大家都係用STM32CubeMX，所以Gen出黎嘅Code無太大分別。計功能肯定係STM32CubeMX強，第一佢有一個生成器可以生成粒MCU所有Setting，而PlatformIO係純Code，所以好考驗老師嘅功力，但係純Code有純Code嘅好處，就係學生可以更了解第一句代碼點影響粒MCU，會更有利於教學。STM32CubeIDE會要求你將啲Code寫係comment與comment之間，睇上去好亂，而PlatformIO無呢回事，啲Code睇上去好Clean。PlatformIO最大賣點係源於VSCODE所以有Github Copilot，我之前用STM32CubeIDE同VSCode開住同一個project，github copilot一邊gen我一邊改，我就無問題。但作為學生會好麻煩。 2025/08/24

My STM32 is bricked (can't run anything in STM32CubeIDE) because my main loop has no sleep, after i add it back, my STM32 can run many times in STM32CubeIDE. To recover my weact blackpill, i use "while true; do st-flash erase; sleep 1; done" to keep running the st-flash command, I found out pressing the […] 2025/08/04

With HSE = 25 MHz, the PLL configuration must satisfy: Let’s try the main PLL: Since PLL_Q must be an integer (4-15), 48 MHz USB is not possible with VCO = 200 MHz: To get exactly 48 MHz: Since SYSCLK cannot exceed 100 MHz, VCO = 192 MHz (SYSCLK = 96 MHz, USB = 48 […] 2025/08/03

In short, you need to build libsigrok then sigrok-cli Step 1: Add your device to Makefile.am Step 2: in configure.ac Step 3: Create /src/hardware/quantr folder add api.c, protocol.c and protocol.h api.c: protocol.c: protocol.h: Step 4: Build libsigrok Step 5: Build sigrok-cli Step 6: Test Then test it by "sigrok-cli -L", you should able to see […] 2025/08/03

Trying to build a logic analyzer prototype, today i am using weact black pill board. I am using interrupt to fire the DMA and get the pins values, then use virtual com port to transfer it to PC, so far it works 2025/08/02

Unlike nucleo to user serial port via usb by just enabling the uart. We have to enable VCP in weact H750 board. Reference: https://blog.csdn.net/Naisu_kun/article/details/118192032 2025/08/01
