Please note in the image below, the configuration of Termite is shown for communicating with this example code. Consult Silicon Labs support if help is needed.
#CP210X USB TO UART BRIDGE ARDUINO DRIVER#
Driver installation will vary system to system but often only involves a simple installer utility. These can be downloaded directly from Silicon Labs or local but older versions for Windows, Mac, or Linux (3.x.x).
#CP210X USB TO UART BRIDGE ARDUINO INSTALL#
Additionally, most operating system installs will need to download and install a driver for the CP210x family of USB to UART devices. Termite is a versatile tool allowing for display and entry of both ASCII characters and raw hex values. One suggested program for Windows based systems is Termite ( Local Copy).
#CP210X USB TO UART BRIDGE ARDUINO SERIAL#
To be able to fully use a serial (UART) port on a computer a 'terminal program' should be employed. If you have one of these platforms, download the loader from the Teensy 2.0 website and program the hex that way. The Makefile does not currently support download automatically to Linux or Mac machines. #CP210X USB TO UART BRIDGE ARDUINO CODE#
The sample code can be compiled from the command-line via the command 'make all' and downloaded to a Teensy 2.0 with the command 'make program' in windows. As an example, the user can enter a letter back to the Teensy over the serial port and see a change in response.ĬP210x USB to UART Teensy 2.0 Sample Code 
The protocol is set up for 8 data bits, no parity, and one stop bit (8N1). The code initializes the hardware UART on the Teensy 2.0 and transmits "Hello World" repeatedly over the UART port at a baudrate of 34800. There is a cp210x.h and cp210x.c file included in the example. You may need to install the avr-gcc compiler
This code is tested to compile via avr-gcc under Windows and Linux.
After wiring the unit, you can download the C example code below. Finally since the CP210x module will power the Teensy, connect the 5V pin of the CP210x to the 5V pin of the Teensy 2.0. The receive (RXD) of the microcontroller then goes to the transmit (TX) pin of the CP2012. Be aware that when using UART serial, the transmit (TXD) pin of the microcontroller should be connected to the receive (RX) pin of the CP2102. The Teensy 2.0 has two dedicated UART serial pins located on PORT D, pins 2 and 3. Common grounds must always be used for communication systems to allow for reliable signal transfer. To wire the system, connect a common ground between the CP210x module and the Teensy 2.0. For this example the CP210x module will be used to power the Teensy 2.0 at 5V after programming. Both outputs are only rated of low currents (less than 100mA) but it can be very useful for powering a small system from a USB port. Unique to this PCB implementation of the CP2102 is both a 5V and 3.3V output. This example will detail the wiring for a Teensy 2.0 microcontroller. Wiring: The CP210c module can be connected either a 5V or 3.3V logic level UART serial port. CP2102 with other USB-UART adapter circuit works similar to the PC through the driver's USB port into a virtual COM port in order to achieve the purpose of expansion. tiny26 Microcontroller Board (tiny26.1)ĬP2102 its high integration, built-in USB2.0 full-speed function controller, USB transceiver, crystal oscillator, EEPROM, and asynchronous serial data bus (UART), supports full-featured modem signals, without any external USB device.
