I have successfully configured USB On-The-Go (OTG) on an STM32 microcontroller to support both Abstract Control Model (ACM) and Human Interface Device (HID) protocols. I utilized the stm32_usbotg_eth_config.sh script as a reference, and the setup is...
I need to measure the time it takes for a component to reach a certain voltage, read out with the ADC. So far I have been measuring in microseconds but it turned out that that is not precise enough.I found the following code to measure time on Stacko...

Dear Community,I've got STM32H730 with ext Flash on OCTOSPI2 and ext RAM (s70kl1283) on OCTOSPI1.I call SCB_EnableICache(); and SCB_EnableDCache(); early in main, then I configure the MPU.I've got no problems executing code from ext Flash/OCTOSPI2 ...
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...
