help me, Cheap-scope example

billylee · July 2017

Hi~

I'm trying to make cheapscope that you uploaded on the

and I also wrote down my question on linked website.

frankly said I did find valentF(x) forum today.

I was wandering in element14 communities.

here is my question.

------------------

I'm using RPI3 + LogiPi_r1.5.1 and my rasbian is 'jessie pixel'.

I did change your cheapscope example's ucf pin map from ra2 to r1.5.1. and regenerate new.bit file for logi_loader.

LED 1 and 2 is blinked properly. and my osciloscope said SYS_RX to RPI signal is transmitted when I push PB0 or PB1.

but my desk_top monitor does not display cheapscope signal as like your uploaded video (3:03). it's ok till 3:00.

what is my missing point? give me some clue.

1st clue: rpi-serial-console is not working because RPI3 doesn't support /etc/inittab

2nd clue: startx report GDBus.err but I think this is not related with it.

I have so glad to find your open s/w, h/w platform.

and I'm looking for I/F master example of SPI, I2C, 1-Wire, RFFE and etc.

pls give some tip which open example is good to me.

thanks.
