arduino wire library not receiving all the bytes

Thank you very much for your prompt response! Indeed, this would be a great idea, if we were using dronekit from the beginning and the total system was build around it.

In this case must I modify the above C++ code for slave or not? I use python scripting through Mission Planner to control the hexa.

Is it possible to write a Python code through MP in order to communicate through I2C from Pixhawk to ARDUINO?.

to use MAVLINK lib in ARDUINO NANO and to communicate through Telem2 for example to Pixhawk, or.

I must replace the master ARDUINO MEGA with the PIXHAWK flight controller of a hexa and read the above message '41.139234,24.912345,67.25 ” through one of its serial ports (UART or I2C).Ĭould you please suggest me which is the easier solution: Void requestEvent() // this function is registered as an even function that executes whenever data is requested by master Wire.onRequest(requestEvent) // register event Wire.begin(10) // join i2c bus with address #10 Wire.requestFrom(10, 27) // request n=27 bytes from slave device #10Ĭhar c = Wire.read() // receive a byte as character Serial.begin(9600) // start serial for output

Wire.begin() // join i2c bus (address optional for master) Using the following code they communicate correctly:

I need your help in the following simple(?) issue: I have connected through I2C two ARDUINOs (a master MEGA and a slave NANO).
