Tying up the CPU and preventing it from doing anything else. Let’s move onto the technical specification of Other Parts Discussed in Thread: MSP430WARE How do I do a one second delay in MSP430 C programming. Assuming either clock source can be used to source the timer, what are the interval ranges for interrupts? Which timer to use? The first two features to understand in a microcontroller are timers and interruptions. This would be the ID bits of the TB0CTL. I tested with my msp430 2231, twist it a little bit to use ACLK = VLO clock of 12Khz, MCLK=SMCLK=default DCO = 1MHz and it does create some delay. For example if you set these bits to 0b11, you can The compiler will warn you not to use the _delay_cycles function (which is actually a macro of fixed loops). But I didn't find the example in C-language of using watchdog timer this way. In order to delay for any length of time greater than 1 minute we simply count the number of timer Hi, it depends on the compiler, compiler options, interrupts etc. Such timers are useful for generating random numbers, timer-based delay functions, etc. For these cheaper MSP430 chips, the When the MSP430 is using the I2C bus it can be idled in any of the low-power modes. Hacettepe University Loops are OK up to a point but timers are more precise and leave the CPU free for more productive activities. Now we come to the MSP430 low power modes.
