When attempting to write to an SD card with HAL_SD_WriteBlocks_DMA() I expect the data to be written and then the card status to change to HAL_SD_CARD_TRANSFER. However, that never happens.Here's a short snippet of code I am using (this is pretty muc...
Hello,I would like to use a microcontroller which keeps around 600x800 pixel one image comes from a camera and compresses it. They are very simple functions. It needs at least 600 kB RAM to keep one image. However I could not find a low-cost microcon...
I'm using an STM32G431 using differential outputs on channel 1. On the scope, my deadtime is set where the channels overlap instead of having deadtime:channel1 ___-------___ ------__------- channel1_nHow can I reverse the direction of the deadtime?He...
i use nucleo - f410RB board , i want to configure 16 adc channel continuous conversion and continuous scan mode, we use cube mx for adc dma code generation , but generated code not working , so please help me how to configure adc in dma mode so ad...
Hello,I am using STM32F446RE controller to communicate with TLC2578 old ADC converter through SPI communication.To initialize the ADC first CS should be LOW and 16 clock - SCLK cycles need to issued.How to start the SPI clock without data transfer.Wi...
Hi, I wonder in which state are the GPIO lines of STM32F407VG BEFORE loading program to flash memory.Thanks :)
Hi all!I got something new for you. We have a pcb with an STM32f446re chip on it. For stability reason, we put an 20Mhz external clock on it, but the problem is, we are still running on 16Mhz (measured it with a toggled gpio on the oscilloscope.) The...
Hi,I want to use an STM32H743 for sampling one TIM.CNT and one ADC channel synchronously and store the data of both peripherals in array buf_adc[5000] and buf_timcnt[5000]. Therefore I want to use the DMAMUX request generation and use LPTIM2 as trigg...
