I have a board with STM32F030K6 and an sensor wired on I2C. When using the sensor in polling mode (no interrupts) everything is working fine and i am able to read data and send it trough UART.
Problem starts when I want to use a timer to generate a delay, because sensor need 20-30 minutes to stabilize readings.
I am trying to use TIM14, which is independent timer, but when it is on, and counting, the I2C transaction fail and i gent an error response from the sensor.
If I disable the timer, everything is working fine.
Can anyone help?
