Need to think a bit more as it requires the test library, which isn't
immediately available...

Likely need to make this a proper package and put the library there..

One missing thing is the ability to generate public keys from
private keys for running the code standalone..

This also makes sure that the command works, and verifies that
a previous fix did fix things...

this also sets up for testing the public key version as well..

Slightly buggy in that it assumes all arrays are numbers though..

This was for a project that is now partly abandoned due to cell
phone camera limitations...

I'm temporarily abandoning this because the issue is that the camera
isn't a great sensor.  Issues w/ long shutter speed (blurs sampling
period), and sampling frequency makes this difficult.   I cannot
find api information about how to adjust the shutter speed in app,
though there does appear to be able to do this via other apps...

This is sample code, but works well.. it ensures that every bit
time there is a level change, so any duplicates can be dropped..

this works so far, but I'm sure is not the most effecient way to
do this...

minor improvement to make sysinit_run a constructor, so don't need
to manually call it anymore...

This required updating the linker script for the l1 part to include
the linkerset section..

This is to help make sure everything you think is starting is..

This will need to be fixed up a bit to handle when a bit gets
doubled due to when two frames have the same bit as the frame
length will be around 33.3ms and the bit length around 34ms, which
means around every 52s, the same bit will be split over two frames.

This refactors out a bunch of code to make better use of the
SYSINIT mechanism...

Completes the PKI side of things for doing mutual authentication...

Uses a python script to generate the USB descriptors, and basic
interface code for the STM USB HAL Layer..  This gets ride of a lot
of the glue code that was previously written, allowing the glue code
to be easily changed/update...

break out the memory debug function into it's own file...

Minor fixes to the rs485 framing code...  Finally found the bug where
aborting a receive would corrupt the RX state for some reason...

Add back RNG seeding, and make it generic...

it's promoted to int (signed) which when shifting into the sign bit is
UB per §6.5.7 ¶ 4 of the C99 spec.

ST if free to contact me about licensing the code (or improving their
own code to be USB standard compliant)..

This follows the same protocol as the lora code, so the same
server should just work.

This gets USB CDC printing working..

add some more missing files now that it includes the symbols..
