FTDI Click is a compact add-on board that provides a high-speed USB to a serial interface converter. This board features the FT2232H, a 5th-generation high-speed USB 2.0 to a serial UART/I2C/SPI interface converter from FTDI. The entire USB protocol is handled on the chip (FTDI USB drivers required), making this board ideal for various USB applications. Besides a selectable interface and a standalone operation possibility, it also includes an EEPROM which contains the USB configuration descriptors for the FT2232H and one DA converter for additional reference in user-configurable applications.

Click library

  • Author : Stefan Filipovic
  • Date : Feb 2024.
  • Type : UART type

Software Support

We provide a library for the FTDI 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 FTDI Click driver.

Standard key functions :

  • ftdi_cfg_setup Config Object Initialization function.

    void ftdi_cfg_setup ( ftdi_cfg_t *cfg );
  • ftdi_init Initialization function.

    err_t ftdi_init ( ftdi_t *ctx, ftdi_cfg_t *cfg );

Example key functions :

  • ftdi_generic_write This function writes a desired number of data bytes by using UART serial interface.

    err_t ftdi_generic_write ( ftdi_t *ctx, uint8_t *data_in, uint16_t len );
  • ftdi_generic_read This function reads a desired number of data bytes by using UART serial interface.

    err_t ftdi_generic_read ( ftdi_t *ctx, uint8_t *data_out, uint16_t len );

Example Description

This example demonstrates the use of FTDI Click by echoing back all the received messages.

The demo application is composed of two sections :

Application Init

Initializes the driver and logger.


void application_init ( void )
{
    log_cfg_t log_cfg;  /**< Logger config object. */
    ftdi_cfg_t ftdi_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.
    ftdi_cfg_setup( &ftdi_cfg );
    FTDI_MAP_MIKROBUS( ftdi_cfg, MIKROBUS_1 );
    if ( UART_ERROR == ftdi_init( &ftdi, &ftdi_cfg ) ) 
    {
        log_error( &logger, " Communication init." );
        for ( ; ; );
    }

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

Application Task

Any data which the host PC sends to the Virtual COM Port (for example, typed into the terminal window in UART Terminal) will be sent over USB to the Click board and then it will be read and echoed back by the MCU to the PC where the terminal program will display it. The data will also be displayed on the USB UART.

void application_task ( void )
{
    uint8_t rx_data = 0;
    if ( ftdi_generic_read ( &ftdi, &rx_data, 1 ) > 0 )
    {
        ftdi_generic_write ( &ftdi, &rx_data, 1 );
        log_printf( &logger, "%c", rx_data );
    }
}

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.FTDI

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.

DC Motor 13 Click

0

DC Motor 13 Click is a compact add-on board with a brushed DC motor driver. This board features the TB67H481FNG, a dual-channel, H-bridge, brushed DC motor driver from Toshiba Semiconductor that uses the PWM IN interface to control the DC motor outputs. Fabricated with the BiCD process (DMOSFET is used for output power transistor), it covers a wide operating voltage range of 8.2V to 44V with a maximum output current capacity of 2A. It also offers helpful features like a robust and reliable operation, like the decay modes selection function, PWM constant-current drive, torque settings, protection features, and one anomaly detection indicator.

Stepper 10 Click is a two-phase bipolar stepping motor driver capable of controlling one stepper motor with PWM constant current drive. Click's featured chip TB67S128FTG, from Toshiba Semiconductor, fabricated with BiCD process with an output rating of 50V/5A and a built-in decoder can supply the motor with voltage of up to 44V. Toshiba's innovative technology process results in low-power consumption with low on-resistance (0.25Ω) on the integrated MOSFET output stage. The stepper motor can be driven in both directions from full step to 1/128 micro-steps.
