trezor-qrenc's Issues

Input truncted

The input is always truncated on the last character.
This is desirable when the last character is a carriage return, but not otherwise.

Just a thanks

Sorry for abusing the issue tracker for a non-issue, but I just wanted to drop a public "thank you" for releasing this code.

I compiled it onto a Verifone VX520 terminal without any modifications, I just had to change the includes for stdint.h and stdbool.h to my local versions since the oldish ARM compiler used for their SDK doesn't have them.

So generating and printing QR codes on the receipt paper is now easy as pie. :-)

RAM is using too much, who can improve?

I use STM32F103 MCU to find that RAM has high usage when using large two-dimensional code. Can we improve the use of a very small number of RAM? For example, using a bit to represent a point？

check.h file is missing...
