Probably many of you (including me) are using Programmers Notepad or AVR Studio to set up AVR projects. Each of them has advantages and disadvantages. For instance Programmers Notepad is great GUI, but there are lots of manual routines required to start compiling project – like setting up makefile, creating file dependencies, etc. AVR Studio is a great solution which generates makefiles automatically, and it has great simulator for immediate debugging. So why would we need another IDE? Actually Eclipse IDE is one of the best open source tools hat is widely used by programmers – so it is optimized for managing projects, code writing with auto-complete functionality. So why not to give a try for it. So lets set up Eclipse environment to work with AVR. Firs of all lets download Eclipse from https://www.eclipse.org/downloads/ site. Choose Eclipse IDE for C/C++ Developers as we want program AVR in C. Open it (no need to install) then go to HELP->Install New Software… Click Add… and in the Add Site dialogue box enter URL where AVR Eclipse plugin is located (https://avr-eclipse.sourceforge.net/updatesite/ )
UASBASP is an efficient programmer for Atmel AVR microcontrollers that works under multiple operating systems including Linux, Mac OS X, and windows. How to assemble this simple programmer read the previous article in this site or go to the original website of Thomas Fischl. As it was mentioned USBasp has two available programming frequencies – high when jumper disconnected and low when connected. These frequencies are 375kHz and 8kHz. To use 375kHz speed, target MCUâ€™s clock frequency has to be at least 1.5MHz – four times higher than SCK. If the target is clocked with low-speed oscillator like 32kHz, then jumper has to be connected as it gives 8kHz SCK which is also 4*8kHz=32kHz.
