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...
I am using STM32H747I-DISCO board and got this error when I try to connect in STM32CubeProgrammer Error: No STM32 target found! If your product embeds Debug Authentication, please perform a discovery using Debug Authentication.Please anyone suggest h...
Hi I am a hardware design base person, it's been a while I wrote the code. I have one STM NUCLEO-F401RE board and one sht3x i2c sensor. I wonder how to make them working (at least print sensor information via UART serial port). I see some source co...
Hi all, im using STM37H74x evaluation board and i managed to get most of it working (PWM, DAC etc..)but when i try using the ADC i get strange input, putting the configuration aside, this is what my main looks like below.im using ADC1 ch6, according ...
Hi guys, I want to wake up my MCU every 10 sec. And I had to write some code as follows: if(__HAL_PWR_GET_FLAG(PWR_FLAG_SB) != RESET) { __HAL_PWR_CLEAR_FLAG(PWR_FLAG_SB); sprintf((char*)uartBuf, "wakeup from standby\n"); HAL...
