→ tommycc: 剛剛找到問題了，在電源兩邊跨接10uF 電容(聽說10-47uF) 08/05 00:14
→ tommycc: 就可以讀到，所以是抗雜訊能力低弱 08/05 00:14
→ wtchen: 有些nRF24L01+ module是已經幫你把電容加進去了 08/05 00:38
→ wtchen: 有時候可以把頻寬降低到250kbs應該可以改善 08/05 00:39
我按照https://maniacbug.wordpress.com/2011/11/02/getting-started-rf24/
的方式，與使用maniacbug的RF24 library
code為http://maniacbug.github.io/RF24/GettingStarted_8pde-example.html
不過不管怎樣,兩邊就無法收發
以下是Serial monitor的片段
RF24/examples/GettingStarted/

/******************************************************************/
另一邊的TX_ADDR 為0xf0f0f0f0d2
用示波器量過SPI通訊都有在送
不過就是收不到
有板友有用過這個嗎?可以提點一下我可能哪裡出問題嗎?
thanks
