hello everyone i'd like to share some info and schematics for this "new" pcb/kit i bought a kit and it came without pcb, then they send me another compete kit,...

oh, forget pcb photo itself original ones:  

so because of different wiring, from reference design last display did not work at all: firmware expects display anodes on pins 17-20, while it is on pins 18-21, and 21...

I think they're trying to minimise kit parts. Or "simplify" wiring. I can try to do some testing with this hw design. If it will be hard to redesign sw...

Not tested yet, you're right. I suppose buttons will not work, because of shared pins, as @zerog2k mentioned. I think it's match easer to resolder buttons to two other pins...

@zerog2k need help i've flashed firmware with my hwconfig buttons works, indeed... looks like connection to DS1302 does not work, i checked twice, i see no error #define DS_CE P0_1...

also noticed - 3rd element displays rotated 180 deg number it's a bit strange, 1st, 2nd and 4th element displays correct image found this trying to set alarm rotation is...

issue look like the one was reported to you, but instead of displaying 1F:7F my clock displays 1b:7b first image in this thread - b:7b - 7 rotated 180 degrees...

agh... *angry* well... i've found that _missing_ P5_5, ok... but this does not work because of absence of pull-up resistors as it was mentioned in issues/30... i will try internal...

so... i've compiled @aFewBits fork... add P5_5, unflip 3d display, disconnect buttons from ligth and temp probe - and now it works just fine... temp show wrong value, but all...
