Introduction
In this example, we use the Ameba RTL8722 module to connect to a Waveshare 2.9-inch e-Paper module to display a few QR codes. The display uses the flexible substrate as base plate, with an interface and a reference system design.
The 2.9” active area contains 296 x 128 pixels and has 1-bit white/black full display capabilities. An integrated circuit contains gate buffer, source buffer, interface, timing control logic, oscillator, etc… are supplied with each panel.
You may refer to the official 2.9 inch e-Paper HAT(D) datasheet to know more information about this module. Front view of the e-Paper Module:
