General question to self made Arduino board

Hello,

i plan to integrate a arduino and a ft232 in a other circuit, before stating i like to clear some questions and check my understanding.

  • does a simple programmer http://www.arduino.cc/en/Hacking/ParallelProgrammer connected to the ISP is enough to burn the bootloader with uisp under linux?
  • why this http://www.amwaw.edu.pl/~adybkows/elka/ispprog.html programmer uses totally different pins of the ISP and the parallel port the the one above?
  • the ft232rl has an internal eprom, does i have to write any data to it for using it similar to the one on Arduino Diecimila?
  • i can't find a ft232rl in a 'normal' dual inline package, i afraid there is no ... ?

ok, so many questions, sorry :-[

Tanks, and kind regards

I use WinXP with parallel port programmer with uisp or avrdude. It works well. I think with linux is the same.

I think the pins used in parallel port (DB25) are different because the software is different, sending the information to different pins. And the circuit is different too. (BTW your link has a very interesting hardware and software)
The ISP pins are different just because of standard, but both has 6 pins (but parallel port programmer don't use +5v - it presumes you're using onboard power supply to IC).

I'm not sure, but I think you don't need to write to FT232RL eeprom. And forget about a PDIP (plastic dual inline package) version. There is only SMD versions SSOP-28 (for smd soldering) and QFN-32 (for smd socket). I think that's why all DIY kits has the FT232RL already soldered on the board.

thanks for the quick answer.

ok, and with uisp/avrdude you use this programmer http://www.arduino.cc/en/Hacking/ParallelProgrammer ?

The ISP pins are different just because of standard, but both has 6 pins

the ping numbering on the ISP connector described at Hacking/ParallelProgrammer matches to the Arduino Diecimila board?

(but parallel port programmer don't use +5v - it presumes you're using onboard power supply to IC).

no problem i handled the power supply on my board.

(BTW your link has a very interesting hardware and software)

I found the link here (see last post) http://www.arduino.cc/cgi-bin/yabb2/YaBB.pl?num=1142106610
Yes the hardware with the line driver 74244 looks more confident than the one with the resistors :wink:

Yes, there are many other parallel port programmer circuits, but the cheaper is that one with resistors. If you're planning to use it with Arduino, I think it's enough.

Hi,

after some month I'm at last back on my project from February :wink:

Because there is no DIL package version of the ft232 available does anybody know if there is a other USB/Seriell converter in a DIL package which I can use instead?

Nope, but there are devices like the SparkFun breakout board or the TTL232 cable that has the FTDI in it; these will provide some non-SMT access to the FTDI. You can also use a MAX232 type circuit and use a standard serial port, or a standard USB-rs232 adapter if you already have one.

Thanks, nice boards this fix my SMT solder problem :wink:
