Change of the firmware of the LCR T4 M328 element tester from the elektroda.pl g

Hello, the version I uploaded is 1.13 from Elektrody

can you provide the link?

here you go

Gentlemen, will you be able to buy a programmed atmel?

I think that I could only help you by programming the entire device of the atmel itself, not very someone will give you because if something goes wrong, you will solder it and it will not work. having all the equipment, you can check it and return it in working order and ready for work.

Before I change the firmware, please tell me about this calibration. You have to short-circuit all punks, have two capacitors, but how do you do it?

Prepare two sections of the thickest copper wire as short as possible (but not thicker than - say - 0.6mm, because after all, you may have too loose pins, which may not be able to catch e.g. a thin wire from now on).
Short-circuit two pairs of pins - not three, because then the measurement of R in one of the pairs is less accurate. I probably closed 1 of 2 and 1 of 3, but I will not cut my arm off.
Press the button and it will test right away. At some point you will be asked to open everything (I pulled out these wires with tweezers).
When you open it, the test will go on and eventually it will ask you to put C> 100n between 1 and 3. I used 1u.
As a result of such a carefully performed calibration, it measures the Rs of both my Rs 0.13 5% as 0.13.
I have a variant with a blue button.

Hello, the point here is that after the programmed device should be calibrated, the copper jumper will give us 0 Ohm and the capacitor, the capacity described in the instructions, it is necessary for the proper operation of the tester.

Hello, you know, I had the same thing on one of the soft, I don't remember, but uploading another started to work. I will look for it in the computer, if I find it, I will send it to you, but I do not promise anything because I do not remember if I fired it. best regards

Tomorrow I will try to give you the link I uploaded, everything is there

I too, please.

If you can, I'll ask you too.

and also please ..

Hello, not that I promised and did not share, but maybe I was not at home? not everyone is at work for 8 hours, of which 6 are on Elektroda. Today I will program one of my colleagues tester and attach the file and my colleague should write sorry.

this one measures the zener diode as i have it and this is our electrode mate.

You do not just upload, calibrate and it does not matter whether with the yellow or blue button, it is polonized and by holding down the button you enter the menu and there you have everything in Polish and clearly described

is there any other soft than atmel studio 7 (big mare)
to throw the soft last one? to the tester?
that is, to these hexes - compiled. I have avrUSB asp experience with arduino + my working atmegami tiles
but I always used the Arduino IDE - hence the lack of experience with other soft.

I found a line of code for avrdude on the net

avrdude -c USBasp -P usb -p m328p -U flash: w: TransistorTester.hex \ -U eeprom: w: TransistorTester.eep \ -U lfuse: w: 0xf7: m \ -U hfuse: w: 0xd9: m \ -U efuse: w: 0xfc: m

or a nice video of the Russians

but * .eep file required everywhere

confused; (

everything works,
I was programming the LCR-T4 (T3) NoStripGrid version
I soldered to the lower pins so as not to disassemble the LCD
I used AvrDude GUI

Thank you

@ cezare123 you asked yourself, you solved the problem yourself and left the knowledge for posterity
avrdude is a good choice if you do not need to install the entire Atmel Studio environment,
with avrUSB asp should also work with Basom AVR.

I had a problem with the drivers, the arduino IDE requires other than avrdude - and here I had a zon. the ZADIG application to replace drivers helped - otherwise windows 10 defends those installed as independence.

I installed Atmel (I had little space for ssd but cleaned a bit) - I'm struggling with compiling sources from the German site now, wanting to burn the latest version, probably 1.35 (component tester)? for logic it should be compileable - but I know atmel studio .. 10 minutes in total. and I'm struggling with some stupid "warnings" about the lack of access to files, which by the way, I added manually - but don't worry .. I'll pick it up in my free time. But AVRDude had no trouble making a copy of the software I had before - possibly going back to the previous version. Here I wanted to strengthen the transistors / I have to pair a pair with 20 ... and with zener diodes - because you can not buy 1% 5.1V 0.5W - I ordered 50 pcs. 5% and I will look for raisins. However, this Soviet soft Khazama AVR - helped a lot, confirmed the correctness of reading atmega 328p from the LCR T4 board - I knew that I had communication compliance.

after analyzing "component tester 1.35m" config / make - I'm too thin to try to configure these files for LCR-T4
it has its own hardware platform, rotarry button's although a skilled person would be able to do it.

UP this soft is 1.12k - 1.13k electrodes - and after loading it works great / there were no problems with uploading.
- sometimes / sporadically USB AVR may hang after uploading one file - this is signaled by both LEDs lit (as if the session has not ended - while AVR Dude writes that "done". Just turn it on and off, from the usb port and upload the second file.

after the photos of my LCR-T4 below - I don't know if yours often "flies" to the floor.
modifications :
box - sits deep enough that the lever from closing the pins does not fall out.
regulator 7809 in the box - gives a stable 9V from the power supply because it consumes the battery quite quickly
3x 4mm banana pins on the front panel

I'm just waiting for the hinges or considering closing with a neodymium magnet.

Hello . How to properly calibrate for the software from the first thread?

Connect pins 1-2-3 with jumpers.

This is what is known, but it is still not so easy.

Hi, you can send the batch to the LCR-T4 tester on the 16 × 2 display.

Added after 2 [minutes]:

You can send the batch with the 16x2 display, the original one is damaged.
