Hi,
I did a modbus communication with a embedded device and a PC. Communication cable is USB. But it act as a serial port. my device has FTDI chip for communication. Now I need to communicate this device with arduino uno board. I have connected it to arduino uno via USB host shield2.
(https://www.google.lk/search?q=ardu...UICigB&biw=1366&bih=637#imgrc=n07ROJh5lK5DoM:)
I couldn't configure the modbusmaster.h file in the arduino. if i try to communicate garbage value is displayed. Can you please give me the directions to communicate with arduino uno and embedded device via USB host shield?
Thank you.
