Hello Hans and the community!
I have run into a problem with Joi-IT 16x2 display.
I connected and I think I configured everything right, checked several times.
USE_I2C_LCD is set to true and I2C_LCD_ADDR is 0x27 (checked it with i2c tools)
The buttons seem to work but the display doesn't give a sign of life besides the glowing backlight. I tried the demo file from the manufacturer to check if the screen is working in general, and it is. Shows the right bitton clicked. So i assume that the problem is with the display wiring.
Can't really find a place in samplebox to change the wiring info to check that option out.
also when I start samplebox from the console I get
(atm I disconnected the sound card and midi keyboard, they work great. Everything besides the screen works great)
is it okay that I get this?
At the moment I don't know what to do or where to find the solution.
I wrote the manufacturer to get the screen pinout but no answer at the moment, maybe you can help in any way?
Thank you in advance
