Good morning, I am currently working on the nuclei H755 ziq. it says on the data sheet and on stm32ide that it has two FDCANS. however, I have only found in the schematics one tx and one rx port. how do I know if they are connected to FDCAN 1 or FDCA...
Hi,Facing an issue on the STM32L4A6ZG. Trying to transmit 255 bytes through the SPI DMA at 12MHz. Correct data transmitted out on the MOSI till byte number 203, then the next 4 bytes are transmitted incorrectly and the 209th byte onwards it's correct...
Is the pull down resistors on PA7 and PC1 necessary or can I skip these? (These pins are SPI2 MOSI) The reason why I ask is because I need to use the ADC functionality of these pins, but with the pull down resistors it's messing up my ADC readings, s...
I have some strage problems trying to access all 32kB FLASH on this chip.If I run a program in the first 16kB of the flash space, it runs perfectly and I can read and write the full 32kB of flash. Reading and writing the full flash is also possible f...
I am trying to route the HSI clock to an external port of the board and so far I have got this code: #define RCC_BASE_ADDR 0x40021000UL #define RCC_CFGR_OFFSET 0x04UL #define RCC_CFGR_ADDR (RCC_BASE_ADDR + RCC_CFGR_OFFSET) int main(void) { uint32_t...
Hello,I'm a newbie ,and I'm facing some issues.. I used two NUCLEO-H503RB boards, one as a controller and the other as a target. I connected them as shown below. . And I tried them with the Example code "I3C_Controller_Private_Command_IT & I3C_Targe...
As per my understanding of stm32 uart driver interrupt code the usual process for receive interrupt is,1. HAL_UART_Receive_IT:It checks if huart->RxState is HAL_UART_STATE_READY.If true, it sets huart->RxState to HAL_UART_STATE_BUSY_RX.2. When Data i...
Hello everyone,I’m facing an issue described in this link: My STM32 device is overheating and has malfunctioned.My STM32G070CBT MCU has been damaged, specifically from the PC6 pin, which wasn’t in use. Unfortunately, the pin is connected to another d...
Hi, We have an application on STM32G491 where need to detect a button press after the device was switched off for some minutes. To implement this, we connect a standard capacitor (100 µF) to Vbat pin, Activate battery charging to load the capacitor, ...
Hello, is there any Application note or guide for how to use ITCM and DTCM on STM32H7 Series?
