Hipoink: Small open source e-paper display updated and wirelessly powered via NFC (schematic and source code)

Overview

HiPo is a 3.52-inch e-paper display module the size of a business card. Content is uploaded via NFC via a convenient app, no batteries required. The development board can compile different display functions by editing the code.

NFC is used to transfer text or images to an e-paper display. Furthermore, HiPo does not require batteries as it is powered by the same NFC during transmission. This is possible because e-ink technology allows for an almost permanent display on the screen without the need for an onboard battery. HiPo can be used as a badge, tag, or daily note, and any other clever application you come up with.

Quiescent current of the op amp
I was reading a data sheet and it mentioned the quiescent current of an op amp. What does the quiescent current of an op amp mean? I only know the quiescent current of a transistor amplifier.
If the front wheel is repaired, will the rear wheel still be far behind?
Once, the inner belt of the front wheel of the bike broke, so I replaced it. Later, the bike was retired. I bought a second-hand one. The outer belt of this bike was older. Yesterday evening, when I w
Technology Classroom | Cortex-M Architecture MCU Relocation Vector Table
The Cortex-M architecture uses a "vector table lookup mechanism". When an exception occurs, the kernel will automatically find the entry address of the handler from the vector table. The vector table
After compiling C and C++, and tracing with Trace32, how can I display the corresponding C and C++ code in trace32?
After compiling C and C++, I use Trace32 to trace. How can I display the corresponding C and C++ codes in trace32? Now it can only display C code. How can I debug and display C++ code? Thank you!!!!
Tell XST not to add I/O buffers?
The top module has only one input clock , but I want to use it as the input of the DCM and use it to count the delay to control the reset of the DCM. If I use it directly, an error will be reported du
