Re: ESR meter upgrades

yes, blue and other similar bob-barker based designs wont show leakage.

Which ones would show you leakage that are worth a crap
Please show website links thanks

Re: ESR meter upgrades

pretty much all of the atmel based component testers - they all use the same software

Re: ESR meter upgrades

Hello
search (original) working HEX/EEP files and Fuse settings for the GM328 (AY-AT)
Transistor Tester (from Banggood) because my Atmega is broken.
The original seems to be protected against reading :-(
TX7014DH is on the Display,
thanks for a feedback

Re: ESR meter upgrades

why original?
we have newer ones on this forum if you search - i know because i built and posted them!

Re: ESR meter upgrades

which one is to be recommended that comes near to the original?
where can i download it?

Inside folder: M328KIT+TFT
You can there find Firmware in original.
But also both Madires (M-Firmware) and Karl-Heinz Kübbeler (K-Firmware)
Note that the "original" firmware is of course the K-firmware with some changes by the Chinese, but not releasing the source code

If you prefer to build the firmware from source here is the SVN repo:
The latest K-firmware: https://www.mikrocontroller.net/svnb...oftware/trunk/
The latest M-firmware: https://www.mikrocontroller.net/svnb...ftware/Markus/

EDIT: You also cross-posted here and got a reply already from Madires:

Re: ESR meter upgrades

I found the firmware does not detect PNP germanium transistors. They get reported as a diode.
Another 328 tester (2x20 LCD) I built with Karl-Heinz Kübbeler firmware does work and tests the transistors OK.

This is on AY-AT/ST7735 20MHz xtal with SVN810 STJ.

Re: ESR meter upgrades

maybe i should do a fresh build?

Re: ESR meter upgrades

That would be nice, STJ

Re: ESR meter upgrades

Hello everyone,
I'm new to the forum and I managed to do my tester, but I have a problem with the version. The font is very small. Can anyone help with the .hex and .eep files ?

Re: ESR meter upgrades

the my version is AY-AT ESR tester(SVN810) with 16Mhz quartz

Re: ESR meter upgrades

i dont have that model to test the different font options.

Re: ESR meter upgrades

I made the model M328kit + 1.8''TFT Full Color LCD Display Module 128X160 Serial SPI ST7735S. I just had one. It works great with your software, but unfortunately the font is small.

Re: ESR meter upgrades

well you could try making your own.

you need the avrgcc compiler and associated tools.
i think those are in the arduino suit.
or use a Linux machine

Re: ESR meter upgrades

Thanks for your attention stj. I don't understand anything about programming. That's why I asked for help in the forum. For now I am freezing the project or I will seek help again! Thanks again!

[stj]

Re: ESR meter upgrades

yes,
the problem with changing fonts is that you need to take into account the shorter number of characters you can fit onscreen so it doesnt wrap or make a mess.

Re: ESR meter upgrades

I won't be able to do it.
I stay like that. If anyone can help me , I will be very happy!

Re: ESR meter upgrades

This is something you etched yourself lz4pa by the looks of it? Nice work!
What MCU did you use, Atmega328p?
Maybe I will have some time in the weekend to see if something can be improved.
I did not find a firmware for ST7735S display in the massive eevblog thread but I did not look very hard...

Re: ESR meter upgrades

Hello Per Hansson! Yes ,use atmega328p in this construction. I made the scheme of M328 kit + tft display based on st7735s. I guess it's all due to the difference in the resolution of the displays. Thanks in advance!
