之前自己用這個(gè)模塊的時(shí)候也找了很多了歷程來(lái)測(cè)試，但是都是沒(méi)有通過(guò)，最后得出的結(jié)論是spi通信的問(wèn)題，，自己也懶得去找問(wèn)題，，所以就擱置了現(xiàn)在把調(diào)試通過(guò)的程序拿來(lái)分享給大家，可以讀卡的，其他功能需要自己開(kāi)發(fā)哦

單片機(jī)源程序如下:

//M1卡的某一塊寫(xiě)為如下格式，則該塊為錢包，可接收扣款和充值命令
//4字節(jié)金額（低字節(jié)在前）＋4字節(jié)金額取反＋4字節(jié)金額＋1字節(jié)塊地址＋1字節(jié)塊地址取反＋1字節(jié)塊地址＋1字節(jié)塊地址取反
