Teensy driver 2.0 serial#
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.

I believe I've have the correct ftdi drivers installed, openocd was built with these added into the configure file. I've gone through some of the other threads and followed up on those suggestions. Warn : Unable to open FTDI Device tried: 'libftd2xx' and 'libftd2xx A' cfg file (refer below) but get the following error messages when running openocd: Right now I'm working with my own paired down. I've run into problems getting openocd to communicate with the Teensy++2. Open On-Chip Debugger 0.4.0 built with -enable-ft2232_ftd2xx -enable-usbprog I'm looking for some help running openocd with Teensy++2.0 (Arduino) using a MacBook/snow leopard.
