We're big-endian.
when we have this in memory:
00 01 02 03
And we need the first byte, we load the first 16-bit word:
0x0001
The first byte is then in the upper part of the word, and requires
a right shift by 8.
So any load into an 8-bit typed container needs to shift stuff.
So far, stores from/to the stack are exempted, they always load/store
full 16-bit words.
And a few othe rminor things. Like string null terminators.
And escaped characters in character literals.
Can you believe it's spelled 'literal', with a single t?
Me neither.
With:
- LED control
- UART
- PDM out
- square wave generator (DMA to PDM out (was it really necessary?))
- sample program that plays a square wave from UART values
