Small monochrome displays

Recommended Posts

@Larry Bank I happened across these again:

They might be used, or they might be quality rejects for actual product, I'm not sure.  There are other options from the seller, I haven't gotten any yet so can't speak to the state they're in.

I have three of those (5110 screens), don't know if it was the product / the soldering / .... but only one of those is working with spec (PCD 8544) SPI speed. For the other two I had to lower the bus speed and play with LCD bias / contrast to make them work and they finally worked.

 

I don't know your use case but those 5110 display use less power comparing to small OLED.

 

Certainly due to my laziness I prefer the small i2c OLED (only 4 cables). I still use the 5110 for an arduino running on LIPO.

Thanks for letting me know. I really dislike that particular display. The frame/contacts are always flaky. For those applications, my preferred screen is the HX1230 (96x68) or the 128x64 LCD under various names.

@TonyMac32, which library did you use?  Btw, in Larry's Arduino-Folder you have to delete the hx1230_turbo.ino  this is a 'double' and in the .h file are 2x double entries. If I was better at ... if I knew how to do pull requestes I had sent some.

I haven't tested the LCD1202 yet - looks nice too.

 

Libraries:

U8g2 https://github.com/olikraus/u8g2 

hx1230 https://github.com/bitbank2/hx1230
