Hi Team I wanted to measure the power consumed by the device i.e. STM32H7B3I-DK while running any application like taskIs there any api that helps me to measure this can anyone help on finding a way to do this
I want to build a system based on the STM32H735ZGT6. The data sheet (page 115) refers to application note AN5419 "Getting started with STM32H723/733, STM32H725/735 and STM32H730 Value Line hardware development". However, I cannot find it.
Hello,I have questions about handling multiple UART ports.Connections are;PC <--USB VCP--> STM32(1) <--UART1--> STM32(2) <--UART2--> Target deviceTwo STM32 are both L412K series,And I wanna make a application which forwards data to the target device...
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?
