An arduino component tester based on this

$ sudo apt install make git $ sudo apt install avr-libc avrdude gcc-avr subversion

$ svn checkout svn://mikrocontroller.net/transistortester

or

$ git clone https://github.com/svn2github/transistortester

• Copy the makefile from the folder of this lcd to the default (it may not necessary and can be built in it's original location)

$ cp transistortester/Software/trunk/ST7735/Makefile transistortester/Software/trunk/default/

• Go to the default directory

$ cd transistortester/Software/trunk/default

• Edit the Makefile and change the programmer setting

  PROGRAMMER=usbtiny

• Build and upload the code

$ make $ make upload
