Thank you everyone for your responses. As it happens I have a 10mhz crystal across 4 and 5 on the PCB already, with attendant 18pf caps to GND. I'm going to remove the crystal and try the AVRDUDE command line fix, that looks like the best at this point. If that doesn't work, I'll

Hi You can solder 1 - 4MHz crystal to pins 4 and 5 and try to set the fuses back again. then remove the crystal. good luck Ori --- weston54 wrote: > I have a Tiny2313 in an SOIC package soldered to a > PCB I made, along > with a 6 pin programming connector for my ISP MKII. > Ever

I had to comment. That is a totally cool question and yeah, it made me wonder. I don't know, I've never done this but yeah, if there is no other route to solution then I would somehow inject a signal at the xtal intput. Hopefully, you can just inject the signal via a probe. You m

As far as I know, IBIS is for a system-level simulation: http://download.micron.com/pdf/technotes/TN0007.pdf It is SPICE-like but includes circuits with very complex logic devices such as micros, CPLD, etc. You can describe the internal functionality of a device (the "code" it ru

ZigBee - I am guilty of assuming that Maxstream moved out of beta with Zigbee since it's "certified" now. I see they haven't. They have a huge number of beta testers. So a request may well be accepted. --- In AVR-Chat@yahoogroups.com, dlc@... wrote: > > According to Maxtream thei

re below... ZigBee 1.0 is a mesh by my definition: Nodes are configured with a network name. At power-up, every node seeks out its neighbors. A message from node A to node X may be relayed by zero or more nodes, mesh-like. ZigBee defines a "coordinator" node. This node manages ne

not sure why, at $19 for a module w/Zigbee you'd want to, you can roll your own meshed network. You can start with the public domain code from UCSB as I recall - part of the TinyOS work based on YEAH! AVRs. Some vendors (I won't name names) that are not in the ZigBee camp are ada

be sure to keep ZigBee separate from IEEE 802.15.4 which is the MAC/PHY spec to which the chips/modules are built. ZigBee is, so far, downloadable firmware as an option for the network layer. Some end-item manufacturers are using the '15.4 chips but their own network layer. ZigBe

Well, according to the Zigbee Alliance, 4 vendors have qualified at the Gold level for interoperability and complete Zigbee implementation. TI/Chip conis one. You'll have to consult with Zigbee Alliance as to who the other three are. The Zigbee Alliance has an email newsletter/an

There is nothing stopping you from implementing your own "mesh" network - but it will be a ton of work... One of the Atmel Zigbee partners (in Russia) claims full mesh networking. They base their module off of a m128 + radio chip. The numbers are *very* good (makes the Xbee look

The project I worked on doesn't say "Zigbee" in the documentation. We say "802.15.4" radio protocol. I just use the mac addressing in a star configuration with the end nodes sleeping most of the time. Mesh networking sound sexy but apparently isn't quite ready for prime time... U

Now I'm confused. The manual specifically addresses sleep mode and indirect messaging in a non-beacon network. Is that then a custom XBee protocol that isn't Zigbee? In my conversations with Maxstream they don't even have mesh networking, only star networking since their Zigbee d

There are many antenna designs which "flatten" the pattern in the vertical direction in order to give more gain in the horizontal plane. They still have 360 degree coverage in the horizontal plane. The more you concentrate on this, the bigger they get, though. Zack On Thu, 8 Feb

I had a chat with MaxStream about the XBee modules (they were very helpful). To clarify the question of sleep mode: Me: I was looking at the XBee/Pro manual and it seems the Zigbee modules don't support sleep mode? MS: That is correct. The XBee's do not yet support a sleep mode w

You can purchase antennas that are omnidirectional on the horizontal but directional on the vertical. They have a pattern like a doughnut. The flatter the doughnut, the higher the gain. I have some that are 12dBi gain with 7 degree vertical beamwidth, but are omnidirectional on t

Remember, use of the ZigBee network layer is optional in all these 802.15.4 modules. Without ZigBee it's like using Ethernet without IP - you can address packets by the MAC address. The current (about to change) ZigBee standard says that end-nodes (network leaf) can sleep. Router
