Do all revisions of nRF51 have the same 4kB RAM sections with separate RAM AHB slaves? The product specification clearly states that only for revision 3 chips.
Not really a question, but it took me way to long to find out about J-Link RTT (i.e. j-link Real Time Terminal for easy debug printing so I thought I would mention it for...
I need a fixed voltage reference on my circuit. Since nRF51822 has internal 1.2V voltage reference, I am just wondering if there is a way to use this reference for external...
Header for nRF51 (nrf51.h) mentions two peripheral blocks completely missing from chip documentation. Are they functioning? If so, the comment for PATCHADDR field of PU says...
