了解Pulseview Logic Analyze背後運作

2026-01-10 272

因為想知道Pulseview背後運作原理來，又想為cpu開發加入一啲特別嘅功能，所以決定用STM32自己搞一隻logic analyzer，雖然STM32用來搞不會很高速，但足了之解其原理，之後再用FPGA搞會非常容易 Pulseview是logic analyzer的GUI界面，sigrok-cli是命令行模式，兩者是呼叫一個名為libsigrok的庫去和你的logic analyzer溝通。至於libsigrok用什麼去和你的logic analyzer溝運，這個是你個人意願，因為stm32可以自己變成uart device所以就當它是uart去溝通最容易。你的logic analyzer可以有兩個mode，stream vs buffer。stream就是收幾多signal就立即傳回給libsigrok，buffer就是先儲起直至你認為儲夠再傳回至libsigrok。 我用stm32的F411和H750完成，可以看代碼，主要是main.c。因為libsigrok無可能認得你個device，所以要跟這個tutorial去改。最終效果如下

四驅車電容加速

2025-11-02 281

阿叔之無稽之談：1. 電容加唔到速：我買左四種電容，全部都有加速效果。阿叔話細電容得2.7v，加唔到速。我用4.8v charge 2.7v電容，加速度好勁。阿叔話會爆炸，我用5v charge，去埋個廁所都等唔到傳說中嘅爆炸！2. 電容唔夠力：我用5F大約有1.5秒強勁加速，用10F大約有你秒，目測個摩打快左40%以上3. 四驅車電池不足以為電容充電：我用左個5v升壓，賣2蚊人仔，充電效果唔錯。唯一就係充得唔夠快，5F要20秒，10F要50秒4. 阿叔話四驅車摩打頂唔到5V：實情係一啲事都無，摩打直頭唔熱，我估去到7v都唔會有問題
