Few things need to be care and different then STM32F411CEU6 Gitlab source 2025/07/23

I changed the clock to maximum 480Mhz, after I F5 for the first time, I unable to burn any program to it again. To solve this, press both reset and boot buttons on the board, click F5 in STM32CubeIDE, then release reset button (still hold the bott button). It will successfully burn the program again.

I got this error is i change "MODEL=atmega328p" to "MODEL=atmega328pb" in my makefile. Github copilot said the error occurs because the ATmega328PB has two TWI (I2C) modules, and its I/O register naming is different from the ATmega328P. Specifically, the ATmega328PB splits some port definitions (like DDRC, PORTC) into two sets (for PORTC and PORTD, etc.), […] 2025/07/22

Thinking how to build a logic analyzer using STM32. This example keep transfer the value of GPIO A to memory then fire interrupt using DMA. It will toggle PC0 for every complete transfer in my Nucleo L476RG board, I use oscilloscope to test, around 93KHZ 2025/07/21

All device pins should be connected to the same pins on the ESP32 board except the CS (chip select) pin. 2025/07/10

My old Ender 3 Pro, give 0.3mm X-Y Hole compensation, now no need polishing, I can plug them into another. Two filament print from two different nozzle temperature, same perfect. 2025/07/04

Step 1: create Dockerfile Step 2: Build the image docker build -t xclock-ubuntu . Step 3: Set XQuartz and restart it Step 4: Run "xhost + 127.0.0.1", and this "xhost +localhost" wont work Step 5: Run Another way 2025/07/01
