Hello, a page erase on STM32F103 with 1k size usually takes some 22 ms with busywait. Now I started the erase and instead of waiting I reset the STM after 1 ms after the start instruction using a output pin and a second micro. The strange thing is th...
I am trying to make the ADC and the DMA work in the STM32G431 without success. I can make the ADC work but the DMA transaction is not triggered. This is my code://****************************************************************************** void AD...
HiWe are facing a problem while trying to read data out of QSPI flash in memory mapped mode shortly after programming a page in DMA mode. We see that the read data is corrupted / unexpected altough flash hast he correct data. Our steps to reproduce t...
I would like more information regarding errata 2.2.18 for STM32H750VB Silicon Rev V, from document DM00399555, which reads:"When a DAC output is connected only to an on-chip peripheral, the corresponding GPIO is expected to be available as an output ...
Hi all,I'm trying to use a example which works and compile correctly on stm32f103 (cortex-m3) family.Now i want to use this example on stm32f030c8t6 ,but there is erorr on line 6:BOOL xFCPortSerialGetByte( CHAR * pucByte ) { /* Return the byte in t...
Hello all,I am using NUCLEO-F446RE board.I am looking for some way to find how many bytes of data is received over UART which we want to read using HAL_UART_Read API.Normally, we will know what is the incoming data. So, depending on that we Read thos...
Hello,I have a problem,i wrote this program but it dosen't work.It doesn't read its rx pin.Can you help me pls ???

hi hope have good dayi need to buffer data for save on every 1ms for serial and spi i use dma to receive datafor example hal_uart_receviveDMA on this function must set buffer size ...i test one example :50Hz send to mcu data each time 1000 and 1001 ...
Hello, I am working on SDMMC ReadBlock function using DMA with peripheral flow control enabled. When I try to transfer 512 Bytes block from the SD Card, I have last 3 DWORDs "mising" (CNDTR is 0xFF82 instead of expected 0xFF00). These DWORDs are tra...
