Values not stable on Warm Start

[afnan]

Hi, Hope you are fine. I found your board very well designed and easy to work with. However I am unable to get stable readings on warm start. Everything goes well on No Warm start and calibration goes well and i press 1 to save settings. However after rebot it seems that it does not remember any setting and goes out of whack. Readings for both Yaw, Pitch and Roll would keep on changing with more than 10Deg difference.

I am using ESP8266 and only change I made was I excluded #include <i2c_t3.h> and used#include <Wire.h> and modified similar things which were causing error in regards to this.

Thanks

Hi Afnan,

Likely you don't have the latest warm start sketch. I will ask Greg to see if he can help here.

Greg, can you give Afnan the latest USFS sketch with warm start capability lease?

Hi Afnan,

Give this one a try; it should work with ESP82XX as well with the right I2C library/call…

Best,

Greg

Thank you for sending the new code. It works fine, however I have seen that frequency of fail startup has increased. Do you know what is the reason for following ? any info on helping understand would be great. Thanks

The first error is common if there is not enough power available for the ESP8266. The second if there is a bad connection on the I2C lines, like no 3V3 power to the board.

I suspect in both cases, your connections are not robust.

Well everything works fine on first startup i.e when plugged into laptop. those two errors occur when i press reset button on node mcu. Probably they take some time in restarting. First error happens if i put i2c scan routine after connection to wifi hotspot and second occurs if I place it in very start of setup function. Probably it has something to do with power rise or something.

However following is the code where it takes time. Disabling wdt on esp will make it stay in following loop forever

 while (!(param_xfer == 0x4A))
  {
    param_xfer = readByte(EM7180_ADDRESS, EM7180_ParamAcknowledge);   
  }

[kriswiner]

Perhaps it is the ESP8266 board you are using?
