USB UART 4 click PID MIKROE-2810 Weight 23 g USB UART 4 click features well-known FT232RL USB-to-UART interface module from FDTI. It provides USB to asynchronous serial data transfer interface, allowing the microcontroller based designs to communicate with the personal computer, in a very simple way. FT232RL is a very popular USB to UART interface IC, used on many MikroElektronika devices, both for its reliability and simplicity. USB UART 4 click is used for whenever there is a need to seamlessly and effortlessly interface the UART lines to a personal computer. It can be used with the UART terminal, found in MikroElektronika compilers. How does it work? The entire USB protocol is handled on the module, thus no USB specific firmware programming is required. FTDI provides royalty-free Virtual Com Port VCP and Direct D2XX drivers for all the major OSes, used on personal computers. FT232RL contains integrated 1024 Bit internal EEPROM for storing USB VID, PID, serial number, product description strings and CBUS I/O configuration. The Baud Rate Generator provides a 16x clock input to the UART Controller from the 48MHz reference clock. It consists of a 14 bit pre-scaler and 3 register bits which provide fine tuning of the baudrate - used to divide by a number plus a fraction. This determines the baud rate of the UART, which is programmable from 183 baud to 3 Mbaud. Also non-standard baud rates are supported. The baud rate is automatically calculated by the FTDI driver, so it is enough to simply forward the desired baudrate to the driver, usually done by selecting the baudrate via the OS terminal application. After installing the OS drivers, device is ready to be used. When plugged in, it will create a virtual COM port. Then, it can be used with the USART Terminal application, included in every mikroE compiler, for the data exchange between the MCU and the host computer, via the UART pins of the click board. More information about working with the UART communication in general can be found in the following Learn article. This device also features the configurable CBUS pins, which can be used for several different useful functions, as for example - configurable clock out for driving the microcontroller, data LED drive, USB Sleep, PWR status and so on. By default, CBUS3 and CBUS4 pins are configured as Power Enable and Sleep options and are routed to the PWR and SLP pins of the mikroBUS . More information about configuring the CBUS pins can be found in the FT232RL datasheet. SLP output pin will be set to a LOW logic state during the USB suspend mode It can be used to power down external circuitry or be used for similar purposes. PWR output pin will be set to a LOW logic state, after the device has been configured by the USB, then HIGH during the USB suspend mode.
