Re: [Software] Joyport SPI Master

I forgot the CS line is used to synchronize packets/byte between master and slave.
A direct implementation is impossible as there are only 2 output PINs on the joyport.

Crap...

[Software] Joyport SPI Master

I'm putting this here as I don't if I'll ever find time to implement it. SPI is a rather simple bus. It only uses 4 pins, SCK, MISO, MOSI, CS. Long story short, joyport SEL and CLR can be used for SCK and MISO, any of the D0-D3 lines can be used for MOSI, and CS can be directly wired to GND. The cod...

[Hardware] Pachinko controller

Here are some images of the pachinko controller guts. Although it was sold by Coconuts Japan, the PCB seems to have been designed by Hori. http://blockos.org/releases/pcengine/hardware/Pachinko/thumb/pachinko_back_00.jpg http://blockos.org/releases/pcengine/hardware/Pachinko/thumb/pachinko_back_01.j...

Re: [Hardware] Analog joypad

It seems that the code after l_f6cd is about moving hgfedcba into 0000bagh . Bits a and b being Select and Start. Anyway the 19 lines of codes that computes this can be reduced to : lda $2a30 asl A ; A=gfedcba0 carry=h rol A ; A=fedcba0h carry=g bcc l0 ; if(carry != 0) A |= 0x$02 ora #$02 l0: ; A=fe...
