Is it possible to program the cortex controller completely in assembly?
if so, how would I go about doing this?
Edit: Grammar
Assuming you knew the microprocessor it has (the VEX site says it has an STMicroelectronics ARM Cortex, with some specs on RAM/FLASH, so that should narrow it down), and how the master communicates (I know it uses SPI), you should be able to do that. You could also use GCC/G++ for ARM, and cross-compile to that if you don’t like EasyC.
Warning! OCCRA officials and staff will not support any software other than the supplied EasyC V4 ( for Cortex and EasyC v2 for vex).
If you choose another software it may not be compatible with our field control software and we will not take responsibility if you cannot communicate and therefore run in a match.
Unless you have an absolutely great reason to use assembly code while competing with an OCCRA robot, please do not attempt to use assembly language coding. Please contact me if you are seriously attempting to go down this path - I will discourage you and encourage you to use EasyC V4 Cortex for the OCCRA competition. We don’t have the software tools in house to debug and support this effort by students.
