Get your AVR target board ready to go, we'll be using an attiny2313 in this example but of course you should substitute the chip you're using (in which case the code will probably not do anything). In this example, this reduces the weight by around half to 1. Eight-bit interface using software time delays. It is also produces very small and fast code. Branch instructions leave the flags they test untouched, so the code branched to or the code following the branch can use them without restriction. Both of these are available to download from the Internet. Toggle LED connected to PD4 every 100msec using Timer Zero with 1024 pre-scalar in normal mode.

Doing it in assembler is just a whole new level, especially as AVR only does 8 x 8 -> 16 multiply so you're going to have to use multiple precision multiplies, adding up the partial products. ======== mul ax, cx ; AX *= CX AX = AX * CX push ax pop ax mul ax, bx ; AX *= BX AX = AX * BX ========. To change the command, move the cursor back to the command avr-objcopy and change it to read avr-objdump, this is the program that is able to generate a file containing our original source code combined with the corresponding assembly code generated by the compiler. So AVR goes to step 4. • The HC11 is quite code efficient, but delivers only one 16th of the processing power at more than twice the current consumption • The PIC is a fast microcontroller, but the AVR delivers more than 3.
