[[File:~~media/image173~~zero3-img173.png|576x128px]]</li>

<li>First set the GPIO port to output mode, where the third parameter requires the serial number of the wPi corresponding to the input pin

</ol>

<li>If everything is normal, the received string will be displayed in the receiving box</li>

</ol>

<li>The SPI that can be used in 26pin is SPI1, and the corresponding device node is '''/dev/spidev1.1'''

[[File:~~media/image360~~zero3-img360.png|576x133px]]</li>

<li>Here is a demonstration to test the SPI1 interface through the '''w25q64''' module, first connect the w25q64 module to the SPI1 interface

<li>Then open the wiringOP APP on the desktop</li>

<li>Then click the '''SPI_TEST''' button to open the SPI test interface

[[File:~~media/image374~~zero3-img374.png|518x96px]]</li>

<li>Then select the spi device node in the upper left corner. If you directly test the onboard SPIFlash, then keep the default '''/dev/spidev0.0'''. If you connect the '''w25q64''' module to the 26pin spi1, then please select /dev '''/dev/spidev1.1'''

</div></li>

<li>Then click the '''OPEN''' button to initialize the SPI</li>

[[File:~~media/image376~~zero3-img376.png|295x168px]]

</ol>

<li>Then fill in the bytes that need to be sent, such as reading the ID information of the onboard SPIFlash, fill in the address 0x9f in data[0], and then click the '''TRANSFER''' button

[[File:~~media/image377~~zero3-img377.png|294x169px]]</li>

<li>Finally, the APP will display the read ID information of the onboard SPI Flash</li>

[[File:~~media/image378~~zero3-img378.png|299x217px]]

</ol>

<li>If it is to read the w25q64 module connected to 26pin SPI1, then the read ID information is shown in the figure below

[[File:~~media/image379~~zero3-img379.png|302x201px]]</li>

<li>The MANUFACTURER ID of the w25q64 module is EFh, and the Device ID is 4017h, corresponding to the value read above (h stands for hexadecimal)

[[File:~~media/image380~~zero3-img380.png|336x113px]]</li></ol>

</li>

<li>First open the wiringOP APP on the desktop

[[File:~~media/image360~~zero3-img360.png|576x133px]]</li>

<li>Then click the '''I2C_TEST''' button to open the i2c test interface

[[File:~~media/image381~~zero3-img381.png|506x110px]]</li>

<li>The i2c test interface of wiringOP is shown in the figure below. You can see that the default i2c is '''/dev/i2c-3''', so we don't need to re-select</li>

[[File:~~media/image382~~zero3-img382.png|353x159px]]

</ol>

<li>Then connect an i2c device to the 26pin i2c3 pin, here we take the ds1307 rtc module as an example

[[File:~~media/image186~~zero3-img186.png|121x103px]]</li>

{| class="wikitable" style="width:800px;"

apollo-p2:/ # '''i2cdetect -y 3'''

|}

[[File:~~media/image383~~zero3-img383.png|424x186px]]</li>

<li>Then set the address of i2c to 0x68 in wiringOP, and then click the '''OPEN''' button to open i2c3

[[File:~~media/image384~~zero3-img384.png|354x177px]]</li>

<li>The display after clicking the '''OPEN''' button to open i2c3 is as follows:

[[File:~~media/image385~~zero3-img385.png|355x171px]]</li>

<li>Then we test to write a value into the register of the rtc module, for example, write 0x55 to the 0x1c address

<li>We first set the address of the register to be written to 0x1c

[[File:~~media/image386~~zero3-img386.png|322x152px]]</li>

<li>Then set the value to be written to 0x55

[[File:~~media/image387~~zero3-img387.png|315x177px]]</li>

<li>Then click the '''WRITE BYTE''' button to execute the write action

[[File:~~media/image388~~zero3-img388.png|314x173px]]</li></ol>

</li>

<li>Then click the '''READ BYTE''' button to read the value of the 0x1c register, if it is displayed as 0x55, it means that the i2c read and write test has passed
