Timon 🛠Whats with embedded devs and coming up with weird new ways to calculate a checksum.
Today I found through trial and error the checksum for a UART message protocol:
checksum = (0x08 - byte[5]) & 0xFF
Did they just roll a dice on this or smth
Graham Sutherland / Polynomial@timonsku that screams buggy implementation lol
@gsuberland tbf it seems like only byte 5 out of 8 ever changes lol
