Hello,In stm32cubemx generated code there is the following routine.void HAL_MspInit(void) { /* USER CODE BEGIN MspInit 0 */ /* USER CODE END MspInit 0 */ __HAL_RCC_SYSCFG_CLK_ENABLE(); HAL_NVIC_SetPriorityGrouping(NVIC_PRIORITYGROUP_4);...
Hi Guys!I am using "STM32F407G DISC1 Discovery Kit" and I want to read data from an external ADC (via SPI) and store it in a micro SD card (via SDIO). I'm going to order a micro SD slot (https://www.amazon.de/MYAMIA-Micro-SD-Kartenmodul-Reader-Interf...
Hi everyone!How can i use my MCU STM32F407IG like a PL2303 FTDI. Like basically how can i use my mcu as a usb to uart converter? I already worked with the usb device cdc example and i send data to uart tx everything is fine an working but somehow wha...
Hello, at this moment i'm investigating the possibilities of our current system and would like to know if the 2 Octo-spi peripherals can be used as legacy, normal SPI.
The code works if i enter in stop mode but not if i enter in under drive mode.I think i have to reinit something after stop mode but i dont find what.Here is the code :int main(void) { HAL_Init(); SystemClock_Config(); MX_GPIO_Init(); MX_ADC1...
Hi,I am working for an project with STM32L496 target board. When i tried building the project, i got the error saying,ERROR: L6406E : No Space in execution region with .ANY main.o(.bss).I am trying to use full SRAM memory present(320KB) for the globa...
hello! i am using stm32f429 mcu ,i want to add a sdram as the main RAM.My sdram detail informatin,512K Words x 16 Bits x 2 Banks.i donn't know how to connect the pin which connect to sdram and control the internal bank of sdram to the sdram.s...
Hello,I'm having a hard time debugging a hard fault I'm experiencing.The hard fault occurs in the handler of external interrupt. Here's it's code:extern "C" { void EXTI2_IRQHandler(void) { static uint32_t last_sample_time = 0; if (EXTI_GetITS...
How can i transmit data through usb fs without ftdi usb to uart converter?
Posted on July 04, 2018 at 22:56I am doing now small project with STM32F0. I would like to generate two PWM signals simultaneously using DMA. Everything is working fine if I am starting one of two PWM Generators. When I start two works only first on...
