*	Got the DMA to work! (That was surprisingly easy).	Josh Rahm	2024-11-27
\|
*	Fix CMakeLists to find objdump properly.	Josh Rahm	2024-11-27
\|
*	Some SPI is working, a bit. Still no clock, but I'm about to give up on that.	Josh Rahm	2024-11-27
\|
*	System clock is sort of working.	Josh Rahm	2024-11-17
\| \| \| \| \| \| \| \| \| \| \| \|	It appears the frequency divider does not work. I've followed the data sheet, but no matter what I set the frequency divider to it appears to not work. It's possible maybe the GPIO is using an un-divided clock, but I'm not sure. Also the 32khz clock does not work I think. It might be an issue with the board. The waveform is jagged and looks awful. But I can switch from the HSE to the PLL.
*	Cleanup and get the program to a basic Hello, World program.	Josh Rahm	2024-11-16
\| \| \| \|	Add separate source file for initializing the uart for stdout.
*	Minor changes to exception handling.	Josh Rahm	2024-11-16
\|
*	Fix exception handlers not being included during linking.	Josh Rahm	2024-11-16
\|
*	Move exc and nmi handlers to their own files.	Josh Rahm	2024-11-16
\|
*	Add panic function	Josh Rahm	2024-11-16
\|
*	Properly link against picolibc.	Josh Rahm	2024-11-16
\| \| \| \|	We now have full access to a c standard library.
*	UART is working.	Josh Rahm	2024-11-15
\|
*	Updates to how the ISR updates work.	Josh Rahm	2024-11-14
\|
*	Get a good, basic framework for ISRs and properly handle the data sections.	Josh Rahm	2024-11-14
\|
*	Added a whole bunch of fiddle files. Started improving boot process.	Josh Rahm	2024-11-13
\| \| \| \|	It still works.
*	Fix CMakeLists to be correct.	Josh Rahm	2024-11-10
\|
*	Switch to use CMake	Josh Rahm	2023-01-19
\|
*	Make submodule for ch-flash.	Josh Rahm	2023-01-18
\|
*	delete ch-flash in favor of a submodule solution	Josh Rahm	2023-01-18
\|
*	more in the readme	Josh Rahm	2023-01-18
\|
*	Start implementing ch-flash.	Josh Rahm	2023-01-18
\| \| \| \| \| \| \| \|	This is a program forked from isp55e0, but with the ability to wait for the device to be plugged in before flashing. I will perhaps add other fetaures to the program which will work better with my workflow, but this is the big change for now.
*	Added README file.	Josh Rahm	2023-01-18

*	Initial blinky commit!	Josh Rahm	2023-01-18
