Libraries
Background
The library for the Primer2 board from Raisonance and STMicroelectronics comprises:
- the primer2.ld link script, which defines the configuration of the microcontroller
- the debug module, which provides the ‘glue’ for the Tollos debug function
- the LED module, which provides the ‘glue’ for controlling the two on-board LEDs.
Functions that are not determined by the board but by the microcontroller that is on the board – for example, GPIO – are provided by the microcontroller library for the STM32F103VE chip used on the board.
Debug module
These functions effect I/O for the debug device (USB Virtual COM port).See pri2Debug for details.
- debugGetcIO – get character from debug device/terminal
- debugInitIO – initialize debug device (will be called before first Getc or Putc)
- debugPutcIO – put character to debug device
LED module
This function carries out the I/O for the on-board LEDs (if any).See pri2LED for details.
- ledIO – clear, set, invert, or query a system LED
