Hi, I use "uart_pc_echo_12mhz" and when I run this program i don't recive any data in putty, and how to change this program to receive a string of data in integer form (1,2,3,4,5,6)?
I have RXD and TXD plugin in my board.
Code for "uart_pc_echo_12mhz" is:
/****************************************************************************** * MSP432 UART - PC Echo with 12MHz BRCLK * * Description: This demo echoes back characters received via a PC serial port. * SMCLK/DCO is used as a clock source and the device is put in LPM0 * The auto-clock enable feature is used by the eUSCI and SMCLK is turned off * when the UART is idle and turned on when a receive edge is detected. * Note that level shifter hardware is needed to shift between RS232 and MSP * voltage levels. * * MSP432P401 * ----------------- * | | * | | * | | * RST -| P1.3/UCA0TXD|----> PC (echo) * | | * | | * | P1.2/UCA0RXD|<---- PC * | | * * Author: Timothy Logan *******************************************************************************/ /* DriverLib Includes */ #include "driverlib.h" /* Standard Includes */ #include <stdint.h> #include <stdbool.h> /* UART Configuration Parameter.
