* Change rcc.h to define regset() macros.Josh Rahm2020-11-18
|
* Add regset masks to gpio.hJosh Rahm2020-11-18
|
* Change dma.h over to a regset() strategy.Josh Rahm2020-11-18
| | | | | | Apparently people really don't like bitfields in practice, so I have devised a compromise to retain some readability while using bitmasks instead by writing a regset() macro.
* Reorganize some file. Put thte core register libraries in a core/Josh Rahm2020-11-18
| | | | subdirectory.
* A basic blink program that works off of interrupts.Josh Rahm2020-11-18
| | | | | | | | | | | - The init() function renamed to on_reset() - on_reset() now responsible for tight-looping at the end - on_reset() now set the VTable offset to the base of the FLASH - included exhaustive list of irqs in isrs.i - interrupt routines by default flash a code indicating their isr number. - interrupt routines are weak-linked allowing the programmer to override them at-will.
* add lib.h/lib.cJosh Rahm2020-11-18

* Add the System Control Block (SCB) in system.h.Josh Rahm2020-11-17
|
* Changes to genmake.plJosh Rahm2020-11-17
| | | | | | | | - genmake.pl now handles generating the idempotency hash rather than relying on a less-portable bash command. - genmake.pl now recursively looks for *.c files in src/ and tests/ so the directory structure no longer needs to be flat.
* Got the DMA to send a simple message through UART2.Josh Rahm2020-11-16

* Update the genmake script for tests.Josh Rahm2020-11-16
| | | | | | | | Update the genmake script to do the following: - Fix bug to link the object files from the source. - Test build output goes into a build/ directory. - Test makefile rules now run the test after building.
