Serial Bridge eISCP no connection #1

@mjiines you can hook up to a serial port on a PC and open it using an application that monitors a com port for incoming data to see if it's working. Another tricky point is there are both straight through and null modem cables. You need a null modem cable to hook up to your AVR, but you'd need the opposite (straight through) to hook up to another COM port. |
Is this still relevant? I'm sorry I haven't looked earlier into this. I must have overseen the issue. One way to test if it is working would be to modify the code so the D1 LED blinks if it receives a valid packet. Edit: Edit2: To check if it sends the correct packets, you could hook up a cheap FTDI/WCH TTL->USB stick to the D1/D2 Pins and open a terminal (like hTerm) to see if Tx is active as soon as you send a network command to the WeMos Board. |
This project likely is exactly what I am looking for.
I will have to order the MAX3232 Breakout board, though, as I don't have one right now to test this.
EDIT:
I got the MAX3232 Board today to test this out. Unfortunately, there doesn't seem to be any connection to the AVR. If I look in the Live Firewall Logs, it also does not seem to send any packets back (answer). The ESP just gets the 60128 packets and nothing comes of it.
I would go into this further if I had an oscilloscope to verify if data is actually transmitted on the rs232 port.
Maybe there is a need to "activate" the RS232 Port on the AVR itself? (I didn't find any reference to that)
Or maybe it's something else all together. At this point I fear, without actually looking at this interface with a Scope, there is nothing I can do to verify if it even works.
