Thanks to the people who helped me in this. Thank you very much.

how fast can they fire?
what speed did are you achieve

Re: Hacking cartridge HP 84/85
finally I could figure it out it was incredibly hard 14124.png byte pinTable[] = {0,1,2,3,4,5,6,7,8,9}; void setup() { for(int i=0; i<10; i++) { pinMode(pinTable[i],OUTPUT); } } char a[] = {1,0,1,0,1,0,1,0,1,0,1,0,1,0}; char b[] = {1,0,1,0,1,0,1,0,1,0,1,0,1,0}; char c[] = {1,0,1,0,1,0,1,0,1,0,1,0,1,...

Re: Hacking cartridge HP 84/85
CORE_PIN0_BIT :is which bit of a port is which pin. In this case it is said to be 3 (the 3rd bit). CORE_PIN0_BITMASK (1<<(CORE_PIN0_BIT)) :creates the actual number which is used to write the port. CORE_PIN0_PORTSET :determines to which port this is written. GPIO6_DR_SET in this case, port 6 I’ve g...

Re: Hacking cartridge HP 84/85
it seems to me (digitalWrite(pinTable[x],x);) slow to repeat simulation of a code with a frequency of 3 megahertz I tried to write code that can quickly display information from cells into which you can write the protocol model and it turned out that(digitalWrite(pinTable[x],x);) does not have time ...

Re: Hacking cartridge HP 84/85
What am I doing wrong?
code does not respond
I do not fully understand how it works
May I ask for details?
code does not respond
I do not fully understand how it works

Code: Select all
byte pinTable[] = {0};
void setup()
{
pinMode(pinTable[0],OUTPUT);
}
void loop()
{
for(int i=0; i<7; i++)
{
# define CORE_PIN0_BITMASK ( 1 << (CORE_PIN0_BIT))
}
}

Re: Hacking cartridge HP 84/85
Sadly, I do not know how to write a whole port directly yet. I did dig a little on the forum and the pages, but came up empty. Teensy 4.0 is still rolling out, and not all libraries and functions are completed. maybe you know who you can contact in order to find out how fast are we can switch pins ...
