A simple way to manage Servo engines regarding the NVIDIA Jetson Nano Developer system is hook up the Jetson Nano via I2C to a PWM drivers. Appears right here:

Background

The obvious are USB, basically the place you connect when you look at the mouse and keyboard. Additional three include concealed out within the headers from the panel.

We’ve discussed common Asynchronous Receiver-Transmitter (UARTs) before (certainly one of which is the serial console). The Jetson Nano has two, one from the J44 Serial slot header, and one in the J41 growth Header.

There are conditions for Serial Peripheral program (SPI) ports. Inside the default Nano graphics arrangement, the Jetson Nano won’t have SPI port accessibility. But these devices forest may be reconfigured for being able to access SPI through J41 growth Header. Within the Jetson Nano J41 Pinout, NVIDIA suggests position for just two SPI slots.

Note: it’s also possible to discover the J41 Expansion Header known as the GPIO Header. The two conditions were similar.

The rest of the serial slots is Inter-integrated Circuit (I2C). The Inter-integrated Circuit (I 2 C) method passes by different names according to whom you consult with, a€?I squared Ca€?, a€?we two Ca€? or a€?I we Ca€?. I2C is intended for short-distance interaction within just one tool. A primary reason that it’s well-liked by the creator crowd would be that it just needs two wires (the a€?dataa€? and a€?clocka€?) along with power and floor receive operating.

In order to control Servo engines, we make use of Pulse Width Modulation (PWM). The Jetson Nano has got the capacity for producing two PWM pulses on the J41 Header. However, you ought to reconfigure the product forest to manufacture these indicators available on Pins 32 and 33. An easier way is to use an external piece of components. Lees verder →
