[avr-gcc-list] Makefile problem and solution

Hi, in the middle of a running project I received from make the very expressive error message: .dep/blcd.o.d:1: *** multiple target patterns. Stop. I'm using WinAVR + Cygwin together. My Unix tools are from Cygwin while the avr-gcc comes from WinAVR. That works fine except for avr-gdb which I'm

RE: [avr-gcc-list] Calling C functions from assembly

Simon, the easiest way to find out how gcc would call a function, is to write a small C-programm calling the function and let it compile only to assembler by a make testprog.s, while testprog.c is the source. There you will find all details without additonal reading. You should set the

[avr-gcc-list] Inconsisten behaviour of switch statement

Hi, while the size of my programm shrunk after adding some cases I looked to the list file. I saw that a switch was converted from a structured if-then-else to a table jump (compiled with -Os). That's okay. A detailed analyses points to a gcc problem: I use a volatile variable. If a samll

[avr-gcc-list] Determine a segment length I the makefile

Hi, I know I could set the length of a segment in the linker script. Is there a chance to set it in the makefile? While the linker scripts for the avr5 are able to handle the M128-memory my M32 run out of memory without any comment - especially if I add an additional bootloader. Cheers Knut

Hi David, if you use older AVRs and do not wonder about some serious looking messages at compile time then you could use VMLAB - which seems to be out of service. It provides the ability to add some predefined peripherals like LCD, keyboard, analogue inputs and also you can simulated 2 devices at

RE: [avr-gcc-list] Shorter code?

Ruud, it looks that you use a structure to define your high and low byte. Why don't you define a union covering high and low byte structure and a 16 bit value? Gcc knows how to handle that and there is no need for shifting. I use this very often and if your CPU support 16 bit loads gcc uses them.
