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

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

Re: Hacking cartridge HP 84/85

Wonko Can i repeat this signal with arduino? test.png Well 5 volts I can pick up a resistor and lower it by 3.3 volts. With this problem, no, I think so. the most important thing is to repeat this signal in the picture I already had time to study 50% с++ and programming in Arduino has also been mas...

Re: Hacking cartridge HP 84/85

the printer shows a printhead problem in which I closed the contact I checked all the contacts with an oscilloscope and did not find an analog signal With a needle for supplying ink, everything is okay, as a last resort, i can make a hole in the carriage in white. There is ink there because I take o...

Re: Hacking cartridge HP 84/85

I tried to block the contact with tape and the printer gave an error tried any contact I think it is connected with the fact that the rest of the contacts do not stick out of the thickness of the scotch Scotch was very thin, used Kapton or the printer simply recognized that the contact is not connec...

Re: Hacking cartridge HP 84/85

and what protocol does hp 45 have for data transmission
I can not find the protocol with a seven-bit clock
there is at whom that oscillogram hp 45
I have not yet started to connect to arduino, waiting for materials with aliexpress
