Top and bottom part of the video output croped

[cammeltech]

Edit: I will try some changes. Found several options in gbs-control-atmega.ino and a few hints in https://github.com/ramapcsx2/gbs-control projects.

The gbs-control firmware (on a Arduino nano) works fine, but I am unable to get a "full" picture from a Amiga 500. Top and Bottom Part are cut off / croped by a few pixels. Moving and scaling the picture works fine, but the result is the same (croped). Pressing Fullscreen / Widscreen let the Display go dark for about 2-3 seconds. Thereafter the picture is the same as before.

Change of: "uint8_t videoStandardInput : 4; // 0 - unknown, 1 - NTSC like, 2 - PAL like, 3 480p NTSC, 4 576p PAL" did not work.

4 and 3 compile without error but display the same output result.

2 and 1:

In function 'void applyPresets(byte)':
gbs-control-atmega.ino:1747:29: warning: large integer implicitly truncated to unsigned type [-Woverflow]
rto->videoStandardInput = 4;

0:

gbs-control-atmega:33:32: error: zero width for bit-field 'runTimeOptions::videoStandardInput'
uint8_t videoStandardInput : 0; // 0 - unknown, 1 - NTSC like, 2 - PAL like, 3 480p NTSC, 4 576p PAL
exit status 1
zero width for bit-field 'runTimeOptions::videoStandardInput'

Great piece of Software! Thank you for your work!

Your "button" on D8 should be a switch, which stays in position ;) ... unfortunately I don't have a AMIGA, so it's a bit hard to reproduce your bug with the missing lines but I'll dig into it.
