[avr-gcc-list] array of pointers to functions - ok in RAM, fails in flash

Hi, I'm creating a table of pointers to functions, where each function is like: void func(void) { ... } When I place the table into RAM, I can access elements, and dereference those elements to execute the corresponding functions. This works fine. For example: void (*func_tab[])() = {

[avr-gcc-list] More observations: array of pointers to functions

Hi all Further to the issue of storing a table of function pointers into flash, and accessing this table accurately.. I've tried several variations, and looked at the .lst files in each case. Some variations were more elegant to the C purist, but caused severe code bloat, even at -O3. But I've

is important. All good arguments. I've dropped this whole notion, and switched to external crystals. Seems one of my suppliers offers a 13.56MHz crystal. With UBRR set to 7, this allows for 115.2kb/s serial with 4.2% error - very much good enough. Cheers David Dig Kleppe David McNab wrote

Hi, Can anyone please point me to some resources for learning about interfacing C and assembler modules in gcc-avr? I've been looking at the asmdemo code from avr-libc, but it only goes part way with overall explanation. I'm especially needing to learn how to write assembler (.S) modules

Hi, I've already embarrassed myself on this list with my early naive questions, as I battle to migrate from PIC to AVR, and I guess I'm going to embarrass myself again. What I want to ask is - what's the current thinking within the avr-gcc community with respect to documentation, and the task of
