Feature description

C library for STM32 MCU

Is your feature request related to a problem? Please describe.
It is not possible to run the library in lib/cgo on MCU .

Describe the solution you'd like

Use emgo to transpile skycoin/skycoin library code to C , then link binaries for STM32 platform

Describe alternatives you've considered
All other alternatives for compiling with go for MCU in the end rely on Firmata, which does not fit in our use case scenario.

Additional context
Ideally this could be used to upgrade the cipher library used in skycoin/hardware-wallet. Priority consists in support for STM32F4 series.

Possible implementation

  • Transpile skycoin/skycoin library code to C using emgo .
  • Link against library for STM32
  • Parameterize the test suite (if needed) so as to test multiple implementations
  • Execute the current test suite by calling the binaries obtained in aforementioned steps

@stdevBalibrea please start working on this issue . What's the exact architecture of STM32F4 devices ? I guessed it was armhf based on STM32 @ Wikipedia article, but I might be wrong .

or maybe stm32f2 but I'm not sure:
