Why this bootloader is different? This is based on standard Motorola s-record compatible file which can be easily generated from Intel HEX. Firmware can be transferred via standard UART of any AVR microcontroller. File can be transferred using any Hyper terminal program or your own program. Just note, that it is necessary to have a delay of 250ms after each line transmitted. This can be set with almost all Hyper terminal program.
Download process can be automatized by using command line tool, which can be called from Makefile or another application.
GNU Compiler Collection or GCC is free and have been around for a very long time. GCC is supported bu volunteers. This means there is a big community where you can find help for free and from different sources – but response can take longer or you want get at all.
But there is several significant advantages of GCC compiler collection:
GCC is available for many different processors like x86, AVR, ARM;
Code is very mature and works well. It is also well documented.
Program Flow and control is a control method of your program. For example Loop constructions control repeated execution of repeated program segments where control is taken by control parameter. In this article we will go through if/else switch/case statements and loop sentences like while, do while, for.
While statement
As I mentioned three looping sentences available in C language one of them is While sentence. Lets take an example:
This is good news for those who more than one working places. It is not convenient to install separate WinAVR development toolsets in separate computers and care about them. There is a solution. Now you can run your WinAVR suite directly from USB memory stick or other portable media without prior installation. You can download it from here Portable WinAVR its Free.
