RT-Thread QR Code App

QRCode

This project is forked from RT-Thread Package QRCode, which in turn is forked from Arduino Library QRCode.

Dependence

• RT-Thread Library

Supported Architectures

• SAM (ARM Cortex-M3, Tested with Arduino Due)
• SAMD (ARM Cortex-M0+, Tested with Arduino MKRZero)

Build As MSH Command

• Uncomment the line with // RT_T.begin(); in "QRCode.ino"

void setup() {
  // RT_T.begin();
}

• Add the following line to "shell_cmd.h" (in RT-Thread Library)

ADD_MSH_CMD(qr, qrcode generator, qrcode, int, uint8_t argc, char **argv)

Build As RTT Arduino App

• Compile

  • You may copy the compiling command from Arduino IDE's output window (select "File-> Preferences-> Show verbose output during: compilation" if you can't see the command)
  • Insert options -mlong-calls -fPIC

• Link

  • You may copy the link command from Arduino IDE's output window
  • Keep only "QRCode.ino.cpp.o" and "qrcode.c.o`
  • Remove option `-Wl,--unresolved-symbols=report-all"
  • Remove option -L...
  • Remove option -T...
  • Remove option -Wl,--start-group ... -Wl,--end-group
  • Insert options "-shared -fPIC -nostdlib -Wl,-marmelf -Wl,-z,max-page-size=0x4"
  • Insert entry point option (e.g. "-Wl,-eqrcode")

• Strip

  • Use arm-none-eabi-strip to strip unused sections, e.g. .hash, .comment and .ARM.attributes
