I am hopelessly trying to connect my Arduino Uno to the MCP2004A from Copperhill. I have read several other forums threads and have come across lots of different information and have become confused.
I have my MCP2004a connected like so: TX -> TX (Arduino), RX -> RX (Arduino), CS -> Digital 6, Fault-> Digital 7 and GND -> Analog GND (Arduino). I have a 12v adapter connected to the MCP2004A breakout board, nothing connected to VBAT or VCC. The Arduino is connected via USB to my PC.
I have tried sending data (0x00) to the breakout board and I receive nothing back. The breakout board is connected to a linear actuator and sending 0x00 wakes the device and causes it to send a reference (0x25) expected.
My code pulls CS and Fault to HIGH during setup and Serial is set to 19200 baud. I have tried SERIAL_8E1, SERIAL_8N1, and nothing at all.
I have been unable to receive any data from the breakout board.
What am I doing wrong?
Thank you for your help!
