MWC GPS问题

tony1157 · 发表于 2014-6-16 23:39

鼓捣了几天，终于搜索到信号了
GPS模块直连电脑定位正常，连接I2C转接板后，转接板上的指示灯以每秒3次的频率闪烁，证明搜星正常
然后在GUI里面就是这个样子了
GPS_fix那里变绿了，但是各项数值显示都是-1，I2C　Error和cycle time 那里的数值也是一会大一会小
不知道哪里还有啥问题，麻烦各位给看看

导航板的红灯正常频闪只代表了GPS和导航板的串口通讯正常，不代表导航板和主控通讯正常。请检查一下导航板固件和主控固件的I2C GPS通讯协议是否匹配。

请问这是个什么界面啊，求指点。

导航板的config代码
直接发代码报攻击，只有发图了

两边的I2C gps都打开了波特率115200

MWC的高人來個回覆啊

luyonghui · 发表于 2014-6-18 09:01

还让解答什么？导航版指示灯每秒闪三下就说明搜到卫星了，该定点就可以设置调试定点了，你管他那个数据忽大忽小呢

请问楼主，买来的导航版（转接板）是不是要单独刷代码才能用，如果是，代码在哪里可以找到啊

搜索 I2C GPS NAV,谷歌代码上有
