Re: Hacking cartridge HP 84/85

Finally i got an Teensy
I can't teach him to give a quick signal,
I used your Wonko code,
ports trick (A) (B) does not work
maybe the Teensy has no ports like the Arduino?

Re: Hacking cartridge HP 84/85

Wonko
Did you have a teensy on your way? It has these problems a lot less and runs a faster. (and is 3.3V by default)
teensy I do not have,
if you say that arduino will not repeat the desired signal then I will order teensy

Re: Hacking cartridge HP 84/85

did here what happened port (b) for some reason does not work, perhaps I burned it found ports from arduino mega Mega Port Diagram.png changed to port (a) and that's what happened 33.png and the question arose why the second output gives some kind of signal if only one first is connected viber image...

Re: Hacking cartridge HP 84/85

Can I use this method to divide the voltage for the signal outputs?

Re: Hacking cartridge HP 84/85

Hi Wonko I tried to create this signal and I only managed to create 82.47 kHz with code it is not enough 46.png int outPin = 8; // digital pin 8 void setup() { pinMode(outPin, OUTPUT); // sets the digital pin as output } void loop() { digitalWrite(outPin, HIGH); // sets the pin on delayMicroseconds(...

Re: Hacking cartridge HP 84/85

In the mean time, my printer arrived: HP something 90. It keeps switching itself off after a minute or two. I am afraid I have to return it :-(
perhaps the power supply fails but did not come across this
