i am using stm32h723zg nucleo board, I'm using adc's direct channe, There are 2 different analog channel definition processes for the direct channel.what is the difference between the two.A-)LL_SYSCFG_OpenAnalogSwitch(LL_SYSCFG_ANALOG_SWITCH_PC2|LL_...
Hi All,I have a waveform generator which uses TIM4 to trigger the DACs and they trigger DMA to transfer 32-bit words to the DACs (concurrently).I am using the DMA double buffer mode. So I have two source pointers, which are supposed to get flipped ea...
I've configured SWDCLK as UART_Tx in the initialization section. Everything runs fine but after running the system for a long time UART_Tx pin goes low all of a sudden and communication stops. The Tx pin remains low even if I reset the MCU. If I repr...
Hello,I have some problem with enable idle line interrupt in STM32H723. Previously i tested on stm32f7 and worked great. I use only HAL function. Below i show my code responsible for idle line on F7, the same code dont work on H7.Does anyone have an ...
I've created a single pulse that executes for about 150ms. When it's complete I was expecting HAL_TIM_PWM_PulseFinishedCallback() to be called, however, it never is.Doing this:if (HAL_TIM_OnePulse_Start(&htim1, TIM_CHANNEL_1) != HAL_OK) { /* Starti...
Hi there,I want to do a printf redirected to a Tera Term using the USART2 on the STM32F407G-Disc1, but it doesn't print while the same code works on the NUCLEO-F401RE. I found this instruction in the user manual UM1472. Does it mean that I have to u...
Hi guys,I am struggling for a few days with the MAX31850K (Cold-Junction Compensated, 1-Wire Thermocouple-to-Digital Converters) so I was hoping that some of you might have experienced the same issue.The chip is soldered on my custom PCB (I am not us...
Hi to all,I'm trying to write my own I2C class, but SDA seems not willing to collaborate.Here is pins configuration:#define I2C1_SCL 8 // PB8#define I2C1_SDA 9 // PB9MYI2C::MYI2C(){ if(!(RCC->AHBENR & RCC_AHBENR_GPIOBEN)) RCC->AHBENR ...
I am working with stm32H743 MCU, sometimes when I add a function, its calling caused a hard fault, when I move the function to another place in the code, the fault is resolved.What can be the reason?
I have a strange issue. I use printf function in a uart port for print some variables that I use in my code. This works perfectly in cortex m4, but now in cortex m0, the variable printed show me 0, in the next code:uint8_t flash_ext_init(void){ ui...
