MiZ702 Study notes 9--XADC capture on-chip data PS version

This time with Zynq's embedded XADC to collect some parameters inside the ZYNQ:

vccint: Internal PL Core Voltage

vccaux: Auxiliary PL voltage

VREFP:XADC Positive Reference voltage

VREFN:XADC Negative Reference voltage

VCCBRAM:PL Bram Voltage

Vccpint:ps Internal Core voltage

Vccpaux:ps Auxiliary Voltage

Operating voltage of VCCDDR:DDR RAM

This process and the development process of the previous indistinguishable, I hope you can fully familiar with the process ~ ~

As always, create a block Design and add the Zynq kernel and the XADC IP to it.

Setting the XADC Core

Execute these two items in turn:

After execution as shown:

Execute generate Output products and Create HDL Wrapper in turn

The final compilation until a bit file is generated.

Export the hardware and open the SDK via Vivado.

Enter the SDK, how to create a new project, do not re-verbose, please refer to the previous section. After you create a new MAIN.C, add the following code as follows ~ ~ (This code is a reference to a foreign God, Adam wrote, Tribute to the Great God ~ ~)

1. Use the "xadcps_selftest ()" This self-test is needless to say.

2. Use "Xadcps_setsequencermode ()" This is to set the sampling mode.

3. Use "Xadcps_setalarmenables ()" This is set sampling value alarm, direct shutdown, do not need to alarm

4. Use "Xadcps_setseqinputmode ()" This is the setting of the input mode

5. Use "Xadcps_setseqchenables () This is the Enable sampling channel

After compiling, remember to download the bit file ~ ~ Connected to the serial port, then you can execute the program:

Thus, by opening the serial debugging assistant, you can see the print out the following information ~ ~

New Year's Day ~ ~ from this article, Vivado upgrade to version 2015.2 ~ ~ If you need to download, the network address is as follows ~ ~
