4.3 Install the driver

The LPC1114 on the UMFT12XEV board is pre-loaded with firmware supporting Communication Device

Class (CDC class). The major OSs support the CDC protocol on their USB stack to use serial port

communication, allowing PC’s to access the CDC device through a virtual COM port (VCP) without

developing a new driver.

Linux recognize the CDC device as /dev/ttyACM# (# denotes a number). The driver is loaded

automatically when the device is connected.

Mac OS recognize the CDC device as /dev/cu.usbmodem# (# denotes a number). The driver is loaded

automatically when the device is connected.

Windows has a CDC protocol driver (usbser.sys) to generate VCP. However, it requires a “Setting

Information (INF)” file at the first connection. The required INF file can be download from FTDI website

http://www.ftdichip.com/Products/Modules/DevelopmentModules.htm.

Here is an example of driver installation under Windows 7 32-bit system:

 Connect the daughter card USB connector to the test PC with the micro-USB-B to Standard-A cable

 On Windows 7 PC, open control panel->device manager

5 Running demo tests

The UMFT12XEV is pre-loaded with a default firmware. The firmware can auto-detect the daughter card

type, and the LPC1114 MCU can communicate to the FT12 series with either SPI(for FT121) or parallel

(for FT120 or FT122) protocol. For bus-powered configuration (default setting), the FT12x evaluation kit

will power on when the USB cable is plugged in. LED D4 (red) on the main board will be ON, indicating

the 3.3V power is ready. The D2 and D3 LEDs (red) will be flashing, indicating the firmware is up and

running. For UMFT120DC and UMFT122DC, the LED D1 (green) on the daughter card will be tunred ON

upon successful enumeration, and blinking when there are USB transactions.

The default firmware supports USB CDC class driver. Upon enumeration a virtual COM port is present on

the PC. User can run serial port applications such as serial loopback test, teraterm, hyperterm etc.

5.1 Serial Loopback test

Follow the steps below to run the serial loopback test over the FT12x USB serial port interface.

- Install the serial loopback test utility. Download v1.10 of the serial loopback test utility at

http://www.madsencircuits.com/serial_loopback.html .

- Start the loopback test by clicking All Programs -> Serial Loopback Test -> Serial Loopback

Test.

- Select the Serial Port number from the pull-down list. In this example COM25 is selected.

- Click “Start Test” button. The utility will send data to the FT12x USB serial port, receive

back from the same serial port, and perform the comparisson of the received data from the

sent one. The FT12x Evaluation kit firmware will route all the received data back to the PC

internally (the firmware will store the data from bulk OUT endpoint, and send it back when

the bulk IN token comes).

Figure 5-1 Serial Loopback Test

5.2 USB Charger test

The FT121 and FT122 supports USB Charger (Wall Charger or Dedicated Charging Port) detection. The

USB Charger shall have micro-B plug with its D+/D- pins shorted.

FT12 Series Evaluation Kit Datasheet

Version 1.0

Document Reference No.: FT_000728 Clearance No.: FTDI# 314

Follow the steps below to check the USB Charger detection function:

- Connect the USB Charger to the micro-B USB connector of UMFT121DC or UMFT122DC

module.

- Plug the USB Charger to the Wall power socket and switch on the power.

- The yellow LED (D1 on the UMFT12XEV main board) will be turned ON. This indicates a

USB wall charger or dedicated charging port is connected.

7 Firmware Upgrade Process

The firmware for the on-board microcontroller LPC1114 can be upgraded through either UART (ISP mode)

or JTAG/SWD interface. This section will describe the steps on how to download the firmware through

ISP mode. For the usage of JTAG/SWD interface with LPC-Link debug module, please refer to NXP

LPCXpresso homepage at http://ics.nxp.com/lpcxpresso/. Note that the LPCXpresso is an integrated

development platform for firmware development, debug and download for NXP’s ARM-based LPC

microcontrollers. The LPCXpresso development tool chain can be downloaded from

http://lpcxpresso.code-red-tech.com/LPCXpresso/ .

Check the FTDI website for the available pre-compiled firmware for FT12x Evaluation Kit (

http://www.ftdichip.com/Firmware/Precompiled.htm ).

7.1 Put LPC1114 microcontroller in ISP mode

- Use a jumper wire to short pad 38 of J1 to pad 1 or pad 54 of J1. This is to connect the LPC1114

P0_1 pin to GND so that LPC1114 will enter ISP mode after power on or reset.

- Connect the board to the test PC via the micro-USB cable. The USB–A plug shall be inserted in

the PC USB port, while the micro-USB-B plug shall be connected to the daughter card USB port.

The board will be powered on with the LPC1114 entering ISP mode. Note for self power

configuration the daughter card is not required to be present for firmware upgrading. For bus

power configuration the daughter card is required as the power comes from the daughter card

USB port.

Figure 7-1 Plug in micro USB cable

7.2 Connect the TTL-232R-3V3 cable

- Connect the board to the test PC using a TTL-232R-3V3 cable. Plug the 6-pin socket of the cable

into the CN2 pin header. Please note the direction of the cable, the black wire (GND) should be

plugged in to pin 1 of CN2.

- Connect the other end of the TTL-232R-3V3 cable to a USB port of the test PC

7.3 Upgrade firmware

- Download and install the driver for the FTDI TTL-232R-3V3 cable. Refer to the cable datasheet for

details ( http://www.ftdichip.com/Support/Documents/DataSheets/Cables/DS_TTL-

232R_CABLES.pdf )

- Download the Flash Magic firmware programming utility from http://www.flashmagictool.com.

- Install the utility on test PC by running “FlashMagic.exe”

- Once installation is complete, launch the utility from Start -> All Programs -> Flash Magic ->

Flash Magic.

- Configure the tool by the following steps:

o Click “Select Device…”, choose LPC1114/302 from the popup window and click OK

o COM port: select the COM port number associated with the TTL-232R-3V3 cable. The

COM port number can be found in the “Device Manager -> Ports (COM & LPT) -> USB

Serial Port (COM3)”. Note on different PC this number can be changed.

o Interface: select “FTDI USB-Dongle” from the pull-down list.

o Oscillator (MHz): key in ‘12’.

o Tick the box “Erase blocks used by Hex File”.

o Select Hex File: browse to select the desired firmware binary hex file (ie “LPC1114-

FT12x.hex”).

o Tick the box “Verify after programming”

o The tool is configured ready for firmware downloading.

- Click “Start” button and the firmware download will begin. Typically the download takes about 2

minutes. Once completed, a ‘finished’ message will be displayed in the status bar (bottom side),

and the green download progress bar will reach 100%. Note the ‘finished’ message may

disappear after a while. If no message is displayed in the status bar after a few minutes, this also

indicates that the previous download is completed.

- Power off the board. Remove the ISP jumper wire and then power on the board again. The new

firmware will take effect.
