BeagleBone Black GPIO Performance: PRU -> 1 memory mapped GPIO This test was intended to estimate the maximum performance of the GPIO, that is not direct wired to the PRU, using the PRU. The first test was done on the PRU1. Source Code #define GPIO2 0x481ac000 #define GPIO_SETDATAOUT 0x194 #define GPIO_CLEARDATAOUT 0x190 #define INS_PER_DELAY_LOOP 2 [...]
