The nRF ICs require you to write your own protocol. They are really handy, and extremely flexible units (not to mention really cheap), but they require the end user to do a lot of firmware and protocol stuff to get them going. It's the same $ vs. time problem. Bluetooth is very easy, but a bit more ...

My $0.02 - the mfgs who write the datasheets are just covering their asses for production runs. You can do some really evil things to ICs (over heat, super cool, run too fast, etc) without too much problems. I've over clocked PICs to twice their spcd speed without damage. I've run 5V parts at 3.3V w...

We use a recommended CFAX part from the CrystalFontz forum : the HV826MG available from Mouser. SSOP 8 is a bit of evil, but SOIC 8 is also available I believe.

Tom Igoe is a dear friend of SFE and an avid Arduino developer. The shields principal is just starting to get traction. There was talk at Sketching 06 (www.sketching06.com) that there were all sorts of shields being worked on. So far, we've only touched 1-2pcs protos. We are happy carry anything ava...

Hey Cannibal, Walk your line carefully. The minute you start picking on people for their creative use of the english language or their politics (which you seem to have intuited all on your own), be prepared for little or no help. Plainly, Tsvetan has been as kind and as helpful as time has permitted...

Replies: 6
Views: 2759

Yea - we don't sell the PICs preloaded any more. It was too much of a hassle keeping inventory seperate. One was always out of stock and we had to switch PICs back and forth. All you need is a PG2 to get a DIP programmed with the bootloader. Once the bootloader is in place, you shouldn't need to pro...

Hi,

Don't tile the boards, just submit them seperately. You can still order them all at the same time, under one handling fee.

Save yourself the hassle,

I just hooked up the ADuC 7020 the other day. Using Rowley Crossworks and the Analog boot loader, it works like a charm. That was the fastest I've ever gotten a LED to blink on a new platform!

:) It was the same quarter for many months. Then I think our Roomba ate it.

Most recently it looks like I forgot to flip it Washington side up.

Hah! Thanks for asking ;)

Hi Aaron,

We've posted example test code using a PIC... Should be a good place to start.

Hi, I've noticed shut-downs with the GM862 when there are problems with power. So I will gamble that if you have no SIM card in your GM862, it will stay on indefinitely while it searches for a network (but you have no SIM so it will always be in search mode). If you insert a SIM, the unit will be on...
