坛里的高手们有谁用过UB-93这款GPS模块?本人在使用过程中,老是收不到正确的定位信息。收到的信息如下:
$GPGGA,011006.060,8960.0000,N,00000.0000,E,0,0,,137.0,M,13.0,M,,*43
$GPRMC,011006.060,V,8960.0000,N,00000.0000,E,0.00,0.00,060180,,,N*7E
$GPVTG,0.00,T,,M,0.00,N,0.00,K,N*32
$GPGGA,011007.060,8960.0000,N,00000.0000,E,0,0,,137.0,M,13.0,M,,*42
$GPRMC,011007.060,V,8960.0000,N,00000.0000,E,0.00,0.00,060180,,,N*7F
$GPVTG,0.00,T,,M,0.00,N,0.00,K,N*32
只有关于时间的字段以一秒在累加,其它的信息字段都不变,请问有没有遇到类似情况的朋友?
还有DATASHEET里面有提到说GP_RF_IN这个引脚有2.85V的直流输出,我用表量了一下没测到这个电压。这是不正常吗?
GPS_RF_IN(pin名称) I(输入) GPS signal input(DC:2.85V output)(功能说明)
