Hello Frank, I am interested in getting Modbus functionally from the ESP8266, can you share your code ?
thanks,
aniston.
I would love to get the code,Why is it that every scetch I find, I get it install it's libraries it won't compile, something always seems to be wrong,not in the scope, something won't named, I try with the newest verion first, then try other verions.
Here is what I would like to come up with: (or as close as I can)
I already have a program that uses a modbus master, It's part of the program.I'm wanting
to use(some what like HMI) It can Access them by serial port or TCP-ip. (I'll share that
program if somebody is interested.) What I need is the best way to implement this on a
ESP8266-12E, It wouldn't need to use all the GPIO pins (it could if need-be) I do need
to be able to pick witch: in-put - out-put - coil - read write, so on......the reason
for that, Say I have 3 or 4 maybe more of these, doing different jobs,One would not
miss up the other one, they could all act together as one interface
what I'm working with is:
D1 ESP8266 Arduino NodeMCU Compatible
32bit 80MHz ARM WiFi Wireless ESP-12E
eBay item:131715570231 & USA seller - del. quick
Any help,links, pro-cons, anything. like to hear, why, yes,no - don't do it
tell me.... I need help, can you tell?
