you're lucky it wasn't called marple, i was severely tempted
way, way too much Agatha Christie
is it me or are my timings about 4-5% lower ?
slightly confused by the reference to wiring, the display plugs on to the board.
board source advertised a compatible display, albeit a tad more than standard.
all the wiring is the engagement length of a pin and socket.
i've checked the schematic and the display pinnings are compatible.
if you are using real wires, what have you done with the LCD_BL connection(s?) ?
schematic says it's on PB2. the sketch doesn't seem to use or mention it.
only just spotted you've changed the 16 bit library or am i misreading it?
away to check the repo, i spotted the arduino_stm32 at 32min.
i suppose i want a check and fetch if changed script.
[e2] already had it, written the bin, still blank/black
as an aside: there's more than one version of the Black F407ZGT about, silk screen has the white angular shapes around the f407 chip, i've at least one without it.
