Re: Pantum P2502W Toner Reset Chip help
This is just my theory...
The chip doesn't actually measure the amount of toner left, it just keep count.
It is programmed with a unique ID, cartridge model (there are 2 type of cartridge, 1000 / 1600 pages) and a counter.
Printer save the cartridge ID internally and start counting, perhaps save in both printer and in chip.
Some inkjets using this method can be tricked to reset and clear the ID and count from internal memory, by switching to another cartridge before switching back to refilled...Last edited by bc989; 03-25-2017, 12:02 PM.

Re: ESR meter upgrades
yes, I am now going to see if those parts upgrade can be salvage from some stuff I have around here.

Yes its bigger by a bit.

This is what it showed, pointing to function_menu.c, so I simply changed it.

Re: ESR meter upgrades
Ok for my unknown nameless Mtester clone, I got the display back by removing from your Makefile, just this one line:
[CODE]CFLAGS += -DSTRIP_GRID_BOARD[/CODE]
also to stop the compiler from choking, had to change [I]function_menu.c[/I] line 133 to:

Re: ESR meter upgrades
stj, finally got to test your 'T4 ESR tester (testing v1).zip' from page 6. Its not compatible on mine, just a blank screen.
The ones from the russian site are not working too.
Only after trying some more on [url]https://github.com/svn2github/transistortester[/url] did I find 3 that displayed something except its all flipped, mirror vertically and horizontally in all ways except the right way. The one that is still readable upside down is "mega328_st7565".
Guess I need to play with the Makefile and compile...Last edited by bc989; 06-13-2016, 07:22 AM.

Re: ESR meter upgrades
Thanks, hope a stable 3v3 will stabilize the LCD and fix the flickering while testing.
Also got the rotary encoder (green color) why it needs so much force to push down compared to original button? Surely sore fingers after many component test. Are rotary encoder this hard to press?

Re: ESR meter upgrades
Looking at the schematic and comparing to different high-res T3/T4 on google image is making me think my clone got the RESET connection wrong.
I attach 2 better pics to show difference. The 2nd pic (mine) has a via that goes to pin 30 that other T3/T4 don't use.
Thinking I should cut and reroute it to the correct pin 29....

Re: ESR meter upgrades
Before I reprogram my T3, I traced the programming pad and found the RESET pad is not connected to the atmega328 reset pin. Instead it goes to pin 30 (rxd/pcint16/pd0) see attached pic.
Shouldn't the programming pad RESET be connected to pin 29 (RESET)?...Last edited by bc989; 06-10-2016, 03:50 AM.

Re: ESR meter upgrades
Just in case, I need to revert or reflash back to recover... are there any dump of the original factory default software/firmware that came with these T3/T4?

Re: Best soldering station UNDER $50?
i'm also looking for below $50, these caught my eye for its apparent portability. anyone have tried?

Re: TC-P50VT20 10 Blink Code
Can't agree more to that. 10 blink on my PX80 led me all over the place until the culprit was found on the C3 board - a bad capacitor on 75V....

Re: ESR meter upgrades
Its pretty hard to ID them, most T3 google images show the battery cables under the LCD, but there are still a couple of differences to mess it all up.
Anyhow, great! I'll likely test with the 8MHz first. And while waiting for the rotary encoder, can I go ahead and flash the test file first? Will basic functions still work with the std button?

Re: ESR meter upgrades
I'm very keen to upgrade to your T4 code and provide answer. Can it work on my "LCR-T4 Graphical Multi-Function Tester"?
It display "MTester" only, no version number, no branding, no words, letters or numbers to ID it... like a nameless clone of a clone.
I also ordered a 40cents rotary encoder:
