Part Number: MSP430FR2355

Tool/software: Code Composer Studio

supoose i am using adc12 and dac on the same board.i want to operate both of them in the fastest possible speed.

  • Hello,

    It is possible to use both of these HW modules on the same board. You can find code examples in the TI Resource Explorer showing how to properly use both the ADC12 and the DAC peripherals.

    Best regards,

  • i want to operate both of them in maximum speed how can i do it?

  • Hello,

    The DAC output is updated when a new value is written to the DACDAT register. Controlling the speed of how often the DAC is updated is based on you and your software. The only thing to keep in mind is the DAC update period must be longer than the setup time. Otherwise, the output may distort upon the update frequency overhead. Please refer to the SAC DAC section in the user's guide for more information on this.

    The ADC max speed is specified as 200ksps maximum conversion rate. This sampling rate is based on the clock signal you feed into the ADC module and how often you trigger a conversion. Again you can refer to the user's guide for a complete explanation of how to use the peripheral.

    Best regards,

    Matt
