sorry
Can I use this firmware with bside ?

[indman]

001, you constantly ask children's and silly questions at a forum! 
Do not take offense, but this is true.
Understand a simple thing - all clones which are discussed here, imeet the same basic scheme (Except for some additions) and respectively all of them can work with any firmware from Karl - Heinz or madires! It is necessary to compile it just competently.

Sory I`m really silly child sometimes. And  I can`t remember some my own yesterday posts

Hi,

I have update my firmware and calibrated. At the start-up i always read a 52pF.
My Show values are:
Ri- 20 - Ri+ 22 - CO 43pF - R0 0,020 - Vref 1113mV - Vcc 5001mV - AC0mp 0mV

Test Menu my values are:
T1 Vref 1113mV
T2 13 4 -1
T3 -10 -20 -24
T5 0 0 0
T4 I can't read, it's too fast
T6 4980 4979 4979


Thanks

[indman]

T2 13 4 -1
T3 -10 -20 -24

Did you correctly write these values?
If it is right, then you have a problem with selection of pairs of measuring resistors of 680 Ohms and 470 kOhm. Check a multimeter their nominal resistance.
In T2-T3 tests of value should be as it is possible closer to 0 and should not have difference one from another more than in 5 units.

Hi indman,

The resistors values between the IC  pins and TP are:
Pin14 - TP1 = 682
Pin15 - TP1 = 470K
Pin16 - TP2 = 675
Pin17 - TP2 = 467K
Pin18 - TP3 = 679
Pin19 - T P3 = 469K

When i measure a 1K resistors @ 0.1%   TP1-TP2 = 997.7ohms, TP1-TP3 = 995.7ohms, TP2-TP3 = 999.7 ohms

When i measure 1000uF capacitor, i read TP1-TP2 = 1719uF @ 0.00ohm, TP1-TP3 = 1745uF @ 0.00ohm, TP2-TP3 = 1750uF @ 0.00ohm

In calibration test, it never ask to put a capacitor between 1 and 3, i don't know the Markus Firmware

Thank

Hi again....

What is the folder name for the latest Karl Heinz Firmware 1.13K for these ESR ?

Left AY-AT Clone (16Mhz)
Right GM328A (8 Mhz)

Thanks

Please read the README file included in the source package!

mega328_color_kit. For 16MHz you have to edit the Makefile and recompile the firmware.

You have rather high difference in resistance of resistors 680 Ohms and 470 kOhm.
I would advise you to pick up these resistance with closer values to rated. It is desirable to install resistors with the admission of 0.1% or to select from several 1%.

I have no problems reading long threads, but this is insane...
Is there any key messages where I can learn about the best meter version to adquire?
TÍA.

[Andbro]

Before to ask a question, do you have read the README

You will find all your answer and more.

Usually you'll find the answer to that common question somewhere in the last 10 pages.

Hi.

Spanish language update with the new improvements introduced by madires.

A greeting.

[jshonw]

In Windows, I have noticed that you have to manually create the dep directory before compiling the source code for the first time.  It would be nice if this line in the MakeFile could be changed to work on multiple platforms.

-include $(shell mkdir dep 2>/dev/null) $(wildcard dep/*)

Hi, madires!
Did you check testing of DS18B20 on version 1.37m?
I have actually no DS18B20 therefore I calibrate its simulation in Proteus. Does not work - the cursor blinks though the project works at version 1.35 and temperature is displayed.
The bus OneWire is included also in DS18B20 menu
it is displayed normally:
#define SW_DS18B20
#define ONEWIRE_PROBES             /* via probes */
//#define ONEWIRE_IO_PIN             /* via dedicated I/O pin */

I also attach the updated var_russian.h file with Russian language.

General consensus is this gadget has potential if only it worked as described.  The one I got is a piece of snot.  Yes, I did run it through the calibration process several times but alas it still has inaccurate readings.

For limitations of all Transistortester clones please see Karl-Heinz' excellent documentation at https://github.com/madires/Transistortester-Warehouse/tree/master/Documentation.

... did you read the dokumentation from Karl-Heinz also?

Just checked it a few times and it works fine. The only thing I saw is a random misdetection of the pull-up resistor, i.e. the output of the pin assignment flashes very briefly. So I changed the detection a little bit to minimize the misdetection.

Have you installed cygwin?

[jshonw]

Your right, I  probably should be using cygwin or similar to avoid this problem.  I recently downloaded a new version and it didn't compile properly until I remember that I needed to create the dep dir manually.

Hi Madires,I have TC-1 with firmware 1.34, how to make measured quartz crystals? Thank
