Unable to print version 8 or higher on a display! #17

I'm using a NodeMCU (ESP12-E) with an I2C display 128x128px. I'm able to print QR codes with versions up to 7 without any issue, but when I choose version 8 or higher nothing happens, the display stays black and ESP8266 blinks the LED constantly (even though I haven't declared it as output or done anything with it!)

Hey even I am experiencing the same when i am trying to display QRCode on 1.8 TFT LCD display using Arduino Nano.

Did you found the solution?

I face the same issue; I debugged the code and found that it halts at the "performErrorCorrection" function during the memset operation on the result buffer. I am unsure of the reason behind this. As you mentioned, it functions correctly on versions 1 to 7, but encounters a crash on version 8 and above.
