DIY USB to Serial Cable For 3 CHobby Jonathan Thomson submitted this useful article about converting a low cost cell phone USB cable into and easy and cheap way to connect to an Arduino microcontroller setup. Jonathan found a cable for less then 3 which can be hacked to perform the same function as the typical 2. FTDI USB cable often used in Arduino projects. Jonathan submitted as part of the u. What is the XDS100 The XDS100 emulator is Texas Instruments ultralowcost USBinterface JTAG hardware reference design. The XDS100 emulator provides JTAG access to. CHobby Giveaway project and has selected to receive a Plug in Bread Board Power Supply Kit for this article. Introduction. The Arduino board is a great way for beginners to start learning about developing software for microcontrollers however its cost, while a steal when compared to the initial investment required in the past, can be a little too steep for a do it yourselfer who wants to do things cheaply. To be fair there are Arduino clones that do lower the price a good bit, but the real cheapskates that dont mind doing a little extra work cant help but think they could do it for less. For these penny pinching DIYers setting up an ATmega on a breadboard seems like the way to go until they discover the FTDI USB cable is 2. What a heart breaker There are slightly cheaper alternatives, but a real scrooge Googles on. Well look no further because this article has just what youve been looking for. The trick is to use a Nokia cell phone data cable based on Prolifics PL 2. These cables have a USB to Serial TTL converter built right in. H.jpg' alt='Get Serial Number Computer Php' title='Get Serial Number Computer Php' />Theyre available on e. Bay and Deal Extreme and very inexpensive. I got mine for just 2. Data cables DKU 5 or CA 4. This article will focus on the CA 4. PL2. 30. 3HX rev. A. The methods described here should work in general for cables using different chips. Preparation. Tools. Wire Stripper Multimeter Anti static wrist strap Driver. Recent versions of Linux have the driver pre installed. Users of other operating systems may find drivers here. Install the driver. So you dont waste time with a dud cable or bad drivers, you should first check that its recognized and assigned a COM port In Linux, use the command ls devtty. USB before and after you plug in the cable. You should notice a new tty. USB is added after you connect the cable. In Windows, plug in the cable then open up the Device Manager by clicking Start Run and typing devmgmt. Enter. Now find the section named Ports COM LPT and click it to expand. There should be a port named something like Prolific USB to Serial Comm Port COM or perhaps NOKIA COM. Terragen 2 Deep Edition. Unplug the cable the cables entry in Device Manager should disappear. Precautions. Never work on a live circuit Always power off the breadboard and always unplug the cable before making adjustments to either Ive tried to remind you of this throughout the article but I may have missed a couple of places. There is a possibility you could damage your computer, some other property, injure or even kill yourself Ive tried to be very thorough in my instructions, this however is not an excuse for you to turn off your brain. In no way does this paragraph convey all of the various precautions one should take when working with electricity and electronics. Please read the entire article before you begin to modify the cable. Wear an anti static wrist strap. Probing. There are most likely several different manufacturers of these cables because the same model will have a different number and color of wires depending on who you buy it from. Therefore we will have to probe the pins of the phone connector to determine which wires are Tx. D, Rx. D, and GND. To do this cut the cable a couple of inches 5 cm from the phone connector. NOTE I said the phone connector not the USB connector. Most of the cable should remain attached to the USB connector, but you need to leave enough cable attached to the phone connector to be able to strip the wires and attach an alligator clip or a terminal block if you like. Strip each wire. Set your multimeter to diode continuity, and attach the black probe to a stripped wire. Now probe each of the phone connectors pins with the red probe until your meter beeps. Write down the color of the wire and its corresponding pin number from the picture below. Repeat until youve matched each color with a pin number. Not all pins will have a connection. You should double check your work because the wires are very thin and the pins are small and close together. Crackling Noise While Breathing'>Crackling Noise While Breathing. Pin 6 is the cables Tx. D line, pin 7 is Rx. D line, and pin 8 is ground. For my cable pin 6 was white, pin 7 was blue, and pin 8 was black. I also had two additional wires, one green pin 3, one red pin 4. However, I can almost guarantee your colors will be different so you must perform the steps described above. To be positive weve identified the wires correctly we can perform a couple of tests. Testing. Were now finished with the phone connector, so now well turn our attention to the remaining cable which has the USB connector. Strip the wires which correspond to pins 6, 7 and 8. Set your multimeter to measure voltage. Attach the black cable to the wire which corresponds pin 8 GND. Attach the red cable to the pin 6 wire Tx. D. Make sure none of the wires are touching one another Plug in the USB connector. The multimeter should read 3. V I measured 3. 5. V. Unplug the USB cable. Repeat the previous steps for the pin 7 wire Rx. D. The Rx. D lines voltage should be less than the Tx. D line. The other wires are not needed for communicating with your ATmega nonetheless the pin 3 wire measured 0. V and the pin 4 wire measured 3. V. Your cable may not have a pin 3 or pin 4 wire. For our second test well temporarily turn our cable into a loopback cable and use a serial communication program to see if weve identified the wires correctly. Make sure the cable is unpluggedTwist the Rx. D and Tx. D lines together. Make sure none of the other wires are touching one another Plug the cable in. A Gaiola Das Loucas 1978. In Debian. You must determine which device name Linux gives to the cable. For me, since I didnt have any other USB devices plugged in, Linux gave it devtty. USB0. If you do ls devtty. USB before and after you plug in the cable you should be able to determine which device name the cable gets by comparing the outputs. I used screen as my serial communications program. USB0 Press several keys on the keyboard. If they are displayed, then you have correctly identified the Tx. D and Rx. D line. If they are not displayed, youve done something wrong, reread and retrace your steps. To exit screen type Ctrl A. In Windows XPThe Preparation section explains how to find your cables entry in the Ports COM LPT of Device Manager. Repeat those steps and make a note of the cables COM. Then launch Hyper. Terminal Start All Programs Accessories Communications Hyper. Terminal. If youve never used Hyper. Terminal answer its questions about your location. When the Connection Description dialog comes up give it any name you like e. In the Connect To dialog change the Connect using   drop down to COM where COM is the COM number you made note of above. Click OK. In Port Settings change Bits per second to 1. Data bits to 8 Parity to None Stop bits to 1 Flow control to None Click OK. Press several keys on the keyboard. If they are displayed, then you have correctly identified the Tx. D and Rx. D line. If they are not displayed, youve done something wrong, reread and retrace your steps. Using with the Arduino.
