Desk of Ladyada - Some LCD and Winamp fun!
0This week we worked on some upcoming new products, including the Feather ESP32 V2 which we listed in the shop in prep for stocking next week. it's a full refresh of the Feather ESP32 and we even got low power in deep sleep - down to 70uA! we also got some LCD samples in the post and had a fun time learning how to drive these with GPIO pins on a microcontroller. finally, foamyguy threw together a little project to make a pyportal into a little audio player and we'll check that out. i've been meaning to redesign the pyportal with an esp32-s3 and this project is sort of inspiring me to get on with it.
The Great Search - LCD Segmented Display Driver with I2C Interface
https://www.digikey.com/short/3v20rr7b
This week's search is going to be for an LCD driver chip. We've never actually worked with raw LCD elements but if you do need to use one, you'll quickly note that they're a bit odd to work with and require an 'AC'-like waveform and constant refreshing. They're also very susceptible to ghosting. So let's identify a chip - ideally SPI or I2C - that will do all that drive control for us!
