dsc_dac_basic

dsc_dac_basic#

Overview#

The dsc_dac basic example shows how to use DAC module simply as the general DAC converter.

When the DAC’s synchronous conversion mode is not selected, when the digital value is written to the DAC’s buffered data register, the data can be immediately presented to the DAC and converted to an analog output. The DAC output voltage can be measured on DAC output pin.

Supported Boards#

MC56F81000-EVK
Hardware requirements

  • 2 x Micro USB cable

  • MC56F81000-EVK board

  • Personal Computer

  • Multimeter

Board hardware common setting

  1. Power setting:

    Connect J8 pin2 and pin3 Connect J5 pin1 and pin2 Connect J6 pin1 and pin2

  2. Onboard PnE U-MultiLink debugger setting:

    Connet J11 pin2 and pin3 Connect J13 pin 1-2, 3-4, 5-6, 7-8, to setup onboard debugger PnE U-MultiLink. Note: when use external debugger(connected to J10), leave all J13 pins open.

Board settings

No special settings are required.

Prepare the Demo

  1. Connect USB cable between the host PC and the USB(J26) port on the target board to setup USB to UART bridge.

  2. Connect USB cable between the host PC and the USB(J12) port on the target baord to setup mulitlink debugger.

  3. Open a serial terminal with the following settings:

    • 115200 baud rate

    • 8 data bits

    • No parity

    • One stop bit

    • No flow control

  4. Download the program to the target board with PnE U-MultiLink debug configuration.

  5. Either press the reset button on your board or launch the debugger in your IDE to begin running the demo. Please be noted default FCF(flash configuration field) makes the MCU boot from flash.

Running the demo

When the demo runs successfully, the log would be seen on the terminal like:

DAC basic Example.

Please input a value (0 - 4095) to output with DAC:

Then change DAC value, and measure the voltage of DACA output pin(TP1). Use a multimeter to measure the voltage of TP1, then you will get the voltage of DAC output. (Each DAC LSB represents 0.806 mV).

MC56F83000-EVK
Hardware requirements

  • Micro USB cable

  • MC56F83000-EVK board

  • Personal Computer

  • Multimeter

Board hardware common setting

  1. Power setting:

    Connect J19 pin2 and pin3 Connect J12 pin1 and pin2 Connect J13 pin1 and pin2 Connect J15 pin1 and pin2 Connect J16 pin2 and pin3 Connect J17 pin1 and pin2

  2. Onboard OSJTAG debugger setting:

    Leave J5 open Leave J6 open Note: J6 is only used(connected) when firmware update for onboard debugger OSJTAG. Connect J11 pin 1-2, 3-4, 5-6, 7-8, to setup onboard debugger OSJTAG. Note: when use external debugger(connected to J10), leave all J11 pins open.

Board settings

No special settings are required.

Prepare the Demo

  1. Connect USB cable between the host PC and the JM60 USB(J8) port on the target board. It setups OSJTAG and COM port in PC device manager.

  2. Open a serial terminal with the following settings:

    • 115200 baud rate

    • 8 data bits

    • No parity

    • One stop bit

    • No flow control

  3. Download the program to the target board with OSJTAG debug configuration.

  4. Either press the reset button on your board or launch the debugger in your IDE to begin running the demo. Please be noted that default FCF(flash configuration field) setting makes MCU boot from bootloader. So after reset button press, it will wait 5s(wait in bootloader) to run the application code.

Running the demo

When the demo runs successfully, the log would be seen on the terminal like:

DAC basic Example.

Please input a value (0 - 4095) to output with DAC:

Then change DAC value, and measure the voltage of DACA output pin(TP9). Use a multimeter to measure the voltage of TP9, then you will get the voltage of DAC output. (Each DAC LSB represents 0.806 mV).

  • Personal Computer

  • Multimeter

Board hardware common setting

  1. HW reworkd(workaround):

    Connect J18(the mini USB port) pin4 and pin5. Note: This is due to HW design error, correct setting should be: J18 pin4 left empty and pin5 connected GND.

  2. Power setting:

    Connect J11 pin1 and pin2 Connect J6 pin1 and J7 pin2

  3. UART setting:

    Connect J8 pin3 and pin4 Connect J9 pin3 and pin4
