 * Project: uCos-II/View driver
 *
 * Description:
 *     This driver is ported to the SDK7A404 EVB and is intended to be
 *     used with uCos/View from Micrium and the SDK7A404 BSP.
 *
 * Notes on implementation:
 *     The OS_VIEW_BAUDRATE define in the header file only works with
 *     bit rates of 9600, 19200, 38400, 57600, and 115200. Using other
 *     rates will not work.
 *
 * Notes on resources used in this driver:
 *     This driver uses one UART and a timer. The UART can be selected
 *     by defining the UCOSUART macro as UART1, UART2, or UART3. The
 *     timer can be selected by defining the UCOSTIMER macro as TIMER1,
 *     TIMER2, or TIMER3. The interrupt driver must be initialized
 *     prior to this driver being used.
