Posted on January 09, 2017 at 13:28Hello all,I have read through all contributions (e.g., https://community.st.com/0D50X00009XkdjTSAR) and cubemx (1.5.0) examples I found but did not find a working solution. Timer triggered, single channel sampling ...

Posted on December 01, 2016 at 11:45Hi, I found that a uart (standard configuration RX/TX, no flow ctrl) may receive some (wrong) symbols in polling mode but there is no interrupt at all in interrupt mode. Both mechanisms, of course, work fine if co...

Hi TDK,I just see that the AN5617 you referenced explicitly recommends DMA/MDMA in section 3.3.3.Would you say that the cpu offloading effect is not very relevant in the dual core architecture given?Is there any example code that shows how such an MD...

Posted on January 18, 2017 at 13:56The problem seems to be solved:1) I had to start the ADCs in a correct sequence (adc3 and adc2 before adc1) in main() such as if (HAL_ADC_Start(&adcHdl3) != HAL_OK) Error_Handler(SOME_ERROR); if (HAL_ADC_S...

Posted on January 10, 2017 at 09:24This what happens: depending on the baudrate RXNE is sometimes set, sometimes not - which is probably due to framing errors. In the latter case, there is no interrupt. Clive, thanks for your hint.
