Jon:
  Thanks...

I'm thinking of getting rid of reset.sh since on.sh effectively does a 
reset when you rerun it.

2020-09-13 Thread jonnymo

I was able to resolve the issue I was having with your fb and pygame
examples.  I had to ensure the BUS was set to '0' and the pin GPIO values
were set properly in 'on.sh'. The same was true in reset.sh with 'busnum=0'

Also, it seemed that if I ran the examples in 'usr', I had to reboot the
board for the 'fb' examples to work.

It's all working now.
Nice job.

Re: [beagleboard] Re: pygame displaying on /dev/fb0 - Solved

2020-09-12 Thread jonnymo

Cool.

  I am unable to get your pygame or other fb examples to work but I can get
the 'usr' examples to work.

Perhaps this is for another post, but in your examples, are you using SPI0
or SPI1?  It seems some of the setup for the examples are set for SPI0 and
some are set for SPI1 yet the wiring listing in "EBC Exercise 12a 2.4 TFT
LCD display via SPI" seems to indicate SPI0.


Cheers,

Jon
