Referring to the following Raspberry Pi 2 pinout chart:
I'm clear on all the pin functions except "GPIO_GCLK" (2nd function for pin 7), "SPI_CE0_N (2nd function for pin 24), and "SPI_CE1_N" (2nd function for pin 26).
I'm under the impression that GCLK is intended to be an output used to potentially clock another device, and that "CE" is short for chip enable or similar. I have a Microchip PIC and ATMEL background and these abbreviations are not used on those platforms.
Does anybody know of a good reference document that explains the purpose/function of GPIO_GCLK, SPI_CE0, and SPI_CE1? Any help would be much appreciated.
