Học MSP430 với Kit MSP430 LaunchPad - Bài 4: Timer/Counter. I have written this code: When the MSP430 is using the I2C bus it can be idled in any of the low-power modes. Do not leave it in a register. t. You are probably missing an environment-specific inlcude that sets/defines 'DCO_FREQ'. There is a very early llvm-msp430 project, which may eventually provide better support for MSP430 in LLVM . If applied to two signals, let's call them A and B, we have this truth table: Mar 15, 2016 · The assembly code needs to follow the rules of the C compiler's calling convention, which is given on page 130 of MSP430 Optimizing C/C++ Compiler User's Guide.

For the delay, as a TI employee said, we use our own function to manipulate delays. The program counter on the MSP430 is register R0; stack pointer: points to the address where the last value pushed on the stack is stored Assembly code for a simple 2-digit hex counter written in Code Composer Studio to run on the MSP430 microcontroller. After declaring our variables, we stop the watchdog timer. Timers of any microcontroller are Aug 11, 2015 · Vyacheslav, you're right, there is no example for it in the given code examples for the processor.
