stm32f730 , Quad SPI ,i used to communicate to a device ,need 3bits data width. but how to configure the data shift out on the rising edge of clk and sample the falling edge . like the Stand SPI , we can set CPOL to '0' or '1'?if not to do , pls ...
HI ,My question is STM32L4 goto sleep (STOP2 mode). I found ADC function is not working when MCU wakup.If not goto sleep ADC is working well.
Hello,I'm having fun with hrtim configuration on STM32G4.To prevent to broke my device, I implement a faults management. I have also an external event that disable output (delayed idle mode), which can be reactivated by software when external event d...
Hi, i have read many guides about remapping sdram to 0x60000000 address range or setting up MPU to solve unaligned access exception. The exception is not a problem for me. The referce manual states that FMC peripheral does not support unaligned read ...
One of our project has problem, not easy to find, because of nonregularity of occuring in unknow part of code (it hasnt been reproduced in controlled way). I would like to write macro, that will replace every call of problematic part of code (which i...
I'm looking for advice on connecting 25 PDM microphones to an STM32H7. This seems possible from the RM, taking advantage of 4x SAI peripherals, each supporting up to 8 mics. However, when checking avail User Manual pins on several H7 variants, they ...
I'm using STM32L476 MCU.I config DMA Setting for USART. And I use HAL_UART_Receive_DMA in main.cIf I received data, test_count always increase two.void DMA1_Channel6_IRQHandler(void){ /* USER CODE BEGIN DMA1_Channel6_IRQn 0 */ test_count ++; /* USER...
What is the difference between LPUART and UART?. As far as i read there is no difference to use LPUART and normal one(except power consumption ofc). If I change my UART channel to LPUART, will be any difference? Will be the LP ones DMA usage differ ...
