the sdp can measure differential pressures. It means that the returned pressure value can be positive or negative. Only the positive values are used to calculate an airspeed (for negative values oXs return 0). Are you sure that you connected the sensor in the right way to the pitot tubes?

aepub commented 1 year ago

My sensor is connected to the pitot tube, and I tried to blow air into the pitot tube, but there was no data change. I happen to have an original JETI airspeed meter, and blowing air into it will cause airspeed to appear.

In order to install the SDP810-500A sensor, I specially designed a PCB, z I bought a CNC pitot tube.

mstrens commented 1 year ago

When you send the FVP command, did you get an airspeed value (other than 0) on the handset?

Without sending a command, did you try to invert your 2 tubes connecting the pitot and the sensor.

aepub commented 1 year ago

Screen at startup： open FVP： fvp FVN： fvn

mstrens commented 1 year ago

So the FVP values are transmitted. So the bug should be in the first part of the code.

Here a version 2.7.1 (not available on github) to check if oXs can read the data from the SDP. Use it with the RP2040 connected to the PC (via USB). Every 2 msec, oXs is supposed to read the SDP and if OK, it should (with this version) send to the PC a line with 3 values about the pressure (raw values); Could you make a copy/paste of some of those lines when blowing in the pitot tube to see what oXs get from the sensor.

Did you modify the I2C address of SDP810-500 when compiling the code? I found that the SDP810-500 sensor was not recognized in the serial monitor!

No, I forgot it. I will make a new version.

It is strange! oXs does not get an error when reading the sensor but the values are always 0 (on first 2 bytes)

Here a version (2.7.2) oXs.zip where I should read the 9 bytes provided by the sensor (pressure, temp, scale and crc). I removed the previous message and I inserted only one line of message with the data captured when the sensor is initialized. The line begins with "SDP first read:" and should contains 9 values.

On the hardware connection, SDP810-500 uses a 5V power supply, uses SDA and SCL interfaces with MS5611 and MP6050, and uses a 4.7K pull-up resistor to 3.3V. Should this be a problem?

mstrens commented 1 year ago

I presume that using 4.7K pull-up to 3.3V is ok. In theory using also a MS5611 and MP6050 should not be an issue. Still I saw a post on Rcgroups about a GY86 module that delivers no altitude. So I am not 100% sure.

With version 2.7.2 (or 2.7.3), oXs should, after a reset, generate a line starting with "SDP first read:" followed by 9 values. Do you get such a line? If yes, what are the 9 values? Note: it is just generated once (after each reset) during the setup of oXs.

If you can easily disconnect the MS5611+MP6050 from the I2C bus, you could also make a test without those components. If it is difficult to disconnect them, I could make a version of oXs where I do not try to read those addresses.

I just noticed that when you did not yet used a FVP of FVN command, the compensated VSpeed displayed on the handset seems abnormal (to high value). If you did not yet disconnected the MS5611, could you also display the uncompensated value of Vspeed (this one is calculated based only the MS5611) and should be close to 0 when the sensor does not move up/down.

My MS5611 and MP6050 are integrated on a PCB, making it difficult to disconnect them. Perhaps this PCB will not function properly!

Is it possible that my newly purchased SDP810-500 is damaged?

It is clear that when oXs tries to get data from the SDP, it get only 0. I do not understand why. There are no real errors detected on the I2C bus. When oXs sent commands, it checks that the I2C sensor replies with an ACK. That seems to be the case. This works because when we use a wrong I2C address, we get an error.

I can make change to oXs to see if I can read e.g. the type of SDP. This require specific commands I think. I will check the datasheet.

It would also be possible to test just the SDP alone if you could be able to connect it to another MCU board (e.g. an RP2040 zero or an arduino uno/pro mini/nano). Do you have such a board?

After using RP2040 zreo alone,

Command FVN, remote control display: Airspeed 0KM/H Comp Vspeed -1.67m/s

Command FVP, remote control displays: Airspeed 545KM/h Comp Vspeed 1.67m/s

Here a comment for a previous test you made: FV just after a clean boot (so before a FVP or FVN) gives the values that oXS get (calculates) from the sensors. Vspeed seems OK. So MS5611 is OK Airspeed has a very high value but this is the result of getting 0 in reply from the SDP during the initilization process.

At this stage, FVP and FVN commands does not help because the issue is not in the second part of the program (when data are transmitted)

About you test with a RP2040 zero alone: It seems it is the same issue.

I made a new 2.7.4 version (in attachement) where oXs tries to read the product identifier of the SDP. Just like previous version, there should be a one line message that begin with "SDP product first bytes:" generated during the initialization after each reboot.

at least with this test, the 9 values are not all 0. Still I suspect that those are not the expected values (does not seems to be the product ID given in the datasheet). So it could be that this is just the content of an un-intialized buffer. To clarify this, I made a version 2.7.5 where I prefill the buffer with special values before reading the SDP. Can you try this version and report the same lines as before oXs.zip

OK, I have installed version 2.75 and also executed the FV, FVP, and FVN commands! I still use RP2040 ZERO!

Thanks for testing. The values are the same as in previous tests. I presume they are really returned by the sensor because in 2.7.5 oXs pre-fill the buffer with other values.
The returned values are very strange. 19:21:15.869 -> SDP product first bytes: 0 0 81 2 F0 DA 0 0 0 19:21:15.947 -> SDP first read: 0 0 81 2 F0 DA 0 0 0 3rd value = "81" should be a CRC on the first 2 (= 0 0). 9th value = "0" should be a CRC on the 7 and 8 values (= 0 0). I did not yet checked how CRC is calculated but in any case, it is not normal having 2 different CRC (once 81 and once 0) for the same values (0 0).

At this stage, I do not understand. I will have to stop testing for today because I have to leave home. I will further think on the issue. We can continue to morrow if it is ok for you. Do you have an arduino board (uno, pro mini, nano) that could be used for testing a total different program just for SDP?

aepub commented 1 year ago

Okay, continue testing tomorrow, what I should be able to find is Arduino 328P!

mstrens commented 1 year ago

I checked CRC calculation. When we get 0 0 81 2 F0 DA 0 0 0, I noticed that: 81 is indeed the CRC of 0 0 DA is indeed the CRC of 2 F0 The last 0 is strange because it is not the CRC of the 0 0 before. I do not understand. It looks like the sensor reply only part of the expected data.

Furthermore, it is strange that the sensor provided the same reply when oXs requested the product ID and when oXs requested the pressure/temperature.

I made a version 2.7.6 where oXs

mstrens commented 1 year ago

If version 2.7.6 does not help, I suggest to make a test with another program. I found some arduino program made by sensirion (manufacturer of sdp8xx). Here is a link to this program https://github.com/Sensirion/arduino-i2c-sdp

The instructions are given in the link (in the readme section. Please note that you have first to install this program as a library. Then there is a second library to install (see the link under Dependancies" in the readme section). In Arduino IDE, I installed the package for the board RP2040. In menu "tools" + "board manager", there a several options for RP2040. I selected the package made by philhower. This package allows to select a board Waveshave RP2040-Zero. Once the board and the libraries are installed, it is possible to use the example provided by Sensirion (with menu "Files"+ "Example" + "Sesirion I2C SDP" + "ExempleUsage" I could not test it myself but I could at least compile it. Note: I do not know at this stage which GPIO pins are used for the I2C with this program. I suspect they are not the same as oXs. I can eventually look for this.

The program is supposed to display the product ID of your device and then the pressure and temperature. If it works, then the issue is in oXs and it makes sense to continue to search for a solution. If it does not work with this original sensirion program, then I presume your device is defect.

I think that default I2C pins for RP2040 in Arduino are:

The Arduino test results also seem to have issues! SDA = gpio 4 SCL = gpio 5 adr1 adr2 adr3

aepub commented 1 year ago

The I2C definition of RP2040 ZREO is: GP4- SDA; GP5- SCL; The address of SDP810 is 0X25, and none of the above should be a problem. Perhaps there is a defect in my module hardware, and I am trying to purchase a new one for retesting. It is estimated that it will take about 3-4 days to receive it! 2040

aepub commented 1 year ago

I'm really sorry, I just found out that my module is not SDP810-500PA, it's ADP810-500PA module. Perhaps the merchant gave me the wrong model, but I haven't noticed it yet! adp810

mstrens commented 1 year ago

This probably explains that oXs did not work. I just had a look at the ADP810 datasheet and even if it looks quite similar, it does not support all commands as SDP810.

If you want, it is probably possible to change oXs code in order to use ADP810 but performance will be less than with SDP810. It requires about 10ms minimum per pressure conversion while SDP requires only 500ms, calculates itself averages and does not require a new I2C command for each conversion. So ADP810 will probably give more noisy measurement but perhaps this is still acceptable.

Let me know if you want that I adapt oXs code to support ADP810.

aepub commented 1 year ago

I have repurchased SDP810-500PA, but ADP810 has already been used and welded to the PCB, so it cannot be returned. If this code can support more sensors, such as adding support for ADP810, I can test it after you modify the code, so that everyone may have more options. Thanks for your help！

aepub commented 1 year ago

Perhaps it is also possible to increase support for SOP-8 packaged sensors such as MPXV7002DP

mstrens commented 1 year ago

I made some changes in order to use an ADP810 (I hope). After a reboot, oXs should display a line beginning with "SDP first read" and 9 values. Those values should be different from all 0 or a sequence 0 1 2 3... You can test it with you standalone RP2040. You can also (with this stand alone device) send several FV commands (not FVP nor FVN). Airspeed should be present in the displayed values on pc with a value different from 0 if you blow on the pitot tube

If this works, you should get airspeed on the handset with you other rp2040

Blowing air into the pitot tube indicates that the remote control data has changed, indicating that it is already working. However, in static conditions (without blowing into the pitot tube), Airspeed will jump between -1Km/h and+2Km/H, while Comp Vspeed will jump between -1m/s and+2m/s. 31 32 33

mstrens commented 1 year ago

Airspeed sensor does not provide accurate value for low speed because the difference of pressure is very very small between 0 and 1km/h. When the airspeed increase (change e.g. from 30 to 31 km/h, the difference of pressure must be much higher and so can be better detected/measured by the airspeed sensor). Making many measurements and averaging can increase accuracy (and reduce noise). That is the reason why using a SDPxxx sensor should be better because it allows to get about 20 X more measurements per second.

Fluctuations in Vspeed are probably the result of a noisy airspeed signal. People using SDPxxx sensors did not get so big fluctuations (or at least I did not get claims) Perhaps is ADP not a good choice or I should have to calculate an average on more measurement but then the Vspeed will become much less reactive. Note: compensated Vspeed is based on 2 measurement : Vspeed+airspeed. To be sure that Vspeed does not fluctuate to much, you could perhaps also display Vspeed on your handset near the compensated airspeed.

oXs.zip It is not normal to get "Write error for MPU6050" when the MPU sensor has been detected. I think that you did not get this message with previous version (as old as 2.7.1). I now made a version 2.7.8 with a minor change about MPU6050 but I am not sure it will help.

aepub commented 1 year ago

Thank you very much for your efforts. The ADP810-500PA is now working perfectly, blowing air into the pitot tube, which can display a maximum speed value of 107KM/h. Looking forward to testing the newly purchased SDP810-500PA in a few days. Thank you again! 107

aepub commented 1 year ago

Hi, mstrens I have received the newly purchased SDP810-500PA, which is using main's 2.5.0 or test's 2.71-2.76. I cannot recognize SDP810-500PA!
