For usage examples, see the

https://python-periphery.readthedocs.io/en/latest/pwm.html

I2C

The following code shows how to instantiate each of the I2C ports with Periphery:

i2c2 = I2C(

"/dev/i2c-1"

)

i2c3 = I2C(

"/dev/i2c-2"

)

For usage examples, see the

https://python-periphery.readthedocs.io/en/latest/i2c.html

SPI

The following code shows how to instantiate each of the SPI ports with Periphery:

# SPI1, SS0, Mode 0, 10MHz

spi1_0 = SPI(

"/dev/spidev32766.0"

10000000

)

# SPI1, SS1, Mode 0, 10MHz

spi1_1 = SPI(

"/dev/spidev32766.1"

10000000

)

For usage examples, see the

https://python-periphery.readthedocs.io/en/latest/spi.html

UART

The following code shows how to instantiate each of the UART ports with Periphery:

# UART1, 115200 baud

uart1 = Serial(

"/dev/ttymxc0"

115200

)

# UART3, 9600 baud

uart3 = Serial(

"/dev/ttymxc2"

9600

)

Caution:

UART1 is shared with the Linux serial console. To use the UART1 port in your application, you

must disable the serial console with the following command:

systemctl stop [email protected]

Note: UART3 is not enabled by default in Mendel 3.0 (Chef), but we've released a package update to
enable it. First check to see if it's available on your board:

/dev |

grep

ttymxc

If you see

ttymxc2

listed, then you're all good. If not, then you need to update as follows:

sudo

apt-get

update

sudo

apt-get

dist-upgrade

sudo

reboot

now
