How to realize single core reset in stm32h745?
For example: M7 program opens the watchdog, when the program enters hardfault, only M7 program is reset without affecting the normal operation of M4.
STM32F207 RAM Execution
Hello,I'm developing on an STM32F207 and I would like to know what the procedure to execute code from RAM is?I need to modify a couple of sectors of the internal Flash but the F207 does not have banked memory so I would need to execute the flash eras...
LSI Clock compensation issue, technical datas ?
Hello,I'm working on a low cost design which use LSI Clock. I need to compensate RC osc. deviation as best as possible.I didn't find technical datas about this. Is there any documents with precise datas on deviations according Temp. for examples and ...
STM32L412 interrupt latency and jitter
I am running STM32L412 on 48MHz MSI, Timer 2 is configured in One-Pulse mode to output a 2ms Pulse. This is done by setting Timer 2 in PWM mode and with a prescaler of 47, ARR = 1999 and CCR = 1, Polarity=LOWAn interrupt is generated on update Event,...
LPUART1 Issue
Hi,I am learning how to use LPUART1 on the Nucleo-64 (STM32L433RCT6P) to generate messages on the COM4 port of my Windows 10 laptop. A "Hello World\r\n" message should be printed every time the blue User Button on the board gets pressed. Here are the...
Resolved! I want to know if I have this right for the STM32 with the HAL library. I have this working on an Atmega. And Arduino has also a lot more examples to find then STM. So due lack of examples I have wrote this.
1) Set output high2) When input is low wait till it is high3) When input is high read 6 characters4) When having read 6 characters then output low and return (or leave while loop)void Get_Instruction(){ HAL_GPIO_WritePin(GPIOA, GPIO_PIN_12, GPI...
Can I configure 1 micro sec delay through systick timer on STM32F373RCT6?
I am using STM32F373RCT6 on customm board. By default systick timer is configured for 1ms but I want to configure for 1micro second. Is it possible? HCLK is 28Mhz and SYS clock is 28MHz.
Programming Flash without HAL
Hello, I am trying to make my own bootloader for STM32H743AIIx. Unluckly, I can't erase or program flash memory by my code. I unlock both of banks and see LOCK in FLASH_CR goes down. I put PG to up and write data until EOP flag is set. Despite the fa...
Problem with I2S TX / RX Circular DMA on STM32H743ZI2 board
I have a problem with DMA on this board that was not present on an F407 using code generated by Cube.I2S2 has been configured as master half duplex and IS23 as slave half duplex (fed clock and WS of I2S2). The plan was to have a MEMS microphone on th...
