I've been making slow progress on getting dRonin running on the orangePI Zero; work, and other spring outside activities.
Sparkfun MPU9250 and MS5611 is connected to the zero and dRonin is loading on the board. just debugging general start up issues and now getting to testing sensors. Need to configure starting dRonin with command line options for SPI and I2C. Once this is done, add the microcontroller board for motor control, pwm input, etc. Making progress.
