Title: Ftdi sub lead
Post by: ploom2 on September 03, 2016, 12:08:10 AM
Hi
I've got the ftdi sub lead to upload firmware for atmegatron
I'm also looking to update micro granny firmware which seems to need this

https://www.sparkfun.com/products/9716

Are they basically the same thing or do you think I also need to get this red thing too ?
It seems to also connect to 6 pins
Cheers

Yup they're identical.  The black end of the FTDI cable aligns with the GND pin and the green aligns with the RTS pin (called DTR on the Sparkfun board).  Not sure what type of port the micro-granny has, so you may need to make a bodge lead, but as long as you do a pin to pin connection from the FTDI cable to the micro granny, it'll work.

another one of these questions.

is it basically the same lead used on the meeblip triode ?
looks similar ish except it seem to be 3x2 pins wise.

Hmm, no I don't think these methods are related, although they both use AVRdude to transfer the data.
The Anode seems to use an ATtiny chip which is programmed to communicate with the AVR chip in the Anode.  I don't think it uses the Arduino bootloader.
The Atmegatron uses an FTDI cable to communicate with the Arduino bootloader directly on the Atmega chip.
Similar but slightly different methods to achieve the same result.  Sadly no compatible kit though.
