Resolved! HardFault in etharp_raw with LwIP and NUCLEO-H723ZG
I'm quite new to STM32, and I'm trying to get LwIP up and running on my NUCLEO-H723ZG. No matter what I've tried so far, my board has always goes into HardFault, specifically during MX_LWIP_Init(), when the HAL calls etharp_raw(). Here is the full ca...

Hello,I'm facing a problem with a master timer and slave timer on Nucleo-STM32H723ZGT6U. To better understand my issue, I will present you my project.Project presentationMy aim is to make two PWM signals like this :The red signal is named "synchro ar...
Resolved! STM32F407 pulls up pins when debugging
Hello people, i am making a project using STM32F407VG and i am using a timer that drives a laser. The problem is, when debugging STM is probably pulling couple of its pins to High state before i start F8 (between pressing the 'Debug' button and F8 to...
Resolved! verification scenario to assure that data from adc is transmitted correctly through uart
so my project consists of : exploiting the serial communication to send the conversion data from ADC1 Channel 1 in ASCII format and considering a verification scenario for the program's functionality.about the verification scenario i visualize it in ...

when i downloaded the code from cube ide and then try to visualize it with putty it works perfectly but when i moved the project to keil and then download it from there i didn't got the same result ascii is stuck at number 8 and it's not showing the ...
Resolved! STM32G431: No FDCAN interrupts
I have two STM32 micros connected via CAN transceivers. The sending unit is transmitting without issue, as evidenced by measuring both the CANH/CANL bus wires, as well as the CAN_RX/CAN_TX logical wires on the transmitter. I did have to slow the bu...
