Porting the EEPROM routines from IAR to GCC with the #pragma directive would probably be impossible. Porting my EEPROM routines from GCC to IAR required almost no changes (but as stated before the #pragma directive saved space, even leaving my checks in place) Porting the bootloader from GCC to IAR (since I used GCC's functions) was more aggrivation than rewriting it in assembly.
I tried to write one in IAR and opted to write it in assembly instead because I found it to be easier that way. I wrote a bootloader for GCC, incredibly stupendously simple with the functions available. If I have to stuff even more functionality into that blasted 26 then I'll look into seeing if I can remove my checks on read before write and leave it up to the compiler.īut I agree on the reliance. So I can't comment on if it reads and ensures that it needs to be written before it actually writes, but I do that myself regardless. I can't find squat about anything for IAR.
#Iar 8051 c compiler free
For the tiny26, this was significant (especially since I was working at the time with only 4 free bytes).Įither I have not learned IAR's method of documentation, or its horrid. The optimizing compilers generate very compact and efficient code. Header file stdlib.h Result Value Successful A pointer to the element of the array that matches the key. IAR Embedded Workbench for 8051: Integrated development environment and optimizing C/C++ compiler for 8051: IAR Embedded Workbench provides extensive support for a wide range of 8051 devices.

#Iar 8051 c compiler code
What I do know is that for the tiny26 i was originally writing for, when I used the #pragma directive and let the compiler handle it, my code size dropped about 20 bytes. The availability of memory depends on the default heap size, see the IAR C Compiler Reference Guide. There is no standard calling convention for > 8051. This is not an attack just a question is a libary function the best way in this case?Īs for the specifics, I don't know. What is the function like that is actualy generated by the compiler? Does it pre-read the value, first to see if it needs to be changed, does it test to make sure the value has been written, does it enable an error code to be returned if there is a fault, does it leave with the EEprom address set to 0, does it switch off the interrupts when enabling the write ( the 1.5x Version macro did not)? Here we have one of my pet hates with any 'high level language', the reliance on pre-written functions that are not actualy part of the language.
