Hi,I am trying to use DMA to realize uncertain length uart message receiving on STM32H745i-DISCO board (on core CM7). My idea is to used IDLE interrupt and then disable the DMA_stream, get the NDTR register and abort the transfer to trigger the DMA T...
I want to get a two 16 bit values through two spi interface within 4µs . So I set the baudrate 18Mbits/s so that for 16bits it takes just < 1µs. Everything is working fine.But the problem is the overhead time between twice HAL_SPI_RECEIVE is nealry 8...
I just solved a bug in my software, and can't quite understand how it happened. My code is a built in hardware test for our board, and a bootloader, which communicates with a serial bus and downloads different compoents to different memories. One o...
Hello I have DMA ADC and store data in uint16_t bufferI need to copy these values to input buffer to arm_rfft_fast_f32 function;the function should also cast ushort to float void copy_adc_to_input(uint16_t * int_buff, float32_t * float_buff, uint16_t...
FLASH->ACR |= FLASH_ACR_PRFTBE; /* Flash 2 wait state */ FLASH->ACR &= (uint32_t)((uint32_t)~FLASH_ACR_LATENCY); FLASH->ACR |= (uint32_t)FLASH_ACR_LATENCY_2;
Hi, everyone,I have been struggling with an issue for sometime. Upon reception, occasionally, a Byte is received with an error in which the most significant bit is received as a '1'. For example, if 0x55 (0101 0101) is sent, 0xD5 (1101 0101) is rece...
I'm not having any time critical routines so I'm hoping of using all of the MCU's 1MB of RAM for data. As I understand from the RM, RAM is organized in a several banks. Can it be used as a continuous chunk of 1MB for data?
Hi, I am using NUCLEO-F302R8 EV-board. I want to configure the CAN as:use all 3 transmit mailboxes with different mailbox IDFiltering ID number for each mailbox Receive three complete message for each FIFO with filter ID numberBy following CAN settin...
i used stm32f031 as master & slave, NSS is alwasy low, connect MOSI and MISO. the master transmit datas successfull then changing the master direction to receive data( SPI->CR &=~SPI_CR1_BIDIOE), at the same time slave recv and try to transmit data...
Dear st team,What are the major changes in STM32F767BIT6 and STM32F777BIT6?is STM32F767BIT6 code works in STM32F777BIT6?
