Usage

rpi_pinToBCM(pin_number)

Arguments

pin_number

The pin as found on the Raspberry Pi board. Numbered from 1 to 40.

Value

a named vector. bcm_line = broadcom line connected to this pin pin_name = broadcom name such as RXD1 or GPIO21

Details

This checks for a valid range of pins (1:40) and for valid input/output lines. This prevents trying to read a 3.3v or ground line.

Examples

if (FALSE) { # is.rpi()
}
