The STM32F303RBT6 ADC2_IN3(PIN PA6) is connect to GND .When the pin PC4 set high,the ADC_IN3 read a abnormal data 0x70. When the pin PC4 set low,the ADC_IN3 read a normal data 0x00. Which the PC4 set high,is affect theADC2_IN3 sa...
Hello,I have a doubt about the amount of SRAM available on the STM32H7B3.In the datasheet it is indicated 1184kB (setion embedded SRAM), but the linker script indicates 1024kB.In the datasheet, there is not much detail on this.My goal is to use for a...
Hello. I am looking a way to read values from multiple channels of ADC module of a L031K6 MCU. Following an example in youtube I tried to use interrupt method. In the video he uses a F051R8Tx MCU. I develop code in STM32CubeIDE and tried the same ADC...
Is there a way to reset the timer (TIM4,3) via interrupt pin without using the interrupt handler/vector table?
Greetings,I am dealing with a STM32H743ZI MCU and many of its embedded peripherals, the board is a NUCLEO H743ZI2I encounter a strange behaviour regarding SPI configuration, for SPI 1 the MOSI pinout works as expected, but for SPI 3 and SPI 4 the MOS...
I am using STM32H743 nucleo board for the purposes mentioned below. I create the project using Cubemx version 5.3.0 and STM firmware is 1.6.0* Creating TTL Output signals* Reading TTL Input Signals*UART-DMA Receive&Transmit*PWM (100us PW, 1ms Period)...
So I'm back to the silly problem where the HAL misconfigures the default HSI calibration when I flash the same firmware to an STM32H743ZI that works on a ZI2, and vice versa: That is the HSI clock is off by 4% (see these questions https://community.s...
Hi!When I turn on the USB power on the Nucleo Board F401RE. I assume that the UART will work perfectly and be able to recieve data from the PC...but no.I need to press the black reset button directly after I have turn on the power to the Nucleo Board...
If I set the RTC (on a STM32F091) to Feb 28th 11pm, I can see that the RTC is correctly set. I can watch the RTC increase each second. However, when Feb 29th, 12:00 am is reached, the calendar date is changed to March 1, 2020; it skips Feb 29th. T...
