I'm having some trouble getting an accurate PWM signal from my H743ZI Nucleo board (MB1364C). It is off by about 1%. I am not using an external crystal, I am using the MCO signal from the F723 chip on the same board. Am I just misconfiguring somethin...
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...
