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...
Hello, I have a evaluation Broad STM32L552E-EVAL, I need to have a power supply 3.3V on this card to supply another card, do you know where I can find this power supply ? Thank you for your helps Regards
