stm 8ソフトウェアアナログIIC駆動PCF 8563 T、NOKIA 5110液晶表示
23568 ワード
stm 8ハードウェアIICをデバッグして、何日かやって、人の頭が大きくなって、ずっとプログラムはwhile((I 2 C_SR 1&0 x 02))ここで、データマニュアルとネット上の各種の招待状は基本的にすべて見て、プログラムはすべて試して、ARFビットも設置して、やはりデバッグが通じなくて、最後にソフトウェアを使ってIICをシミュレートするしかありませんでした.
今回はIICドライバPCF 8563 T、このクロックチップをソフトウェアでシミュレートします.実はソフトウェアシミュレーションも難しくありません.
コードを直接見ましょう.具体的な実験現象は、画像がなく、現在ハードウェアも分解されていますが、プログラムは検証されています.NOKIA 5110のLCD画面に時間データが表示されます.
