zack如果你看到的話,向你表示致意.用AVRstdio4編譯.這是個(gè)表長(zhǎng)為100的spwm發(fā)生器的源程序,我編的,用t1的兩路比較器分別輸出正反半周期的脈沖,好處是可以直接用于互補(bǔ)型的功率輸出,表中死區(qū)已經(jīng)留出來(lái)了.如果需要不同波形,可以通過(guò)該表方便的進(jìn)行調(diào)整.如果希望交流,可以和我聯(lián)系:wql81@sohu.com
courier,not bad!
I think it would be much better if you do some remarks after every instruction.
