BSIDE ESR02 Pro Transistor Tester (teardown & quick test)

<< < (9/14) > >>

Hi there,
My ESR02 is the version with ALL ISP signals on J6.
I could connect the TL866 with no problems.

I then wanted to backup the old firmware but Lock Bits are programmed, so it reads only FFs.


I spent a few hours reading this Looooong thread https://www.eevblog.com/forum/testgear/$20-lcr-esr-transistor-checker-project/
but at the end, I was not able to find a link to a firmware that would fit in my BSIDE ESR02.

Can anyone help me finding the correct firmware and where to download it from?

I found this link https://www.mikrocontroller.net/svnbrowser/transistortester/Software/trunk/
but then I am lost  :-//

Regards.

Hi there,
I finally found this post where Per Hasson attached a backup of his meter firmware 1.11k.

Just one caveat to be aware of: it contains the calibration data from my meter.
So you should make a new calibration even though you will have no message telling you it's not calibrated....
And the fuses where set according to the picture included.

Atmega replaced and programmed In circuit with my TL866.
Tester recovered.  8)

Special Thanks to Per Hansson and all contributors. :-+

P.S. If someone knows how to identify an updated firmware that would fit this tester, please post a link
Thank you

That is pinout for that? Thanx

I'd be willing the buy a preprogrammed microcontroller chip if someone can mail me one. I too fried one of mine on a charged cap. I've since bought a new unit for component testing and now use an esr70 for testing caps since it will auto discharge for me... But since I'm a hoarder I didn't throw out the old unit I just tossed it on the shelf haha. I wouldn't mind spending a few minutes with hot air replacing the micro and getting the other one running again.

Hi there,
there are 2 versions of the PCB. For my version, the pinout is there https://www.eevblog.com/forum/testgear/$20-lcr-esr-transistor-checker-project/msg2698438/#msg2698438
From Top to Bottom : V+, Gnd, Reset, SCLK, MISO, MOSI

For the other version, not all signals are available from J6, as shown there https://www.eevblog.com/forum/testgear/bside-esr02-pro-transistor-tester-(teardown-quick-test)/msg1868543/#msg1868543
