GPS and I2C sensors issue #143

Open CodeWorksCZ opened 3 months ago

CodeWorksCZ commented 3 months ago

Hello, I have got a small PCB board which has GPS(BN220) connected and it works fine 

Second analog to digital sensor is not detected
Foreseen GPS type is Ublox (configured by oXs) :GPS is detected but has not (yet) a fix
Led color is inverted

There are also sensors connected to it BME280, MPU6050, XGZP, ADS1115.

They also work but as soon as I connect BN220 and power on oXs , serial monitor is clogged by these messages:

Write error for BMP280: -1 Write error ads1115 Write error for MPU6050 Write error for BMP280: -1 Write error ads1115Write error for MPU6050

It only happens when all sendors and gps are connected o oXs

My susspision falls on GPS handling which somehow breaks i2c bus

Have anyone encountered this behaviour?

Hello CodeWorksCZ,

Here is my "full house" configuration. Everything works , no problems. I think your RP2040 board have a power problem or you have a sensor or wiring problem. You must set TLM= for Telemetrie and PRI= for SBUS, with your configuration the RP2040 can`t work correctly.

CodeWorksCZ commented 3 months ago

Thanks Torsten for your answer. I need to dig deeper. I have also ordered another GPS module to see if the one I have is not faulty.

THis is a custom PCB i designed and this time I added MPU6050 but not as a GY board module but as on board components.

Previous version worked but did not have MPU and XGZP module.

I am glad that your "full house" works. At least I know that I have look at the hardware aspect.

My suspect looking to your hardware (the oxs stack) is that you rely too much on the LDO of the raspberry, The raspberry ldo only supports very low input voltage (5.5V) and very low current. Your stack may ask too much. I suggest you to add an additional LDO like AMS1117-3.3 to supply enough current not regarding INPUT voltage.

CodeWorksCZ commented 2 months ago

Thanks @romoloman. I though about that as well and I even tried to power up the GPS directly from 3.3V bread board and no luck.

I made a small test rig using POGO pins to test both PCB before soldering them together. I am sure I will crack it soon or later. In the future version I might add this LDO if i find some space on the board

romoloman commented 2 months ago

I also have designed my own board to host some sensor but I have choose a different approach from your: immagine immagine I do not have cell measuring but I have optical RPM sensor, current (using a WCS1500) and temperature, plus onboard variometer (MS5611) and GPS, but if you look to the board there is the LDO The board is designed to be used with different protocols. (that's why the solder jumper for sbus2) With this design i have no problem in powering up gps, sensors etc etc (AMS1117-3.3 can supply up to 800mA)

For the GPS i use this one: https://aliexpress.com/item/1005006460489847.html It's rated for 5V but works at 3.3v without troubles. It comes programmed at 115200 so need a reconfiguration in u-center to slow down to 38400.
