OpenLog Qwiic not working with STM32F429 Nucleo 144 Board #5

Open patilakash opened 4 years ago

patilakash commented 4 years ago

I am trying to log the data from STM32F429 board to Qwiic logger through I2C port. Below is settings for I2C in STM32F429 Address Mode: 10Bit Clock Speed: 400K

Following commands are sent from STM32F429 board

  1. Sent Data as "Testing"
  2. Sent Register Address "13"
  3. Sent Register Address "10"
  4. Sent Register Address "17"

The I2C device ID used to communicate with Qwiic log is 42.

Please help me to solve the above issue. I have tested the Qwiic board with Arduino UNO and it is working.

@patilakash hmmm, looks like the problem might be that you're using 10 bit addressing. If I remember correctly, the OpenLog and other Qwiic devices use an 8-bit addressing scheme. Check out the following article
