How to use serial communication on RADDS with serial Display from Sparklab ?

rgd

Hello,

i set up luc's WIFI server on ESP8266 modul and it works fine until i want to connect it to my printer board ;-) .

I only can find solutions where TX/ RX on AUX PIN row for extensions on the side of the modul are used. But there is connected my display from sparklab as you can see here:

http://the-sparklab.de/sparklcd-grafik-lcd-fuer-radds/<br/><br/>Is there any solution to use other pins on RADDS board for communiction with ESP8266? And how do i set this up?

If i use the online configuration tool for Bluetooth serial communitcation i can select 1 to 3. Is one of this selections useable for me?

thank's for any help

What does the ESP board need? Can't you just plug it into the usb serial connector?

Ask vincent from Sparklab for the adapter to put sparklab LCD on the LCD port instead. Not sure if he still has them available, but that frees the expansion port.

ok thanks that may be a solution and i will give it a try if there is no other way.

But as i understand it there must be another serial connection on LCD port if it can be used with sparklab adapter?

I wonder if it may be useable in my case to ? And can you please tell me what or where are serial 2 / 3 on radds board?

Thanks

These are also for Arduino Mega 2560 boards which have them. Not sure the due has more, but you can check pinout and check where these pins then come out.

thanks but i think that will not possible - at least for me ;) to find the right pins.

If someone tried or used it i can copy the solution but to find it by myself is little bit above my knowledge.
