Hello,
I am currently using Navio+ with Reach (connected through UART) in an octocopter and I want to add a sonar. I read in the forum that there could be some problems regarding the I2C speed (in case the sonar is connected through I2C) but I still have several doubts.
I am thinking in using this sonar http://www.maxbotix.com/Ultrasonic_Sensors/MB1242.htm but the maximum I2C speed is 400 kHz. What would be the problems associated with lowering the I2C speed?
Is it possible to connect this sonar to Reach instead of Navio+?
I saw there is also a USB sonar http://www.maxbotix.com/Ultrasonic_Sensors/MB1443.htm. Could it be possible to use this sonar connecting it to one Raspberry USB port? In this case, could the sonar values be used in ArduCopter?
Any help, suggestion or experience using sonar with Navio+ would be really appreciated.
Thank you!
