$20 LCR ESR Transistor checker project

Slightly, but PE (especially PE0 and PE1) should be in HiZ mode by default. Or try to lift the two pins.

Lifting pin 3 & 6 did the trick,
its running now but its dead slow, the initial setup is running but it stuck on capacitor test.

its dead slow

its on default 8mhz crystal and running this firmware

[madires]

I've checked the clock settings for the 328PB and it doesn't have the full swing crystal option anymore. So you have to set the clock source to low power crystal, i.e. l-fuse should be ff.

changed the fuse settings, but no change, should i reflash the firmware ?

[madires]

No need to program the same firmware again. Usually the main cause for a slow tester is the CKDIV8 bit. When set the clock is divided by 8, but with l-fuse set to ff CKDIV8 is disabled. You could try to switch the clock source to the internal RC oscillator by setting l-fuse to e2 (just for testing if there's a problem with the crystal oscillator).

will try to install another crystal tomorow,
could it be a bad chip ?
or the firmware is not for 8mhz ?

[madires]

Since the internal RC oscillator doesn't resolve the issue the crystal should be fine. And the firmware is compiled for 8 MHz. CFD (Clock Failure Detection) switches the clock to 1MHz (internal RC plus divider) in case of a problem with the external clock or crystal, but CFD is disabled (e-fuse f4). Still, there's something wrong with the clock or clock prescaler.

It is so old tread 

Great works and projects. And I see bunch of forks 

But how I can start TT in 2019?

What fork is actual/progressive/usable now?

I`m gonna build TT with Arduino nano (https://www.ebay.com/itm/3pcs-x-Nano-V3-module-ATMega328-P-CH340G-16MHz-mini-USB-compatible-Arduino-D7-SF/323414472916?epid=11022866083&hash=item4b4d0138d4:g:neoAAOSw5sBbgfy8) and 2.9" 128*64 display since my eyes really needs LARGE pic (https://www.ebay.com/itm/128x64-LCD-Module-Display-LCM-ST7920-Controller-Paraller-Serial-white-on-Black/291836077918?hash=item43f2c9275e:g:sm0AAOSwj2Za1uv6)

[SirAlucard]

So after reading through lots of posts and trying to figure out how to go about updating the firmware on the Transistor Checker that I have, I finally gave in and figured I'd ask for a little assistance.

The specific one I have is this. https://www.ebay.com/itm/2019-Version-Transistor-Tester-LCR-Diode-Capacitance-ESR-meter-Signal-Generator/182678167951?ssPageName=STRK%3AMEBIDX%3AIT&var=485227022401&_trksid=p2057872.m2749.l2649

It looks like the AY-AT one except it says XR-116 at the top.

I can't for the life of me figure out what version this is. The buffer for the screen is a CD4050bm, Just not sure if it is a ST7735 Display, nor do I know the correct config for the firmware for this. Then to top that off if I need to set the correct fuses. So yea I keep searching, but with so many clones it's hard to make sure I have the correct one.

[Abacab]

Thats the AY-AT( same as mine) , the screen is identical as well right down to the J1 symbol next to the pins so its the standard ST7735 Display.

[001]

Sorry again
Is MK-328 firmware compartible with some other clones? 

[madires]

Possibly, if the other clone has the same display (ST7565), MCU (328 at 8MHz), pin assignment and hardware options.

What I need to drive it to 16MHz properly?

[ledtester]

I don't know if this has been mentioned already, but I just found a huge compilation of photos, firmwares and schematics of a large number of transistor tester implementations.

If you have a look at this video starting at the 5 minute mark you'll see the directory structure of this compilation being traversed:

https://youtu.be/efHyRkTYLrE?t=5m

The URL for the archive is mentioned in the video description: https://yadi.sk/d/j7lZdKsPrwTq4Q

Once you download the archive, look in the Все прошивки directory.

Edit: You don't have to download the archive - you can browse it from that web page.

[001]

The URL for the archive is mentioned in the video description: https://yadi.sk/d/j7lZdKsPrwTq4Q

It looks like some russian trojan depository, isn`t it? 

Foreign files can get to your Yandex.Disk if you log in to someone else’s mobile device. In this case, when startup is enabled, files from the device will be downloaded to Yandex.Disk.

You can stop downloading other people's files to your Yandex.Disk in the following ways:

Log out on all devices
To prevent other people's files from falling onto your Yandex.Disk, exit Yandex.Disk on all devices.

[madires]

What I need to drive it to 16MHz properly?

A 16MHz crystal and a small change in the Makefile (or alternatively the precompiled 16MHz firmware from that russian trojan depository ).

I already several times placed the reference to the archive with firmwares placed in the Russian storage https://yadi.sk/d/yW8xa5NJgUo5z
This archive is brought together personally by me and does not contain any viruses.
The person who showed the video just copied results of my work. 

[madires]

Yep, indman is the creator of that great collection of images, schematics and firmwares of the various clones.

[SirAlucard]

Thank you for verifying that, that makes it easier to go through the config files for compiling. I was just being thrown through a loop cause the LCD didn't have any marks on it at all, and the K color firmware while working didn't quite fit into the LCD properly.

There really needs to be a post explaining where all the different measurement points are for calibrating and changing the calibration settings. (if there isn't already 233 pages is a lot to read through)

EDIT: So I finally got something to show up on my tester, it loads and verifies v1.36, however whenever I test anything it just shows

Battery?
2: 3mV

I have no idea what that is suppose to mean, but it's not testing any components.

[madires]

That means the tester has tried to discharge whatever might be connected and the voltage at probe pin #2 stays at 3mV. Therefore it  assumes a battery or other power source. If the self-adjustment doesn't help you could increase the threshold CAP_DISCHARGED.

Alright, at first it started working, set the mv from 3 to 5 just in case, at first when nothing was connected I was correctly getting No Component which was expected. Then when testing a NPN Transistor it correctly identifies. It also worked correctly with a Mosfet. However when I place a 680nF Capacitor across pins 1-3 the thing just shuts down. After that when I removed everything from the tester it now shows up a 29pF Capacitor across 1-2 with nothing being connected.

Also what setting pauses the information screen after it pulls the information? Doesn't seem to sit on it long enough before it tries testing again.
