Materials
AmebaD [AMB21 / AMB22 / AMB23 / BW16] x 1
Waveshare 2.9inch e-Paper HAT (D) x 1
Example
In this example, we use the Ameba RTL8722 module connects to a Waveshare
2.9inch e-Paper module to display a few QR codes. The display uses the
flexible substrate as a base plate, with an interface and a reference
system design.
The 2.9” active area contains 296×128 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 2.9inch e-Paper HAT (D)
datasheet to
know more information about this module.
