看各位大神玩NRF2401挺好玩的,所以就敗了一組回來玩玩看,我用RF24的範例做兩個NRF2401的傳輸,但是有發現一個問題,在正常傳輸下,按下主機的RESET後,從機可以很快的連上,但是按下從機的RESET後,卻要花上7~9秒才會處理主機發來的信號,我有嘗試過將IRQ的引腳拉低,也做過延遲時間,狠了狠心也試過兩個對調,但是好像沒什麼作用,請教各位大神有辦法讓這個情況改善嗎?我該從哪個地方去著手,也看過有人說要將FIFO清空,也順便請教各問論壇的大神們,怎麼做最基本的清空動作?
特別貼上影片,我的板子~~

也試過這個外國人的作法,也如法炮製的修修改改....結果~~跟沒改過的狀況一樣
http://arduino-info.wikispaces.com/Nrf24L01-2.4GHz-HowTo
ORZ 在Arduino前一個禮拜的新手......
使用器材
arduino UNR R3*2
NRF2401 *2
使用庫
RF24
RF24Network
因為改完後跟原版一樣...所以貼上原稿
(自己修修改改的程式碼,改得比阿拉伯文還要看不懂.....索性貼上原稿 )
