I want the Nucleo board 303RE to act as a debugger for my external board. Two boards have an individual 3.3V supply so the ground has been made common. Other Hardware connections are below. Since CUBE IDE doesn't allow to flash Bin files using ST-LI...
I have tested the microcontroller with different boards and all have the same problem. I have noticed that the voltage across the NRST is 0V, which I think means that the microcontroller is damaged (There is no short circuit in the system). I have co...
I'm looking to connect a Waveshare e-Paper display to my STM32U5 discovery kit (B-U585I-IOT02A).On the Waveshare website (https://www.waveshare.com/wiki/7.8inch_e-Paper_HAT), they have a pinout for the SPI bus on a STM32F4 chip as follows:Connect to ...
Hi community.. I am working with mcu STM32F429 and SRAM with code IS42S16400J .I have developed a code for init and working with this sram and it was workingvoid SDRAM_Init(void) { volatile uint32_t ptr = 0; volatile uint32_t i = 0...
How is PB0/PC5 mapped as serial port pins?
here is the pcb tried adding a capacitor of 100nF to GND like it was suggested in the datasheet still nothing the only work around i found is if i fiddle with a jumper between NRST and groud sometimes start the mcu or by touching the top of it with m...
I have stm32F407 discovery board and I have downloaded and installed the ST_LINK USB driver on my laptop running window 10, but when I plug in the discovery board, the error message pops up saying the USB driver is not recognized, in the device manag...
Hi, I made a minimum CubeIDE project for a Nucleo-L4R5ZI. It clocks the RTC from LSE using the X2 quartz (NX3215SA-32.768kHz-EXS00A-MU00525) and outputs a 512Hz calibration signal on PC13. The output frequency is only ~492Hz which is a deviation of ~...
I am attempting to write software for a "Kakute F7", which is a flight controller with an STM32F745VG on it (the schematic is attached). Some good graphics and a diagram of this can be found here.I keep getting errors when connecting to the MCU over ...
Hello thereI was trying to debug my stm32h750 with an stlink-v3 mini. I'm currently working with an external flash as my code area. The bootloader and external loader worked before, but suddenly I can't load code on my external flash. Does anyone kno...
