FS#4782 - display glitches in oscillograph on h120

Thank you for enabeling the plugin for h120. I would just like to report two small glitches I am experiencing.

1) only the top half of the speed setting is displayed (see dump) - maybe it is designed for a smaller font?

2) in regular intervals (distance about screen hight) there is a distortion. It looks as if for about 3-4 pixel-lines the amplitude takes random values. This can also be observed in the non-scrolling mode. Curiously it does _not_ show in screen dumps.

At last a quick question: Is there any relation of time to (scroll-) distance? I also noticed it speeds up when the light dimms (cpu boost), so I guess it just goes as fast as it can?

Cheers 

Robert

This commit (8 Mar 08:09 Jens firmware/drivers/lcd-h100.c 1.44 Fix lcd_roll() on H1x0.) fixed the random pixels. Thank you.

However I am now encountering a new glitch. In regular intervals I get a very short peak (see screen dumps). This is "artificial" and independent of the type of music (dance-classical-folk). I tried mp3 and ogg. Cheers Robert

This commit (9 Mar 21:25 Brandon firmware/pcm_playback.c 1.104 Fix peakmeter reading off the end of the buffer, thanks to petur) has fixed it. It can be closed now.

Cheers 

Robert
