biblically accurate USB-C PD communication

@mntmn Not sure that makes me look forward to requesting a higher voltage over USB-C PD.

In other news: WCH makes some very affordable micro controllers, some of which should be capable of wiggling those CC lines as good as any Space Invader

@talpa @mntmn CH32X035. Really affordable yet quite capable. Just don't expect too much of its ADC.

@sibrosan @mntmn Currently looking at the CH32L103 probably not any better in the ADC department tough

I observed in the CH32X035 that the 12 bit ADC value you get can be off by ~ 70 depending if the adjacent I/O pin is driven high or low. But I did not see that in the CH32V203. So apparently not all types of WCH microcontroller have this problem.

@mntmn Does this include USB PPS ?

@mntmn on one hand i like USB.. on the other its like 'did we put too much stuff in there over the years'

@mntmn I ain't readin' all that. You're getting 150 watts. ⚡️😎 (I don't know if that's how electricity works.)

@mntmn Wow, that looks convoluted, but butter than stuff being in flames

@mntmn is that the new rave eJay?

not biblically accurate, doesn't include an eye diagram

@mntmn first I parsed that colored chart as a Pokémon type chart where which type is effective against another.

@mntmn Why not just gimme 20 volts and up to 2.5 amps, please? Makes this meme look reasonable.

@mntmn the paleolithic version of this is IEEE 802.3af (the OG type 1):
44 V
350 mA
just there
all the time
the shocks kinda hurt though

@mntmn Oh wow, what an elegant protocol. I'm so glad this is replacing every other method for power delivery, so we all get to deal with this :P
