GPIO
Description: Configures digital I/Opins level to high (1) 5V or low (0)
0V for output pins. Nothing happens if the pin is an
input.
Syntax: GPIO
- Decimal representation of the binary value
representing the GPIO pins. 0 – 255 are valid.
Example: GPIO 46
Sets pins 7, 4, 3, and 2 to logic high(1) 5 V output if
these pins are configured as output pins using
GPIO:DIRection command (See “Table 9” to convert the
binary representation). Refer to section “3.13Digital
I/O” for more details.
GPIO?
Description: Queries the voltage levels 1 (5 V) or 0 (0 V) of digital
I/O input pins. Output pins return 0.
Query: GPIO?
Return String: 130
Pins 9 and 2 have 5 V input if these pins are configured
as input pins using GPIO:DIRection command (See
“Table 9” to convert the binary representation). Refer to
section “3.13Digital I/O” for more details.
Format:
GPIO:DIRection
Description: Configures the digital I/O pins as inputs or outputs.
Syntax: GPIO
- Decimal representation of the binary value
representing the GPIO pins. 0 – 255 are valid. Binary
value of 1 is output and 0 is input.
Example: GPIO:DIR 82
Sets pins 8, 6, and 2 as outputs and the rest as inputs
(See “Table 9” to convert the binary representation).
Refer to section “3.13Digital I/O” for more details.
GPIO:DIRection?
Description: Queries the digital I/O pins as outputs or inputs.Binary
value of 1 is output and 0 is input.
