Thanks madires,.......................I've attached a the picture of the one I bought fromEZM and it works great,........................
I have the yellow tester that Tom666 mentionned in an earlier post (T3_T4 ST 7565 tester). When I go into the function menu and select Frequency, it shows me Frequency f = 0HZ, and a second later a blank screen. It seems to be locked on the blank screen because whatever I do (press the button short press, long press, etc.) nothing happens. I have to disconnect the battery to be able to restart the tester.
I am running version 1.12k release 508.
Is there something wrong with the function Frequency or is it just my tester?

For the pot read my last message a few posts above.

This is the one I have....no programming port....Sigh! I missed that. Mine does not have the pot. Just putting mine in a case now. Guess I'll have to parallel program update it using my TL866 but I think I need an external crystal and are a little unsure. Think my firmware is 1.11 or 1.12...sorry don't know as I've removed the LCD to lower it and the ZIF socket atm. I'll post back when done in the case.
hi
does atmega2560 version support all feature like atmega328 version?
Mine is also missing the programming pins, but my local electronics place had UNO on sale for $5, so I grabbed one, I'll remove the chip and add a ZIF socket and just use the UNO board to program it for now. I think it will work, I've never messed with uno avr before, but sound logical.
If not, I will still get to tinker and learn :-)
No, my display is working fine for everything on the transistor tester...only the function menu Frequency blanks after a second or 2 into the menu and then the tt is frozen...only way to get it back to work is to unplug battery.
When I unplug battery and start the tt, it works just fine. Can't get the function Frequency to work however.

It will not work!
The only option is to use the Arduino as an AVR ISP programmer. But you'll need some an AVR ISP adapter, which will be used to interconnect the Arduino and the AVR MCU.
The necessary information you will find here:
https://www.arduino.cc/en/Tutorial/ArduinoISP
Instead a breadboard you can use this development kit:

OK, but It would be better and cheaper solution by buying the USBasp and this AVR ISP adapter - total price is US$1.87 + US$1.87. The USBasp programmer can also program the ATmega2560 (see. the list of the supported MCUs).

If you have a Pi (any one), you can program your Atmega. There are a lot of tutorials to do that, one of them is https://projects.drogon.net/raspberry-pi/gertboard/ It uses the Gertboard but you can use a breadbord with the minimum required components. It also uses a modified version of avrdude which allows to use gpio pins. Works very well here.
... But the reason I'm looking at using the Pi is because I believe I would be able to flash the boot loader also on blank chips. That may be the only difference with the writer you recommended not being able to write the bootloader? ...
... I deal a lot with 3D printers and you would be amazed on how many people flash it with the wrong hex and overwrite the bootloader.
So I think the Pi and modded avrdude 6.1 or higher will give me this option to help people fix their boards that run the 1280 or 2560. ...
... But if I had to guess this is about using IDE to restore a bootloader if you over wrote with AVRDude.
From what I understand, this could take hours to do?
I'm not sure if Makerbot writes the proper locks on the MCU, I do know someone else that does it with a smart programer so I believe it might be possible. ...
... For some reason I got the impression that using the Pi would be more like using a smart programer without having to spend the $60 ...
... I guess that was my thought in direction and didn't want to spend another $60-$80 on a smart programer ...
... But if a parallel programer is needed then I'm out of luck ...
... Or will that still need a smart programer? ...
... How much faster is the smart programmers, are they worth the money, or the $20 to build one from adafruit? ...
I also noticed that IDE on the Mac is using AVRDude in the background for the programming, so IDE is just a sketch editor, compiler and AVRDude does the flashing?
So what is the advantage (if any) of running the full raw AVRDude over using IDE besides being able to use some switches like -F for ignoring the signature of a chip? And even that could be fixed in the conf file.
No, my display is working fine for everything on the transistor tester...only the function menu Frequency blanks after a second or 2 into the menu and then the tt is frozen...only way to get it back to work is to unplug battery.
When I unplug battery and start the tt, it works just fine. Can't get the function Frequency to work however.
As I wrote above, everything works normally.
