I'm out before I even really got started...

Hopefully someone at STE cares enough to take this honest feedback on board...My project had to move from atmel to something with more performance.  I settled on STM32.The experience has been terrible due to sub-optimal documentation from STE, relyin...

Is HAL_I2C_GetState() required in polling IO mode?

I am using the HAL library with an STM32L07xx processor. To keep things simple, I have implemented master transfers on the I2C bus in the polling IO mode. Most of the time it seems to work, however once in a while a master transmit seems to get lost....

Resolved! STM32L4 FreeRTOS vs Bare metal performance

Hi, I have an STM32L4x6 processor.I'm reading data using ADC and DMA, and after the HAL_ADC_ConvCpltCallback, I process the data with a Fast Fourier Transform. Originally, in bare-metal, I had a flag in the main loop, and when the interrupt occurred,...
