I wrote I2S Loop back test program. I2S2 as Master Transfer mode and I2S3 as Slave Receive mode. (Proto for ADC in and DAC out.)It works OK when 16bit in 16bit frame. However, in 24 bit in 32bit frame, DMA pointer etc. are corrupted.With step-by-ste...
Hello all,I want to disable the timer interrupt in the IRQ Handler and then enable again in the main loop. However the interrupt is triggered nearly immediately after I re-enable the interrupt (setting the UIE bit). I attached my code below. If I dis...
I've been trying to use the TIM2_CH1 function for PA15 but without success on a Nucleo-L073RZ. This function works OK on pins PA0 and PA5. Also PA15 works if set in GPIO output mode.Errata document does not state anything about this pin.Could you con...
I have an STM32H747i-Disco board and looking at the ADC example (which I have compiled and ran successfully)The example uses channel 18 and GPIO PA0_4 as both master and slave ADC inputs.I would like to use PA0_C and PA1_C as the two ADC inputs but I...
Hi,I'm attaching a picture of my clock configuration and Logic Analyzer (Saleae Logic Pro 8) so it is easier to see what I'm doing.I have set the SDMMC clock divide factor to 1 in the configuration tab, which should produce a divide factor of 2 in th...
Hi,Using STM32G474RE board (Nucleo-64). I have tried a lot of different things to configure VREFBUF and none of them have any effect.I'm outputting two voltages on DAC1 at 75% scale and 25% scale and they are always relative to approx 3.25V (which is...
Hi I am tryingthe spi dma example for stmH7 nucleo board, it is always takes me to the SPI_DMAAbortOnError function, and it looks like it is because it gives HAL_SPI_ERROR_UDR, any idea what could have caused it? For my master I am using 1Mbps clock ...
Hello, I am using an STM32L432KCU and I trying to use the TIM2_CH1 output as a re-triggerable output with TIM2 ETR input connected to COMP1_Output.The configuration done by STM32CubeIDE (version 1.3.0, build 5720_20200220_1053 (UTC)) is the following...
