Hello Robert,
Thank you for your reply. I got this link CP210x USB to UART Bridge VCP Drivers - Silicon Labs from Glyn and it had the correct driver. So is working now.
Data is coming from the EmonTx (software; emonTx V3.4 Discrete Sampling V2.80) to the serial monitor and calibrated the voltage measurement.
Trying to calibrate the current sensors, but struggling to get the current reading from the sketch. I now I have to add some lines to print the current of each 4 sensors, but what value I have to use and what the correct lines are and where to put them, is still a problem to me. Did a lot of efforts today but compiling always went wrong. Have reading a lot of sketches and topics, non of them was useful for me.
Can you put me on the right track?
Thanks, Ger
