Firmware example for Vusion/SES-Imagotag GL120/GU140, CC2510 based electronic shelf labels. Feel free to make your own based on this. Still under development and never to be completed. This thing is used as a playground.
Original repo andrei-tatar/imagotag-hack
- CC2510 - MCU + radio - 8051
- NT3H2111 - NFC
- GDEW026Z39 - 2.6" EPD display
- or GDEW0213Z16 - 2.13" EPD display
- or SE2266FS092 - 2.66" EPD display - no datasheet yet
- or EL026TR3 - 2.66" EPD display - no datasheet yet - similar to SE2266FS092, used in GL440, compatible with all above
- all the displays use IL0373 or compatible driver
- TPS61071 - boost converter - used (only?) for white LED
- W25X10CL - Winbond 1Mbits NOR SPI flash
- P0:0 - EPD power enable (active low via a P channel fet)
- P0:1 - EPD CS (SPI interface chip select)
- P0:2 - debug port
- P0:3 - EPD SDI (SPI interface serial data in)
- P0:4 - SDA to NFC chip
- P0:5 - EPD CLK (SPI interface clock)
- P0:6 - SCL to NFC chip
- P0:7 - not connected
- P1:0 - NFC VCC (seems to power NFC chip and SPI flash)
- P1:1 - NFC FD (field detection)
- P1:2 - EPD DC (data/command select for display)
- P1:3 - EPD BUSY (detect if display busy)
- P1:4 - SPI flash CS
- P1:5 - SPI flash CLK
- P1:6 - SPI flahs MOSI
- P1:7 - SPI flahs MISO
- P2:0 - EPD Reset (display reset)
- P2:1 - debug data and white LED
- P2:2 - debug clock and LED boost chip enable (TPS61071)
