GPIO utility for Raspberry Pi5 RP1

Syntax:

 gpio-rp1 [get|set] [gpio number] [options]

Runs on:

QNX OS

Options:

GPIO is a comma-separated list of pin numbers or ranges (without spaces), e.g. 4 or 18-21 or 7,9-11. Valid [options] for gpio-rp1 set are: 
 ip           set GPIO as input
 op           set GPIO as output
 a0-a8        set GPIO to alternate function alt0-alt8
 no           set GPIO to no function (NONE)
 pu           set GPIO pad to "pull up"
 pd           set GPIO pad to "pull down"
 pn           set GPIO pad to "pull none"
 dh           set GPIO to drive high (1) level (only valid if set to be an output)
 dl           set GPIO to drive low (0) level (only valid if set to be an output)

Examples: 

 gpio-rp1 get                  Prints state of all GPIOs one per line
 gpio-rp1 get 20               Prints state of GPIO20
 gpio-rp1 get 20,21            Prints state of GPIO20 and GPIO21
 gpio-rp1 get 20-25            Prints state of GPIO20 to GPIO25
 gpio-rp1 set 20 a4            Set GPIO20 to ALT4 function (I2S1_SDI0)
 gpio-rp1 set 20 pu            Enable GPIO20 in-pad pull up
 gpio-rp1 set 20 pd            Enable GPIO20 in-pad pull down
 gpio-rp1 set 20 op            Set GPIO20 to be an output
 gpio-rp1 set 20 dl            Set GPIO20 to output low/zero (must already be set as an output)
 gpio-rp1 set 20 ip pd         Set GPIO20 to input with pull down
 gpio-rp1 set 35 a0 pu         Set GPIO35 to ALT0 function (SPI8_CE1) with pull up
 gpio-rp1 set 20 op pn dh      Set GPIO20 to output with no pull and driving high
