Hi,
Customer need to create a timer interrupt every 1mS.
In the attached timer code the MCU never exits the ISR.
How do I clear the timer B interrupt flag?
/*
* tick.c
*
*/
#include "tick.h"
#include "global.h"
#include <msp430.h>
/*
* TARGET MCU MSP430FR2355
* */
uint16_t tick = 0; /* 1mS tick counter */
/*
* @brief Initialise timer A
* @detail
*/
void init1mSTick(void)
{
TBCCTL0 = CCIE; // TBCCR0 interrupt enabled
TBCTL = TBSSEL_2 + CNTL_0 + MC_1 + ID_2; // 16 bit, SMCLK/4, upmode
TBR = 10000; // Counter register
}
/*
* @brief Get 1mS tick value
*
*/
uint16_t get1mSTick(void)
{
return tick;
}
/*
* @brief Timer B interrupt vector
*/
#pragma vector=TIMERB0_VECTOR
__interrupt void TIMERB1_ISR(void)
{
tick++; /* Count 1mS */
}
/*End*/
Thank you.
Regards,
