Hi All, I am using the STM32H723 device and have used the HAL functions and they work but I find the SysTick or any timebase interrupts my code. Timing is critical; if the data from the serial port is interrupted by the SysTick interrupt, I lose data...
Hi, Alli'm using stm32G070CBT6, i have some problem with low layer usart interrupt.the MCU seems always hang when received usart byte. Has anyone here experienced something similar?how to solved this case. thanks
Hi, I have use MX to generate code for this timer. The generated code is as follows: static void MX_TIM2_Init(void){ /* USER CODE BEGIN TIM2_Init 0 */ /* USER CODE END TIM2_Init 0 */ TIM_ClockConfigTypeDef sClockSourceConfig = {0};TIM_MasterConfigTy...
Hello,I'm having weird problems with code crashing, perhaps related to how I have IRAM1/IRAM2 set up in my project:Looking in the reference manual, I see that the SRAM starting at 0x2000_0000 is the DTCM_RAM on TCM interface (data RAM?), the SRAM sta...
Hi,Currently, we are facing an accuracy problem when using the built-in DAC on the STM32F407 (with buffer enabled). As the built-in reference voltage measured 2.0005V, we set the DOR to 0x800, expecting to get 1.25V on the DAC output. However, we act...
The FDCAN loopback test of G474 can enter the receive interrupt, but normally the two devices communicate with each other, and when one of the devices is used to debug, it is found that the interrupt cannot be entered。
Hello, I have several boards to design where we can fit everything into the STM32F103. We don't need USB, CAN, or Ethernet. However, the price for the '103 isn't that different from the '403 or the '722. So for a brand new project which family would ...
Hi,I'm trying to run dual QSPI Flash with my own design STM32H750XBH6. Flashes are 256 mbit MX25L25645. Single mode 32 mb flash read, write and boot succesfully. However, when I switch to dual chip mode, i get a write error (constant 0XFF) on the 2...
Hello, I've used TIM2 to count to 100000 every second. With this i hope to make a very accurate millisecond timer. I can see the counter succesfully going to 1s and then i reset it manually using the RTC interrupt.Now i want to use an output compare ...
Hello everyone, we want to read the value from the temperature sensor with ADC using the stm32f431kbu6 microprocessor. We use the code mentioned below. #define TS_CAL_1 (*((uint16_t*)0x1FFF75A8)#define TS_CAL_2 (*((uint16_t*)0x1FFF75CA) float mcuTemp...
