G24-L AT Commands Reference Manual

Data sending (vector example):

Client has a data bus with 8 bits and plans to implement some protocol over it. In this example 4 pins (pins

1-4) are used as an output and 4 pins (5-8) are used as input.

Example of code is as follows:

AT+MIOD=000001111,0

// Set IO pins 1-4 to be output level mode.

OK

AT+MIOD=11110000,1

// Set IO pins 5-8 to be input level mode.

OK

// Unnecessary, because by default all pins are input.

AT+MIOD?

// (Optional) Read the IO pin definitions to confirm correct settings.

+MIOD: 11110000

// Pins 1-4 output pins 5-8 input.

OK

// At this point the module is configured to control the logic values of

all pins.

AT+MIOC=00001111,00000011

// Write vector, 0x3 on pins 1-4.

OK

// (pins 1,2 high, pins 3,4 low).

AT+MIOC?

// Read the pins status.

+MIOC: 01000011

// Pins 1,2,7 show the logical value high.

OK

AT+MIOC=00001111,00000000

// Write vector 0x0 on pins 1-4.

OK

AT+MIOC?

// (Optional) read the pins status.

+MIOC: 01110000

// Pin 1-4 low, pins 5,6,7 show logical high.

OK
