RE: [avr-gcc-list] Regression tests

Hi Mark, Can you simulate devices attached other than an AVR in this simulator? For instance, I would like to simulate being attached to a SPI RTC, some flash memory, and a number of devices attached via pins. If I could somehow write code to simulate those, I would be the happiest person!

If you take a look to the 8-bits AVR Instruction Set document, you can see that LSL Rd is implemented as ADD Rd,Rd, and ROL Rd as ADC Rd,RD. There are no specific instructions LSL or ROL. Welcome to the RISC world (REDUCED Instruction Set Computers) ! Best regards, Eric. - Original

[avr-gcc-list] Problem with debbuggin with AVRStudio, WinAvr and JtagIce mkII

Hi, I'm new here. I'm working with ATmega128, Stk500, stk501 and jTagIce mkII. i have installed on my windows XP AvrStudio 4.12 and WinAvr 20050214. WinAvr uses Avr-Gcc 3.4.3 and GDB 6.1. I have a problem with the following code: #include avr/io.h int somma(int a, int b) {

From: [EMAIL PROTECTED] [...] #include avr/io.h int somma(int a, int b) { return a+b; } int main () { int e = 10; int r = 1; r = somma(e,r); r=r+1; return r; } it's a stupid program.
