I am wondering if this LCD display will work with Brucontrol.   https://www.sunfounder.com/iic-i2c-twi-serial-2004-20x4-lcd-module-shield-for-arduino-uno-mega2560.html

Amazon has it for only $10

here is the link to the wiki http://wiki.sunfounder.cc/index.php?title=I2C_LCD2004

It looks like it could work, but I see a different chip than the one on the Adafruit LCD backback, so I cannot day for certain. You could try it, or st least cross reference the chips to make sure they are conpatible. Sorry!

I ordered one last night, should be here tomorrow and I will test it this weekend.  Both chips have the same I2C address range.  With the sunfounder having a default 0x27 and I think the adafruit being 0x20 so I can just jump A0, A1, and A2 to ground and hope the chip can work with the same library.

I was able to change the address to 0x20 which is the same as the adafruit default.  Unfortunately, the chips are different enough where the adafruit_liquid crystal library won't work.

Sorry... the adafruit one isn't very costly... best to grab one of those.

hi is there a way that support can be added for more variants hd44780 lcds ( or just the cheaper ones on the market! ) . The adafruit one with added i2c costs 5 times as much as available elsewhere. On a big installation with many screens this adds up quickly.

Can look. We think if you have many screens it's best to put them on the BruControl workspaces, but understand the desire for local information sometimes.

hi again , have you had a try with any of the esp32 development boards that have an lcd attached  like this one <a title="ESP 32 Board" href=" removed link ;hash=item1cee3c8584:g:Fj4AAOSwbPldo~CD&enc=AQAFAAACYBaobrjLl8XobRIiIML1V4Imu%2Fn%2BzU5L90Z278x5ickkp2NA0WuhQytmt4dbStg00FlFBGFuQxX5%2BA52wm%2BGA%2Fs5HTNCPSqcEOP76xEIyuOgnXLaOC8S4rVawc%2BqQrFXIJVM6JY1zsvA%2BLh4G2WETcmyWo5RcCz3xD1PkujGy5GdQrH1emoM3OFtDIcp%2FItGvx10L1rogTUaHHVIgSefTiuXSF8cZkCxa0EvlSWUTiosa7m436N5qaXYUhGlaOA9KyT49AjOqQLfWxbpEpZd7e%2BLrfOOr8uKLbIxAbcsbzaeiIaIjsaVeO1h16rXcULRCg%2FuKk8Pc0zDIfMiIv7qWzdZCy39PpWGnTxvx%2FqAupuu7a9SXGXBiI9EnD3o1CdOxp8f5JbSpWueTvfzkRlUMSIpnE5hp%2F1W8WVBWEPSBqBEyQQRIjjftQG4suMEYcIgaIWh7tpGs851euWievH%2Fh%2Fg5r%2BqKptd1m0mGyObcS7yQoW4t%2FtU1xFeqU3jPnZR3pUGwvbxR0vzwyTZy41PQQD5o3m36qe0ORzCLDOlbzCBuRVsWjUfjbjNgtYhdNIv7RSkFDlbuQmCm0l8gOebRtuiWMUWvOMzD3%2FqR3gFm5ko%2BJgAeJmzeUinwW2KjdBKkNH%2BtJT140CPui%2BUr6fpTK3LwiR8m%2FpLcUu1ezM1%2BJO7DNvd9yrRl%2F%2Fk96MeWPxNzZLIEBmuog2StCugdhKnkIfKMdV%2FtTUmXPOWJKQxeUAICHDsFn0cj8EpyGbLnoKlfpajNOQnhhxyUoUnKyHxeOEXfhQGZ3gMKyTEdmAhD4uo3&checksum=1242560280366e38226633554a4b9a2cda2305865712" target="true">here

It would be good for local temp display etc on distributed interfaces.

@pbruno3 sorry ye i tried a few times with the insert link button but it keeps replacing with the original and snipping it. if you google or ebay ESP32 Development Board WIFI Bluetooth LoRa Dual Core 0.96" OLED Display Antenna you will see what i mean .

We don't support that OLED or LoRa. If you want something easy with the screen built in that is currently supported, check out the M5Stack Grey.

Hi @pbruno3, I was looking for a simple controller option too, so I checked out the M5Stack Grey. They aren't making that model anymore (it's marked as "End of Life"), so I picked up the M5Stack "Tough", which is similar and already in a waterproof case. I got the ESP32-M5Stack firmware installed but I havent been able to get the LCD screen working. Do you know if the M5Stack Tough should work with the current M5Stack firmware? ( https://shop.m5stack.com/collections/m5-controllers/products/m5stack-tough-esp32-iot-development-board-kit)

It should. If you compare the display hardware and its the same then it definitely will.

I have confirmed they are both ESP32 based and for the display they both use the same ILI9342C (2.0"@320*240 full color display). It also looks like they use the same GPIO's for Data and Clock, but things may have changed a little for things like CS and backlight-enable. Also, although some GPIO's are the same, it does look like they are different physical pin numbers now. Any chance you could output a firmware for this one? https://docs.m5stack.com/en/core/tough
