This target contains an application which requests compressed images from a
server (ot-eink-server) and displays them onto a Waveshare 2.9” e-Paper
module. The pin connections between the e-Paper module and the Chili are shown in the table below:
| EINK | CHILI |
|---|---|
| BUSY | PIN 31 |
| RST | PIN 15 |
| DC | PIN 34 |
| CS | GDN |
| CLK | PIN 33 |
| DIN | PIN 32 |
| GDN | PINS 3/14/16/18-25/27/30 |
| VCC | PIN 13 |
See the server documentation for a high level overview of the application as a whole, and for a description of how to generate images compatible with this application.
This demonstration requires another Chili to act as the server. Flash the
server Chili with the mac-dongle binary. You must also build the
ot-eink-server POSIX application, from within the Cascoda POSIX SDK
build directory.
Once the devices are all ready, plug the server Chili into a Linux machine
and run the ot-eink-server executable. Then, power the end device
Chili and commission it. After 10 to 20 seconds, the server will receive discover requests, as
well as image requests from the end device.
