Hi there,
I'm so close to completing my SamplerBox build and it's gonna be so sweet when it's up and running, but I'm struggling to get a display working so I can see what patch I have loaded. I'm in wayyyy over my head - I've never really tried any electronics or computing stuff before in my life beyond being a mild power-user on my computers - and I've been going round in circles these last couple of weeks with this display. I'm pretty sure I've read every forum post on here containing the words display and I2C! Essentially when powering up the Pi with SamplerBox loaded, all I get is squares on the top row with no backlight.
I've got this module here which I've got working on a standard installation of Raspberry Pi OS using their demo files - see here. I've activated I2C in the boot settings and I think I've found the address to be 0x3e which I've put into configuration.txt like so:
USE_I2C_LCD = True (have tried 16x2 as well as per a couple other threads I read but to no avail)
I2C_LCD_ADDR=0x3e (I've also tried 0x60 as that came up in i2cdetect, as well as a bunch of other addresses I found for similar displays like 0x27, 0x3f, 0x70 etc. which didn't work either of course!)
I've tried digging through forum posts both here and elsewhere but my guess is there's something I've not done that would be apparent to someone who actually knows how to program a computer! Any suggestions or help would be amazing. I'm using a Raspberry Pi 4.
If you're interested, this will replace my old Akai MPX16, a horrendously slow and cumbersome device that I've been struggling along with for too long. It finally died after a tour last year leading me to find SamplerBox which I can't wait to take on the road. I really appreciate all the work that's gone into creating SamplerBox over the years, what a fantastic project!
Cheers gang,
