MENG XI Posted September 7, 2020 Report Share Posted September 7, 2020 E-ink display comes in very handy in cutting power consumption when not refreshing the screen, it becomes more power conserving when combined with ARM Cortex M33 microcontroller-- RTL8722 from Realtek. This microcontroller sports dual-band WiFI and BLE 5.0 withh max clock at 200MHz, which make it possible to parse long string of a URL and generate a QR code locally. In this demo, we will show how to generate QR code and display it on a E-ink display. https://youtu.be/KYI5WBmC6ac Quote Link to comment Share on other sites More sharing options...
