CrowPanel ESP32 E-Paper HMI 4.2-inch Display - Display QR Code

Vada · January 8

Hello,
I use CrowPanel 4.2Inch E-paper E-ink. And I can show static graphics by looking at sample codes from Github.
But I want to dynamically create a QR Code on the device and show E-paper screen. I was not successful.
Do you have a chance to share sample code?
QR Code generation library: https://github.com/ricmoo/QRCode
Best regards
