I'm trying to use an FTDI cable to connect an Elegoo Uno R3 (Chinese knockoff) to my computer. The code I'm running will upload with the USB cable but when I use the FTDI cable I receive the error:
avrdude: stk500_recv(): programmer is not responding.
My connections are 5v, gnd, tx, rx
The Uno board is selected: arduino/genuino uno
The usbserial port is selected: /dev/cu.usbserial-FTAITX1
**I make sure to press reset before uploading the sketch and I still receive this error
This setup previously worked perfectly. After a couple weeks I went back to working on the Uno and now I'm receiving this error.
**Side note: When I plug the FTDI cable into an Arduino Mega 2560 I receive the error:
avrdude: stk500v2_ReceiveMessage(): timeout
Maybe my settings are off?
