Hi
I'm going to use a module that uses nRF51422 and that has an adapter to be soldered as a SMD in a circuit to mimic the footprint of an AP2 module. The adapter only has 17 pins, so the vendor has mapped the I/O pins at will and I find myself with the need to write to a whole port in the 422 using nrf_gpio_port_write. The problem is that even though there are enough pins left to map a port, the mapping never uses more than 2 consecutive pins. The mapped pins are P000, 002, 003, 005, 006, 008, 009, 011, 012, 015, 024, 030 and 031.
I remember from a Nordic workshop I attended that someone stated that it was possible to rewire the digital I/O pins internally so, for example P000 was connected to pin 12. Is that true? how can that be achieved? I haven't found anything in the docs I've reviewed or in the forums (apart from a mention to "pin crossbar", that apparently is only used to change the pins used by the UART). This is the only way I see to group the 8 pins I need for a port and map them to the actual physical connections in the socket adapter.
Any help will be highly appreciated.
Thanks!
