I referred to the example of 1.16.1 of F746G.The contents of MPU_Config() and System Clock_Config() have been copied. Ping test failed after applying rtOS (Stack Size = 256) and LWIP.The example is ping test, so there is no problem with the configura...
I have looked into the AN2606 guide and found that the MCU I am interested in says the bootloader is accessed by:Pattern 10 Boot(pin) = 0 or 1 BOOT_ADD0 or BOOT_ADD1(optionbyte) = 0x1FF0 A requirement that I have for my product is that if the device ...
I have two signals, one I would like to output for the first 950 ms of every second and then a second signal that I would like to output at a variable start time of each second. I included my code (the delay function does not work) for reference if ...
According to the overview it is possible to get up to 16 kB of flash memory. However I can't find a reference to this.
Hi everyone!I'm using a nucleo H755 boardI'm basically trying to debug my code from RAM. I already set the linker to use the autogenerated ld file (STM32H755ZITX_RAM.ld). When I try to debug, the application initializes, however It does not go beyon...
Hi,I want to use the ETR to count pulses and set a second timer, so every ... seconds the value from the ETR counter is red and renewed like discribed in this ExampleSTM32 Frequency Counter – LAB10 https://deepbluembedded.com/stm32-counter-mode-examp...
I'm trying to send data via USART to a serial monitor (i'm following a course) but i can't see it's receiving the data, the course is creating its own library manipulating registers.void UART2_WRITE(int ch); int main(void) { //enable clock to g...
Trying to synchronize in time three different STM32F446RE MCUs. I first tried to look how internal oscillators drift compared to each others.The datasheet says that the precision of the oscillations are of 500ppm (parts per million). So every 1000000...
Hello,I'm trying to implement a UART DMA data transfer in STM32F429. I face the following problem.I'm using custom-made Python to receive and transmit data over the serial port. I am sending an unknown number of bytes from my computer to MCU. So, I'm...
