Hi guys and girls, just wondering if anyone can help me getting this stone hmi screen running? Ive read the instructions many many times, and i sort of understand how it works, yet at the same time have zero idea how to do it!
I have the STVA070WT-01 model which can be found here https://www.stoneitech.com
I am testing with an arduino leonardo, or uno.
I also have a max3232 rs232 serial to ttl adapter to connect the display to the arduino. Also havent looked up what pins to connect this to yet if anyone knows.
I'd really like to learn 2 things
1/ how to send a variable
