I don’t mind the IDE. For some strange reason it is like there is a separate clipboard for the IDE, so one can cut and paste within the IDE, but try and copy from another page and paste to the IDE and whatever was copied or cut from the IDE last time pastes instead.
Anyways everything was working smoothly until I tried to read the RS232 signal (2 wire only!) from my usual data logger, in order to incorporate that into the sketch data log. I have an RS232 to TTL level shifter, wired everything thing up, checked the Tx and Rx wires end to end, and nothing happens. There should be a 16 bits-long word but nothing comes out in either single bits or strings and with only two wires (Tx and ground), there is no way to poke the RS232 side into action. It is possible that the level shifter doesn’t like only one signal wire. So today’s diagnostics involves plugging in an RS232 to USB cable and seeing if the laptop can see it working...
Or get an old computer circa 1988 with an RS-232 port.
