The basic principle of a/D conversionThe analog signals are sampled in a series of selected moments, then the sampled values are converted to the output digital quantities, and the conversion results are given in a certain encoding format.The whole

Here, let me discuss the problem of using __delay_cycles delay for MSP430 MCU.The IAR for MSP430 compiler provides a compiler inline precision delay function (not a truefunction) to provide the user with a precise delay, the function prototype
