Re: Hacking cartridge HP 84/85

but I have to finish simulating the protocol,
I only managed to create 7 bit 3 megahertz
I still do not know how to write code for the second signal, so that it would work synchronously with,
and don’t know how to make a zero bit,
who can help me with this.

Re: Hacking cartridge HP 84/85

I'd love to experiment with the protocol,

Re: Hacking cartridge HP 84/85

byte pinTable[] = {7}; // Вводим вывод на тенси void setup() { for (int i=0; i<1; i++) // Ето цыкл переключения бита (0) на (1) { pinMode(pinTable[i],OUTPUT); } } void loop() { for(int i=0; i<7; i++) // Задаем количество битов { GPIOD_PDOR |= 7; // __asm__("nop\n\t""nop\n\t""nop\n\t""nop\n\t""nop\n...

Re: Hacking cartridge HP 84/85

Here is the final step
It remains to figure out how to adjust the width of the gap between the seventh bit.
and how to create another synchronous signal of another type on another pin

Re: Hacking cartridge HP 84/85

dragonator
your code doesn't send a signal to the first output
I replaced it on the seventh
and failed to get 96 megahertz
What do you advise to do?
What place should I put the delay?

Re: Hacking cartridge HP 84/85

Here at last I achieved 12 megahertz with code byte pinTable[] = {2,14,7,8,6,20,21,5}; void setup() { for (int i=0; i<8; i++) { pinMode(pinTable[i],OUTPUT); } } void loop() { for (int i=0; i<=7; i++) { byte b = 1<<i; GPIOD_PDOR = b; } } Here is a diagram and oscillogram 34623.png 2233.png Please tel...
