Hi,
I'm trying to read some incoming data through the UART pins of the myRIO. The incoming data is in the form of hexdecimal, and I was following a tutorial (https://decibel.ni.com/content/docs/DOC-39303), but when I ran the attached program (SerialWriteandRead), no data was being read.
Is there a command I can use to check if the connection is working? I have tried "dmesg", but I don't know what to look for in the list. If the connection isn't there, what should I do? If it is there, how can I read the data?
Also, I'm not sure if it's relevant, but I've only connected the UART RX/TX ports and ground. Is power necessary too? If so, what pins should I connect the 3.3V pin of the myRIO to on the Raspberry Pi?
I have been struggling with this problem for a while and would be very grateful for any help.
Thanks,
Mark
