Re: AXA Remote 2.0 and ESP Easy
Yup, rock stable with 2 stop bits, been running a load test sending a version command each 1/4'th second, each one gives the correct reply :) Only if I don't send anything for ~10 seconds, the first command isn't recognized.. :( I'm hoping that's something to do with the usb<>serial converter I'm us...

Re: AXA Remote 2.0 and ESP Easy
And something new again Just spotted that at the bottom of the hyperterminal window in the 'AXA pdf', it shows two stop bits!
Using that I no longer need the delay

Re: AXA Remote 2.0 and ESP Easy
Wel, learned more still. Seems that getting each character back is normal, RXD follows the LIN bus, which includes what you send yourself :) And things seem pretty stable when you send characters slowly, at full speed it almost doesn't work, with a delay (right now how fast I type, using putty :) ) ...

Re: AXA Remote 2.0 and ESP Easy
Well, I know some things by now :) - The serial output of the MCP2003 is open drain, which means it only connects to ground, and you set the voltage with a pull up resistor, which can go to 3.3V, yay for that :) - The MCP2003 thus would be powered from the 7.5v used by the AXA. - I don't know if the...

Re: AXA Remote 2.0 and ESP Easy
Otje, have you got any diagrams for how you wired this? I'm mainly interested in how the MCP2003 (I assume you used one?) connects to the ESP, and how the MCP2003 is powered. My big concern is voltage levels. ESP power should be 3.3v, and logic levels of the ESP should be 3.3v. MCP2003 data sheets s...
