Another improvement is that we decided to create one standard for all compilations. In other
words, now always when we compile PXMC we get two libraries:
pxmc
pxmcbsp
C functions described in
point 5.3. Second library (PXMC Board Support) has our functions, which can be hardware
dependent and/or others functions which shouldn't be a part of standard PXMC library. Of
course to get right board support library, during compilation we need to set up mentioned
above CONFIG_PXMC_VARIANT variable properly.
After doing all above steps, we can very easily link both these libraries with any application just
by typing in Makefile.omk the following line:
program_name_LIBS = pxmcbsp pxmc ...
Where the program_name should be changed to the real name of the program which we
6.3. Changes in PXMC original code.
Working with Michal Sojka, we provided two small changes to original code of PXMC. First
change concerns pxms_struct. Namely we added here one field:
short pxms_hal; /* last value read from HALL sensors */
This field has two basic aims. Firstly, it is very useful during de
need first to set PXMS_PTI_b and later PXMS_PHA_b flags. Secondly, it can have some useful
meaning to keep the actual value of a hall sensor.
Second change concerns error flags. Here we added two error flags:
PXMS_E_HAL
PXMS_E_POWER_STA GE
Because these two flags were already described in subsection 5.3.2 I'll not describe them here.
