How to Install Cypress Semiconductor USB to Serial Driver on Ubuntu
Cypress Semiconductor USB to Serial Bridge Controllers are devices that provide configurable serial channels for UART/I2C/SPI interfaces with low power consumption. They are compatible with Windows, Mac OS X and Linux operating systems. In this article, we will show you how to install the Cypress Semiconductor USB to Serial driver on Ubuntu Linux.
Step 1: Download the USB-Serial Software Development Kit
The USB-Serial Software Development Kit (SDK) contains the Windows software library with examples, Windows host driver, Configuration Utility and related documentation. You can download it from the Cypress Webpage.[^1^]
Step 2: Extract the SDK files
After downloading the SDK installer file, you need to extract it to a folder on your computer. You can use any archive manager tool such as 7-Zip or WinRAR to do this. You should see a folder named \"USB-Serial SDK\" with several subfolders inside.
Step 3: Install the Linux driver
The Linux driver for the Cypress Semiconductor USB to Serial Bridge Controllers is located in the \"Linux\" subfolder of the SDK. To install it, you need to open a terminal window and navigate to the \"Linux\" subfolder. Then, you need to run the following commands:
The first command copies the driver file to the appropriate location in your system. The second command updates the module dependency information. The third command loads the driver module into the kernel.
Step 4: Connect your device and test it
Now you can connect your Cypress Semiconductor USB to Serial device to your computer using a USB cable. You should see a message in your terminal window indicating that the device has been detected and assigned a serial port name such as /dev/ttyUSB0. You can use any serial terminal application such as minicom or screen to communicate with your device. For example, you can run the following command to open a serial terminal with 115200 baud rate:
screen /dev/ttyUSB0 115200
You can then type commands or send data to your device and see the responses on your screen. To exit the screen session, press Ctrl+A followed by Ctrl+\\\\.
In this article, we have shown you how to install the Cypress Semiconductor USB to Serial driver on Ubuntu Linux. This driver allows you to use your Cypress Semiconductor USB to Serial device with various serial interfaces such as UART, I2C and SPI. We hope this article was helpful and informative for you.
What are UART, I2C and SPI
UART, I2C and SPI are different types of serial interfaces that allow devices to communicate with each other. Serial interfaces use a single or a few wires to transmit data bits one by one, as opposed to parallel interfaces that use multiple wires to transmit data bits simultaneously. Serial interfaces have the advantage of being simpler, cheaper and more reliable than parallel interfaces, but they also have the disadvantage of being slower and having limited distance.
UART stands for Universal Asynchronous Receiver/Transmitter. It is a simple and widely used serial interface that uses two wires: one for transmitting data (TX) and one for receiving data (RX). UART does not have a clock signal to synchronize the data transmission, so both devices need to agree on the same baud rate (the number of bits per second) and the same data format (the number of data bits, parity bits and stop bits). UART is suitable for point-to-point communication between two devices over short distances.
I2C stands for Inter-Integrated Circuit. It is a more complex and versatile serial interface that uses two wires: one for a clock signal (SCL) and one for data (SDA). I2C allows multiple devices to share the same bus and communicate with each other using addresses. I2C has a master-slave architecture, where the master device initiates and controls the communication with the slave devices. I2C is suitable for connecting low-speed peripherals such as sensors, EEPROMs and LCDs to a microcontroller over short distances.
SPI stands for Serial Peripheral Interface. It is another complex and versatile serial interface that uses four wires: one for a clock signal (SCK), one for data from master to slave (MOSI), one for data from slave to master (MISO) and one for chip select (CS). SPI allows full-duplex communication between a master device and one or more slave devices. SPI has a master-slave architecture, where the master device generates the clock signal and selects the slave device to communicate with using the CS wire. SPI is suitable for connecting high-speed peripherals such as flash memory, SD cards and ADCs to a microcontroller over short distances. a474f39169
