了解Pulseview Logic Analyze背後運作 2026-01-10 215 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
