NRF24L01+無(wú)線調(diào)試

ID:52740 · 發(fā)表于 2014-10-12 16:58

小白我前幾天做NRF24L01+模塊的無(wú)線調(diào)試，想先調(diào)通，就修改別人現(xiàn)有的程序，但是不管怎樣調(diào)都調(diào)不通，也不知道到底是收發(fā)方哪邊的問(wèn)題，以為模塊燒壞啦，就重新在某寶上買(mǎi)了兩個(gè)，依舊還是調(diào)不通。沒(méi)辦法，就到此求大神用這個(gè)程序試一下，我想到底是程序的問(wèn)題還是模塊又壞了的原因，小白不甚感激！！！
現(xiàn)程序如下：

我和你一樣的情況，請(qǐng)問(wèn)你調(diào)試好了嗎？

這樣的問(wèn)題我以前也遇到過(guò)，程序什么的都是賣(mài)家提供的都沒(méi)有問(wèn)題，但是就是不能通訊，而且模塊一點(diǎn)反應(yīng)都沒(méi)有。后來(lái)發(fā)現(xiàn)原來(lái)是電源的問(wèn)題，弄了2個(gè)3.3v得電源就好了，好像臺(tái)灣生產(chǎn)的這種芯片普遍都存在這個(gè)問(wèn)題，但是歐洲的芯片沒(méi)有問(wèn)題。
