發個GPRS打電話和GPS收衛星的Arduino例程

ID:358930 · 發表于 2018-11-27 23:04

1.A6A7模塊需要按照供電說明供電
2.A6A7模塊需要手動開機，或者將PWR_KEY引腳和V_BAT引腳短路自啟動
3.先下載好程序，再接線，否則arduino UNO會下載不進去程序，因為下載程序和A6A7模塊復用D0和D1
注意：代碼記得安裝庫才能編譯通過

必須接的線：
A6A7模塊             ARDUINO UNO
GND------>             GND
U_TXD---->             0
U_RXD---->             1

可不接的線（用于測試調試信息）
USB-TTL模塊                      ARDUINO UNO
GND----->                      GND
RXD----->                      11
TXD----->                      10

單片機源程序如下:
