PWM click is a simple solution for controlling 16 PWM outputs through a single I2C interface. The click board carries the PCA9685PW IC. It is designed to use either a 3.3V or 5V power supply. The board also uses a LOW Output Enable Input pin (OE), which is in place of the default mikroBUS RST pin.

Library Description

The library covers all the necessary functions that enables the usage of the PWM click board. It initializes and defines the I2C driver and drivers that offer a choice for controlling 16 PWM outputs through a single I2C interface. This library offer functions that allow the user to make controlled PWM output to each and every of 16 channels. It also allows for different configurations and prescaling. Library also offers generic read and write functions for aditional functionality.

Key functions:

  • pwm_devConfig( uint8_t allcall, uint8_t sub3, uint8_t sub2, uint8_t sub1, uint8_t sleep, uint8_t restart ) - Function is used to configure the device.
  • pwm_setChannel( uint8_t channId, uint8_t offset, uint8_t dutyCyc ) - Function is used to specific set channel output with data.
  • pwm_setAll( uint8_t dutyCyc ) - Function is used to set all channels output with data.

Examples description

The application is composed of the three sections :

  • System Initialization - Initializes GPIO, I2C and LOG structures, set RST pin as output.
  • Application Initialization - Initalizes I2C driver, enables output, configures device, sets prescaling, configures output and makes an initial log.
  • Application Task - (code snippet) - This is an example that shows some of the functions that PWM click has.
void applicationTask()
{
    uint16_t rawDc;
    uint8_t channId;
    uint8_t dutyCycle;
    channId = 0;
    mikrobus_logWrite( "Channel 0 false state  ", _LOG_LINE );
    pwm_channelState( channId, 0 );
    mikrobus_logWrite( "--------------------------", _LOG_LINE );
    Delay_ms( 2000 );
    
    mikrobus_logWrite( "Channel 0 set raw  ", _LOG_LINE );
    for ( rawDc = 0; rawDc < PWM_MAX_RESOLUTION; rawDc += 256 )
    {
        pwm_setChannelRaw( channId, 0, rawDc );
        mikrobus_logWrite( " >", _LOG_TEXT );
        Delay_ms( 500 );
    }
    mikrobus_logWrite( "", _LOG_LINE );
    mikrobus_logWrite( "--------------------------", _LOG_LINE );
    Delay_ms( 1000 );
    
    mikrobus_logWrite( "Channel 0 set  ", _LOG_LINE );
    for ( dutyCycle = 0; dutyCycle < 100; dutyCycle += 10 )
    {
        pwm_setChannel( channId, 0, dutyCycle );
        mikrobus_logWrite( " >", _LOG_TEXT );
        Delay_ms( 500 );
    }
    mikrobus_logWrite( "", _LOG_LINE );
    mikrobus_logWrite( "--------------------------", _LOG_LINE );
    Delay_ms( 1000 );
    
    mikrobus_logWrite( "All Channels raw set  ", _LOG_LINE );
    for ( rawDc = 0; rawDc < PWM_MAX_RESOLUTION; rawDc += 256 )
    {
        pwm_setAllRaw( rawDc );
        mikrobus_logWrite( " >", _LOG_TEXT );
        Delay_ms( 500 );
    }
    mikrobus_logWrite( "", _LOG_LINE );
    mikrobus_logWrite( "--------------------------", _LOG_LINE );
    Delay_ms( 1000 );
    
    mikrobus_logWrite( "All Channels set  ", _LOG_LINE );
    for ( dutyCycle = 0; dutyCycle < 100; dutyCycle += 10 )
    {
        pwm_setAll( dutyCycle );
        mikrobus_logWrite( " >", _LOG_TEXT );
        Delay_ms( 500 );
    }
    mikrobus_logWrite( "", _LOG_LINE );
    mikrobus_logWrite( "--------------------------", _LOG_LINE );
    Delay_ms( 1000 );
    
    mikrobus_logWrite( "All Channels false state  ", _LOG_LINE );
    pwm_allChannState( 0 );
    mikrobus_logWrite( "--------------------------", _LOG_LINE );
    Delay_ms( 2000 );
}

  • I2C
  • UART

Additional notes and informations

Depending on the development board you are using, you may need USB UART clickUSB UART 2 click or RS232 click to connect to your PC, for development systems with no UART to USB interface available on the board. The terminal available in all MikroElektronika compilers, or any other terminal application of your choice, can be used to read the message.
