Throughout twi_hw_master.c, there are lots of places where the code directly accesses PPI channel #0 and thus assumes it's available, as in:
NRF_PPI->CH[0].TEP = (uint32_t...
Hello, I have built a couple of custom boards in the past using the nRF51822 and have stuck very closely to the reference designs. They have all worked.
In my latest board...
