I already have one of the modern device BUB programmers, and it works a charm. The small LED on the Arduino board, next to the digital pin 13 marked as ‘L’ blinks each second if you upload this program. The following figure shows the connection chain: Bluetooth HC07 module with Backplane 4 Pins. If you try to exceed mA, bad things can happen. RS uses a negative voltage for a logical 1 and a positive voltage for a logical 0.

DKU-5, ftdi, hack […].

It’s phone end has 6pins and the other end is the USB. If not, we move on to the next step where we strip the chip on the USB end.

Ex-Link Cable for C/D/E Series and BD players

To do this cut the cable a couple of inches 5 cm from the phone connector. Some people end up with 3 wire cables while others get 4 or 5 wire ones.

Finally will looks like: Here is the finished FTDI cable: However, I can almost guarantee your colors will be different so you must perform the steps described above. This means the maximum current your circuits should draw is mA minus the current required by your cables circuitry.

I did not unsolder them for fear of breaking some unknown connection, rather I simply clipped them at their pads. This post was a life saver, and really saved me a LOT of money! Be aware that most setups put the reset capacitor on the board, so if you use your cable with one of these boards your total capacitance will be effectively halfed and it will hold the reset pin low half as long.

srial Your computer may beep, reset or even smoke. I read the thread and it appears you discovered the problem was caused by a USB extension cable.

DIY USB to Serial Cable For $3! | Jonathan Thomson’s web journal

And there another cable that was useless. You will find a PCB with the chip on it. Update Several good, inexpensive, purpose-built USB to serial modules are now available on sdrial for around five to six dollars.

It will look like this once done: Jonathan, I ordered my Nokia cable from HongKong and followed your writeup.

It is especially suitable for multimedia devices sedial use a lot of battery power when downloading large data files. RX, TX and 3. A resettable fuse is highly recommended. If you want to do serial communication with the ATmega you need sserial put code on it to do so.


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. Thus its a definite advantage to buy a pre-fabricated USB-to-serial converter using 3.

Bluetooth HC06 module with Backplane 6 Pins. Please note that the section showing the bottom of the board was vertically flipped in GIMP to give a sort of X-ray vision effect.

The 1k resistor on the Rx pin is for limiting the current through the input protection diode if the Tx line exceeds 5V. Studying a picture on your computer beats the hell derial of using the magnifer on a Helping Hands. If they are displayed, then you have correctly identified the TxD and RxD line. Diy serial Cable with cheap phone cables Says:.
