I want to control the HPS GPIO from the HPS and send a reset signal from the HPS to the FIFO. (Run the C file from the on-board Linux and using memory mapping send a signal from the GPIO to the reset pin of the FIFO whenever I run the C file so that I get fresh samples ...

在FIFO溢出之后函数是直接返回错误信息的,我们可以在reset_fifo之后重新读取一次fifo,也就是重新执行一次该函数,我是用了goto回到函数起点。这样就正常读取了欧拉角数据。 至于dmp-init出错,我也碰到过。我的是在dmp-init中的self_test未通过,把模块放正就通过了。 回复 使用道具 举报 ...

while(mpu_dmp_get_data(&pitch,&roll,&yaw)!=0){} 就是上面这么一句话,如果读取失败,马上进行第二次读取,这时候FIFO一般没有溢出,搞定!(因为检测到FIFO溢出后会马上reset一下FIFO)。 最后上一发图: int dmp_read_fifo(short *gyro, short *accel, long *quat, ...
