M5_PbHub

Simple library for the M5Stack PbHUB v1.1.

PbHub back

PbHub connected to KEY, LIGHT, PIR and ANGLE units

Usage

Code to add to global space (i.e. before setup() )

#include <M5_PbHub.h>
M5_PbHub myPbHub;

Code to add to setup()

Make sure to start Wire if you did not yet:

Wire.begin();

The following line of code must be added to setup():

myPbHub.begin();

The following line of code must be added to setup():

myPbHub.begin();

If a unit with pixels is connected to the PbHUB, you should initialize the pixel count immediatly aftewards:

myPbHub.setPixelCount( uint8_t channel ,  uint16_t count );

Code within loop()

Gets the digital value (0 or 1) of the I pin for the indicated channel :

int value = myPbHub.digitalRead(uint8_t channel);

Writes a digital value (0 or 1) to the O pin for the indicated channel :

myPbHub.digitalWrite(uint8_t channel, uint8_t  value);

Gets the analog value of the I pin for the indicated channel :

int value = myPbHub.analogRead(uint8_t channel);

Sets the PWM of to the O pin for the indicated channel :

myPbHub.analogWrite(uint8_t channel, uint8_t pin, uint8_t  pwm);

Sets the r,g,b color of the pixel specified at that index for the indicated channel :

myPbHub.setPixelColor(uint8_t channel, uint16_t index, uint8_t r,int8_t g, uint8_t b);

Starting from the index, sets a certain count of pixels to the same r,g,b color on the indicated channel :

myPbHub.fillPixelColor(uint8_t channel, uint16_t start, uint16_t index, uint8_t r,int8_t g, uint8_t b);
