The first addition is a genmake +system where a Makefile may be generated with the command +`./genmake.pl > Makefile` and subsequently with `make genmake`. This will add +build rules for each `c` file. + +There are some added features as well: + +* This code loads values properly from the data and bss segments into memory so + global variables and global constants may be used. + +* This code can properly set the system clock, and does get a full 80MHz out + of it. + +* This code has a `spin()` function that flashes a "morse code" translation + of a binary error code. (1's are dashes, 0's are dots). Gives minimal feedback + until such a time where USART is implemented. |
