QR repeating 4 rows of data
I have used your strike api code as a base to create a vending machine controller with key pad. After alot of additions to you code I have reached a point where it is working well. Even this bug doesnt stop it from working. But it does annoy me a little. If you look at my blurry photo you will see that the QR code created is repeating 4 pixels worth of rows. I haven't changed any code in the qrmaker function. Is there any obvious reason that you can think of as to why this would be happening? Thank you in advance.
I've had the wavey line thing in the QR when its not rendered properly. The addition 4 rows, seems to be repeating the QR. I wouldnt be surprised if its repeating the whole QR again (if you change line 455 to "display.drawExampleBitmap(singlehex, 20, 7, 184, 183, GxEPD_BLACK);" you could test it).
Are you by any chance repeating line 455? I say this as once the QR has been rendered to the display, the cursor will start at the end of the last QR. So once the Qr has been rendered its rendering another. Send me your code and I will have a look [email protected]
Moving the image did stop me from seeing the issue. It is no longer centred but it is also no longer weird so thats cool. Thanks for that. Also display.drawExampleBitmap doesn't work with my code. I get an error. I am using display.drawImage
