8.2.4. How to Use Generated Sources from HALCoGen

The following steps need to be applied:

  1. Removing the HALCoGen dependency in the compiler tool:

    • remove loading the the f_hcg tool in the configure step.

    • in the class search_swi(Task.Task) the class attribute after needs to be modified. Remove the entry hcg_compiler from the list.

  2. Adding the sources:

    • The generated HAL files need to be copied into the src/hal directory

    • The wscript in src/hal needs to be modified:

def build(bld):
    """Build the HAL library"""
    source = [
        # list sources here, most likely something like 'source/abc.c',
        # 'source/abc.asm' etc.
    ]
    includes = [
        # list include directories here, most likely 'include'
    ]
    target = f"{bld.env.APPNAME.lower()}-hal"
    cflags = bld.env.CFLAGS_HAL

    bld.stlib(
        source=source,
        includes=includes,
        cflags=cflags,
        target=target,
    )

    • Add the include directory in all wscript-files where needed. This will affect most wscript-files. This looks e.g., like this for a FreeRTOS and LTC6806 configuration:
