Hi, i come across a H7 code that use HAL_StatusTypeDef , could anyone kindly advise what does the HAL_StatusTypeDef do, whats HAL_OK means? what does ret != HAL_OK mean? and what does return HAL_OK means?HAL_StatusTypeDef spi_write(reg, *pData){ HAL...
Hi all, I have a problem which is bugging me as I can't figure out what im doing wrong. I am trying to read from ADC_IN4 but are reading wrong values. I should be reading apprx. 30000 ADC value but i am reading apprx. 7800. I think that this indica...
Hello,I keep getting an NMI fault when I attempt to read a variable with gdb (either with a mouseover on a variable in STM32CubeIDE or the print [var] command in gdb). I'm not seeing anything useful when I view the microprocessor registers after the ...
Hy,I am new by using nucleo board. I am evaluating the bootloader which runs fine for y first tests and I try to enlarge configuration capabilities. To focus on this goal I am looking for the registers map available with STM32L0 series.In the referen...
Hello,I am working on STM32F030R8T6 with HAL.We are trying to read ADC values from the 4 ADC channels and 5th channel as VREFINT.The ADC is configured in continuous DMA read by using:HAL_ADC_Start_DMA(&hadc, (uint32_t *)ADC_Buffer, 5);Our AVDD = 3.3 ...
Hi!I am looking into the possibility on using LPTIM1 to trigger a DMA transfer with no CPU interrupt. This timer is chosen because it can be clocked directly by the HSE clock input. In the datasheet of STM32H7B3 (DS13139 - Rev 8) table 4, it states t...
I am using F411 as the main controller of some DAC/ADC modules.I need to put MCU in stop mode to reduce its power consumption.I wonder whether or not I need to configure all the I2C, SPI, and UART interfaces when MCU wakes up from stop mode.

Hi! I'm currently trying to mount my sdcard via MSC/SDMMC and tinyUSB. It worked fine with RAM, could read and write, but I probably do the commands wrong for SD Card. Mounting with FatFS works fine, but I cannot get it to display any device on my dr...
I'm currently evaluating the STM32U5 series to connect to a camera via DCMI and store video (i.e., multiple frames/images). For now, I would like to keep things simple and also learn how the DCMI and DMA workflow is like. So, I'll keep this forum pos...
