Hi, I am building an application based on the PRU_Hardware_UART example of the "Programmable Real-time Unit (PRU) Software Support Package release 4.0" from TI. And I am using the TI C compiler v2.1.2. The UART works great.
I am able to use the GPIO pins by declaring "volatile register uint32_t __R30;" in my C source code. Then I can simply set the value of the variable "__R30" and the register value and the output pins reflect this value. This seems a bit like magic to me, how does the compiler know that __R30 is supposed to be the GPIO register? There doesn't seem to be macro expansion or similar going on. Is there a similar declaration I can use for the scratchpad registers and then access them from PRU0 as well as PRU1?
