Burger king toy with pi zero

Ok I'll post any new developments with it here for everyone to use. Thanks

I found what the cause of screen mirroring
so no need to add anything to the config file.

options fbtft_device custom name=fb_ili9341 speed=80000000 rotate=270 fps=60 gpios=reset:25,dc:24 modprobe flexfb setaddrwin=0 width=240 height=320 init=-1,0x11,-2,120,-1,0x36,0x00,-1,0x3A,0x05,-1,0xB2,0x0C,0x0C,0x00,0x33,0x33,-1,0xB7,0x35,-1,0xBB,0x1A,-1,0xC0,0x2C,-1,0xC2,0x01,-1,0xC3,0x0B,-1,0xC4,0x20,-1,0xC6,0x0F,-1,0xD0,0xA4,0xA1,-1,0x21,-1,0xE0,0x00,0x19,0x1E,0x0A,0x09,0x15,0x3D,0x44,0x51,0x12,0x03,0x00,0x3F,0x3F,-1,0xE1,0x00,0x18,0x1E,0x0A,0x09,0x25,0x3F,0x43,0x52,0x33,0x03,0x00,0x3F,0x3F,-1,0x29,-3

Change 2 to 6 will fix this

20 Playing with this number will darken the colors " but not fix the problem "
0 to lighten the colors " but not fix the problem "


Maybe the information is not useful but I just want to share it.

Try this (it's the correct screen driver):

Code: Select all

options fbtft_device custom name=fb_st7789v speed=81000000 rotate=270 fps=60 buswidth=8  gpios=reset:25,dc:24 modprobe flexfb setaddrwin=0 width=240 height=320 init=-1,0x11,-2,120,-1,0x36,0x00,-1,0x3A,0x05,-1,0xB2,0x08,0x08,0x00,0x33,0x33,-1,0xB7,0x35,-1,0xBB,0x1A,-1,0xC2,0x01,-1,0xC3,0x3F,-1,0xC4,0x26,-1,0xC6,0x0E,-1,0xD0,0xA4,0xA1,-1,0x21,-1,0xE0,0x00,0x19,0x1E,0x0A,0x09,0x15,0x3D,0x44,0x51,0x12,0x03,0x00,0x3F,0x3F,-1,0xE1,0x00,0x18,0x1E,0x0A,0x09,0x25,0x3F,0x43,0x52,0x33,0x03,0x00,0x3F,0x3F,-1,0x29,-3

I tweaked the best I could to get a decent image, my friend and I are trying to go over all options in the datasheet to see if we can fix the contrast which seems to be the issue with the colors. The brightness seems good in my setup and I removed commands that don't seem necessary, feel free to try my settings on your setup and oh if you need to do a mirror the right way change 0x36,0x00 to either 0x36,0xE0, or 0x36,0x60.

Yay!! It works well 1000000000000%
You and your friend have done a great work
Thank you I really appreciate your help!

There is another driver I'm playing with that has much better color but needs a lot of tweaking, once I have it I'll post the setup.

picked up a couple of the BK GBC toys


a couple of things.....

the ones i got are two different sizes.....
by looking at them, which one looks similar to the one you've used....






and the most important thing....
how did you open it, the ones i have seem like their glued together....
i dont want start trying to prise it open and end up butchering it up...



thanks...

I got mine from RogerX to specifically build some pcbs for this to be an easy build so I did not open them myself, maybe ABH or someone else could respond on that.

the one I modeled the pcb for looks like the light green one on the left.

Mine it’s similar to the one on the left
There is no specific way to open it
I break it through the scalpel from the top right corner and pass it around the shell it’s hard and be careful when you open it.
