The problem is the Zif connector on the development/evaluation board is not compatible with Atmega328 and so I am asking what other cheap Atmega328 compatible board I could use with the USBasp programmer and cable.
Are you just stating that the ATMega328 is a 28 pin chip and the ZIF socket on the programmer is a 40 pin socket? I'm not sure how the ZIF board is wired - so I wouldn't use it (40 pin ATMEGA16 has VCC on 10, but 28 pin ATMEGA328 has it on 7), but you can use the USB programmer piece and use jumper wires to a breadboard from the 10 pin connector on the other end.
See page 12 of the guide here: http://www.hmangas.com/Electronica/Datasheets/USBasp/AVR-USBasp%20User%20Manual.pdf for pin wiring.
I see the kit also comes with a 10-6 pin adapter so you could also use it and wire like here: http://www.chicoree.fr/w/images/b/b8/ATmega328P-ISP.png

The socket is 21 pin ... chop the end off the zif socket ... There's only 5 pins that you really need anyway.
Wow ... is it really as easy as that and nothing more is required?
Who has the TC1 firmware for me please file?
Any other method would increase the RAM usage significantly.
IIRC, the Z180SN009 is based on the ST7735S. That controller supports up to 132x162 dots but the LCDs are 128x160 usually. A 128x160 LCD module could be wired starting at different addresses. Additionally the ST7735S has three pins for setting the LCD's resolution to either 132x162 or 128x160 which implies a specific wiring offset (moved to the mid). Maybe there are 128x160 modules wired starting at 1x1 but set to 132x162. When directions are flipped we'd get offset problems. So we need an option to shift x and y by the module specific offsets to cope with all the possible variations. And there's still the issue with the additional MCU controlling some important signals. Does anyone like to sponsor a TC-1 for reverse engineering and testing?
I don't know why your tester reads larger caps a few percent low, but you could change the correction factor. Look for following lines in function LargeCap() in cap.c:Code: [Select]if (Mode & PULL_10MS) Value /= 109; /* -9% for large cap */
else Value /= 104; /* -4% for mid-sized cap */
Large cap means capacitance > 47µF, and mid-sized cap 4.7 - 47µF. Simply lower the divisor to get a higher capacitance value.
Hello everybody,
I'm a beginner in electronics and that's why I thought this tester is pretty handy for me.
I ordered one from AliExpress and since I own a 3D Printer I thought that I can print a case for it by searching for stl files on thingiverse.
Unfortunately I can't find any Stl files for my particular model. I would really appreciate if someone of you who already owns a stl file would share it with me.
This is the model I own:

I have added a protection relay to my tester. It is essentially the same as described in the KHK manual.
I'm using Markus 1.32 firmware, and I have enabled "#define HW_DISCHARGE_RELAY" in config.h
But the relay does not energize when I test a component. I know my gizmo works, because if I manually apply 5V to PC4, I can hear the relay click.
Any ideas?
