The optimizations found on MPLAB ® XC C Compilers provide code size reductions and speed enhancements that benefit your design projects.
Thank you very much for your tutorial!! You are a genius! Now i have two problems/doubts (first of all, im using MPLAB X IDE v2.26 and XC8 v1.33 with a pickit3). C but I often had to dive into the asm of the generated binary to optimize it. With this movement, Microchip provide to their clients a cheap and decent C compiler as their old and deprecated C1. What is wrong with the ASM generated by the XC8 compiler?įinally we had “reasonable efficient” tools to program Microchip microcontrollers in C! Two years ago Microchip bought the Hi- Tech company and renamed their Picc compiler as XC8. Half size and less than a quarter of the time needed to execute it. Few memory, scarce resources, small instructions set, few addressing modes. Those cores were so simple that it was not easy no make a C compiler for them. Those days Microchip had only what we know nowadays as the. But the fault was not in the compilers manufacturers, but in the PIC core architecture. As far as I remember, only Hi- Tech, IAR and CCS had compilers – not even Microchip has his own one – and they were quite horrible compiling. When I started to program PICs microcontrollers in 1. In fact, I even used to hate it due to the poor quality of the C compilers. I don’t like to program PICs in C language.
