I download the STM32CubeF1 package and compiled the stemwin hello world demo. It is works fine, everything is ok, but I turn on the i2c1 with HAL driver and connect to LM75 temperature sensor. If I put the i2c1 init and temp read after the gui init, its not working. I2c1 is stopped, and exit with timeout everytime. If I put the i2c1 init and temp read before the gui init, its work fine, the result is ok, but If I put the temp read after the gui init, is not working. The i2c2 is working everytime and everywhere.
My hardware is ok, i2c1 is working without stemwin everytime.
I was unable to find anything useful by googling. Thanks in advance for any help and sorry for my english
