I've got a Bus Pirate, but haven't really worked out what real-world application I can use it for. The Logic analyzer is very useful, I use that practically every day.I just Googled for examples and found this:http://www.starlino.com/bus_pirate_i2c_tutorial.htmlI suppose what Bus Pirate does, that an analyzer doesn't, is let you feed data into the stream. Is that what you use it for?
As I broke my only RTC, I decided to buy another one. Plus 29 spares :http://www.ebay.co.uk/itm/30PCS-DS1307-2-Wire-Real-Time-Clock-DIP8-IC-/260816379486?pt=UK_BOI_Electrical_Components_Supplies_ET&hash=item3cb9de1e5e
Then I added a USB to TTL convertor for playing with:http://www.ebay.co.uk/itm/USB-2-0-TTL-UART-Module-SERIAL-CONVERTER-6pin-CP2102-/160641428244?pt=UK_Computing_CablesConnectors_RL&hash=item2566f9ab14
And why not an RS232 to TTL convertor, while I'm at it? :http://www.ebay.co.uk/itm/RS232-Serial-Port-TTL-Converter-Module-MAX232-/130400068620?pt=UK_Computing_Networking_SM&hash=item1e5c73240c
Oh yes, because my computer has no RS232 port. Add a convertor cable to that:http://www.amazon.co.uk/USB-RS232-Converter-Cable/dp/B00077DJIQ/ref=sr_1_1?ie=UTF8&qid=1314730092&sr=8-1
that was pretty cheap. I just ordered 50 spares at dipmicro.com
I have that too. Same chip CR2102. Not too bad. Just mine has no proper pin to reset arduino for upload.
Got MAX232 but never got the time to experiment on.
