I hope it's ok that I post my question here as it is highly related. I would like to interface the MCU of my Plugged (r)evolution BT with this USB FTDI cable, as I wish to use the 3D printed housing and have little space for additional boards:https://www.flikto.de/products/ftdi-cab ... c-3-3v-i-o
I read around the forum about UART connections and found that
- I shouldn't need to connect the STAT pin, as it has an internal pull-up -- and I noticed that this new board does not even have a STAT connector anymore (but an additional GND in that place), so I shouldn't need to worry here
- I also might not need to connect the RST -- which is no longer part of this line of 6 soldering holes
- I should not connect the DVCC, as I might damage the power supply of my board -- particularly as this USB cable yields 5 V VCC
- I probably won't connect CTS, as it is pin 6 on the board, which is not connected in the demo video on Youtube
So should I just connect GND (1st pin), RX, and TX? Would that work?
I always wondered, whether STAT on the BITalino is actually CTS (clear to send), and RST might be RTS (request to send). But I guess, the story isn't that simple, right?
Btw, this setup will be operated from a mobile PC, so neither line noise nor the danger of a surge will be an issue
EDIT: Do I need to solder anything on the MCU board in this case?
