DIY Arduino Soldering Station
you can read also the article and comments here: http://openhardware.ro/mymatrix/ the library modified by Thomas Kovacik is made for 3 displays...there are comments in the code... I tried to made the code easy to read and easy to understand...you must to work hard :) ... if you want to have total control of this matrix... this project is just a starting point...
no... original library does not have implemented this capability... my plan is to be developed in the future ...until then... you can try this:https://github.com/tomaskovacik/arduino/tree/master/myMatrixis based on my library, but is not my project... I notice that other fonts are not completed... ready only the parts that the author needed...some digits, some letters...
No... Seems like a very interesting adapter... I do not have such an adapter... or STC12A5A60S2.
:) It is supposed to work in this way.Step1: Put electronic component in test socket. The tester is off but is connected to 9V battery.Step2: Press button (short press). The tester back to life and makes his magic... and display the result.Step3: If you do not test any other component... it stops after little time ... to protect battery.About LED... If all the others functions are correct, and LED is the only thing that works incorrectly... I guess that is soldered in reverse... or defective.Regards!

Look at step 9. I put an updated version of myMatrix there...Regards!
Try to disable optimisation for t_shiftOut in myMATRIXclass.h and myMATRIXclass.cpp: void __attribute__((optimize(“O0”))) t_shiftOut(uint8_t dataRed,uint8_t dataGreen);
I have no idea. On my Arduino IDE work fine... And I have made many updates to the IDE and core. I started myMatrix since Arduino was 1.5 or less. I think the only "starting point" is to reinstall/update library or even Arduino IDE...Now, my setup is IDE 1.6.8 with AVR boards 1.6.17 ... and Linux ... as you can see:

I know that error was in Arduino IDE... more precisely in avrdude that is bundled with Arduino IDE 1.6.xx... You can search in Arduino IDE installation folders and you will see... somewhere in .../arduino-1.6.x/hardware/tools/avr/bin... there are avrdude files...after the latest additions(of informations) you've made I only see that Arduino IDE not installed properly ... or has altered thereafter... I don't think that has to do with definitions for DIP Atmega 40, because these definitions use tools and config files that are already there... Right now I use 1.6.7 under Linux Ubuntu... and method/files from this instructable...
It seems that avrdude not "see" USBasp device. Maybe was "locked" by "Extreme AVR burner" program (You have not closed the program?)... or USBasp device have a different vid/pid form what avrdude is configured? I notice that device is working device... but message is from avrdude included in Arduino IDE... I sugest to try a separate version of avrdude... to see if working......or restart, plug USBasp in another USB socket an try first with Arduino IDE......look after usb devices in your operating system configuration to see how this device is used... what are vid/pid... and other info... Some USBasp clones (I use them too) do not have the "official" version of firmware... mine worked also in linux and windows... but maybe an updated firmware will ...see more »It seems that avrdude not "see" USBasp device.

It should work smoothly. At the time I did the project, I tried several DAW programs (demo versions) ... Meanwhile I gave up windows forever... so I tried it with LMMS with Linux and worked too.
Thank you for your words! :) I like to see some of my projects are useful. Good luck with your projects. See you around!

There are no bootloader in this setup. Just use USBASP to upload your code.
I think that softwareserial library use PCINT interrups. Atmega32/16/8 don't have PCINT at all. You can try same method as you mention above, with ATmega 1284... but Atmega1284 already have 2 serial... so no need to use software serial (unless you need 3 or more serials...)Or you can try an old version of software serial library with atmega32 and old version of arduino ide ... 1.0.xx. These are solutions that I see at the moment... maybe someone else come up with other solutions ...?
