Click library

  • Author : Stefan Ilic
  • Date : Aug 2021.
  • Type : I2C/SPI type

Software Support

We provide a library for the Charger11 Click as well as a demo application (example), developed using MikroElektronika compilers. The demo can run on all the main MikroElektronika development boards.

Package can be downloaded/installed directly from NECTO Studio Package Manager(recommended way), downloaded from our LibStock™ or found on Mikroe github account.

Library Description

This library contains API for Charger11 Click driver.

Standard key functions :

  • charger11_cfg_setup Config Object Initialization function.

    void charger11_cfg_setup ( charger11_cfg_t *cfg );
  • charger11_init Initialization function.

    err_t charger11_init ( charger11_t *ctx, charger11_cfg_t *cfg );

Example key functions :

  • charger11_spi_increment_wiper Charger 11 incrementing wiper position.

    void charger11_spi_increment_wiper( charger11_t *ctx );
  • charger11_spi_decrement_wiper Charger 11 decrementing wiper position.

    void charger11_spi_decrement_wiper( charger11_t *ctx );
  • charger11_i2c_get_volt Charger 11 getting output voltage.

    float charger11_i2c_get_volt( charger11_t *ctx, float reference_voltage );

Example Description

This is an example that demonstrates the use of the Charger 11 Click board.

The demo application is composed of two sections :

Application Init

Initalizes INT ( ST ), PWM ( LG ), AN ( LR ) pins and SPI, I2C, LOG modules.


void application_init ( void ) {
    log_cfg_t log_cfg;  /**< Logger config object. */
    charger11_cfg_t charger11_cfg;  /**< Click config object. */

    /** 
     * Logger initialization.
     * Default baud rate: 115200
     * Default log level: LOG_LEVEL_DEBUG
     * @note If USB_UART_RX and USB_UART_TX 
     * are defined as HAL_PIN_NC, you will 
     * need to define them manually for log to work. 
     * See @b LOG_MAP_USB_UART macro definition for detailed explanation.
     */
    LOG_MAP_USB_UART( log_cfg );
    log_init( &logger, &log_cfg );
    log_info( &logger, " Application Init " );

    // Click initialization.
    charger11_cfg_setup( &charger11_cfg );
    CHARGER11_MAP_MIKROBUS( charger11_cfg, MIKROBUS_1 );
    err_t init_flag  = charger11_init( &charger11, &charger11_cfg );
    if ( ( I2C_MASTER_ERROR == init_flag ) || ( SPI_MASTER_ERROR == init_flag ) ) {
        log_error( &logger, " Application Init Error. " );
        log_info( &logger, " Please, run program again... " );

        for ( ; ; );
    }

    log_info( &logger, " Application Task " );
    charger11_case_report( &charger11 );
}

Application Task

Waits for user input in order to increment, decrement wiper or log report (Wiper position and Output voltage)


void application_task ( void ) {
    char uart_char;
    if ( log_read( &logger, &uart_char, 1 ) ) {
        switch (uart_char) {
            case '+' : {
                charger11_case_plus( &charger11 );
                break;
            }
            case '-' : {
                charger11_case_minus( &charger11 );
                break;
            }
            case 'r' : {
                charger11_case_report( &charger11 );
                break;
            }
            default : {
                log_printf( &logger, "> Invalid command \r\n" );
                break;
            }
        }
    }
}

The full application code, and ready to use projects can be installed directly from NECTO Studio Package Manager(recommended way), downloaded from our LibStock™ or found on Mikroe github account.

Other Mikroe Libraries used in the example:

  • MikroSDK.Board
  • MikroSDK.Log
  • Click.Charger11

Additional notes and informations

Depending on the development board you are using, you may need USB UART Click, USB UART 2 Click or RS232 Click to connect to your PC, for development systems with no UART to USB interface available on the board. UART terminal is available in all MikroElektronika compilers.

ROTARY O Click

0

Rotary Click carries a 15-pulse incremental rotary encoder with detents, surrounded by a ring of 16 orange LEDs. It’s a perfect solution for adding a precision input knob to your design. The encoder outputs A and B signals (out of phase to each other); the knob also acts as a push-button which sends an interrupt to the target board MCU. The LED ring is controlled through SPI lines (CS, SCK, MISO, MOSI). Rotary Click can be used with either a 3.3V or 5V power supply.

PWM Click

1

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.

I2C to CAN Click

0

I2C to CAN Click is a compact add-on board that contains I2C to CAN-physical transceiver, which extends a single-master I2C bus through harsh or noisy environments. This board features the LT3960, a robust high-speed transceiver that extends a single-master I2C bus up to 400kbps using the CAN-physical layer from Analog Devices. One LT3960 from SCL and SDA I2C lines creates equivalent differential buses (CAN) on two twisted pairs, while the second LT3960 recreates the I2C bus locally for any slave I2C devices on the other end of the twisted pairs. A built-in 3.3V LDO powers both the I2C and CAN lines from a single input supply from 4V to 60V. This Click board™ is suitable for industrial and automotive networking, remote sensor applications, and more.
