r1410 r1414 2 2 \brief This is a standalone test program for serial communication between the 3 3 TelosB and a computer. 4 5 The MSP430 chip speaks 2-wire UART, i.e. one two pins are used: one for sending 6 bytes (UART1TX), one for receiving bytes (UART1RX). These pins are connected to 7 an FTDI "UART-to-USB" converted chip. When you plug the TelosB into your 8 computer, the FTDI driver install a virtual COM port. That is, when you 9 read/write to that port, the bytes end up on the UART1RX/UART1TX pins. 10 11 Connect your TelosB board to your computer, download this application to your 12 TelosB board and run it. On your computer, open a PuTTY client on the virtual 13 COM port of your board, and type characters into it. 14 15 Each time you type a character, you should see: 16 - the small green LED (RX) blinks. It's mounted on the RX line, so "shows" you 17 when a byte passes. 18 - the character prints on your terminal, as it is sent back on the TX line. 19 - the red LED toggles 20 - the smalll red LED (TX) blinks. It's mounted on the TX line, so "shows" you 21 when a byte passes. 22 23 Uncomment the BAUDRATE_115200 line below to switch from 9600baud to 115200baud. 4 24 5 25 The digital UART interface is: … … 7 27 - P3.7: UART1RX 8 28 9 \author Thomas Watteyne <watteyne@eecs.berkeley.edu>, August 201029 \author Thomas Watteyne <watteyne@eecs.berkeley.edu>, February 2012 10 30 */ 31 32 //#define BAUDRATE_115200 // uncomment this to communicate at 115200baud 11 33 12 34 #include "msp430f1611.h" … … 15 37 void main(void) 16 38 { 17 WDTCTL = WDTPW + WDTHOLD;// disable watchdog timer39 WDTCTL = WDTPW + WDTHOLD; // disable watchdog timer 18 40 19 DCOCTL = DCO0 | DCO1 | DCO2;// MCLK at ~8MHz20 BCSCTL1 = RSEL0 | RSEL1 | RSEL2;// MCLK at ~8MHz41 DCOCTL = DCO0 | DCO1 | DCO2; // MCLK at ~8MHz 42 BCSCTL1 = RSEL0 | RSEL1 | RSEL2; // MCLK at ~8MHz 21 43 // by default, ACLK from 32kHz XTAL which is running 22 23 P3SEL = 0xC0; // P3.6,7 = UART1TX/RX 44 P5DIR |= 0x70; // P5DIR = 0bx111xxxx for LEDs 45 P5OUT |= 0x70; // P2OUT = 0bx111xxxx, all LEDs off 46 47 P3SEL = 0xC0; // P3.6,7 = UART1TX/RX 24 48 25 //9600 baud, clocked from 32kHz ACLK 26 ME2 |= UTXE1 + URXE1; // enable UART1 TX/RX27 UCTL1 |= CHAR; // 8-bit character28 UTCTL1 |= SSEL0; // clocking from ACLK29 UBR01 = 0x03; // 32k/9600 - 3.4130 UBR11 = 0x00; //31 UMCTL1 = 0x4A; // modulation32 UCTL1 &= ~SWRST; // clear UART1 reset bit33 IE2 |= URXIE1; // enable UART1 RX interrupt34 35 __bis_SR_register(LPM3_bits + GIE); // sleep, leave interrupts and ACLK on36 37 /* 38 //115200 baud, clocked from 4.8MHz SMCLK39 ME2 |= UTXE1 + URXE1;// enable UART1 TX/RX40 UCTL1 |= CHAR;// 8-bit character41 UTCTL1 |= SSEL1; // clocking from SMCLK42 UBR01 = 41; // 4.8MHz/115200 - 41.6643 UBR11 = 0x00;//44 UMCTL1 = 0x4A;// modulation45 UCTL1 &= ~SWRST;// clear UART1 reset bit46 IE2 |= URXIE1;// enable UART1 RX interrupt47 48 __bis_SR_register(LPM0_bits + GIE); // sleep, leave interruptson49 */ 49 #ifdef BAUDRATE_115200 50 //115200 baud, clocked from 4.8MHz SMCLK 51 ME2 |= UTXE1 + URXE1; // enable UART1 TX/RX 52 UCTL1 |= CHAR; // 8-bit character 53 UTCTL1 |= SSEL1; // clocking from SMCLK 54 UBR01 = 41; // 4.8MHz/115200 - 41.66 55 UBR11 = 0x00; // 56 UMCTL1 = 0x4A; // modulation 57 UCTL1 &= ~SWRST; // clear UART1 reset bit 58 IE2 |= URXIE1; // enable UART1 RX interrupt 59 60 __bis_SR_register(LPM0_bits + GIE); // sleep, leave interrupts on 61 #else 62 //9600 baud, clocked from 32kHz ACLK 63 ME2 |= UTXE1 + URXE1; // enable UART1 TX/RX 64 UCTL1 |= CHAR; // 8-bit character 65 UTCTL1 |= SSEL0; // clocking from ACLK 66 UBR01 = 0x03; // 32768/9600 = 3.41 67 UBR11 = 0x00; // 68 UMCTL1 = 0x4A; // modulation 69 UCTL1 &= ~SWRST; // clear UART1 reset bit 70 IE2 |= URXIE1; // enable UART1 RX interrupt 71 72 __bis_SR_register(LPM3_bits + GIE); // sleep, leave interrupts and ACLK on 73 #endif 50 74 } 51 75 … … 53 77 __interrupt void uart_ISR(void) 54 78 { 55 U1TXBUF = U1RXBUF;// TX -> RXed character56 P5OUT ^= 0x10;// toggle LED79 U1TXBUF = U1RXBUF; // TX -> RXed character 80 P5OUT ^= 0x10; // toggle LED 57 81 } -
