/**
|
|
* There is a good chance the PY32F002A you got is a relabeled PY32F003X6
|
|
* or PY32F030X6, this code will test the hidden resources of PY32F002A
|
|
*
|
|
* 1. Fill flash to 32KB
|
|
* 2. Fill RAM to 4KB
|
|
* 3. Enable PLL to make system clock run at 48MHz
|
|
*
|
|
* Notes:
|
|
*
|
|
* 1. Before compiling, edit Makefile, change all options to PY32F030X6
|
|
* instead of PY32F002A
|
|
* 2. In case the code size exceed 32KB, edit dummy_data.h and dummy_data.c
|
|
* to shrink the array size.
