I noticed a strange new microcontroller called PICAXE in one of the catalogues i got from Austronics 2005 last week. After some googling, i found out that PICAXE is actually a PIC with a bootstrap code from the manufacturer. Does anyone have ever used PICAXE before? Selling micro

Don, Thanks a lot for your input! It may have been karma or whatever, but after "knowing" it should work - it did. Actually, I did make a couple of changes. The power supply was marginal (you really need more than a 6V input for a 7805 regulator) and upgraded the software. Jeff E

well, we have done this before making all network layers containing TCP/IP at layer 4, on Mega128 now here is a Complete TCP/IP module for Data transfer or controlling everything even by gaining access to websites. may be we can help you with your project. M.Reza Keshtkaran

Recently I purchased several Tiny13's, but have been unable to program them via ISP (my only option at the moment). After reading through the manual, I'm guessing that the DWEN fuse is set. Will Atmel's programmer be able to re-program the fuse or do I need to purchase the new JT

Yes - sort of. You can step through code but it can get difficult stepping anything that has interrupts. If you are not doing interrupt stuff then you should be fine. Also be aware you can only set 3 breakpoints. -----Original Message----- From: AVR-Chat@yahoogroups.com [mailto:A

If you've got a decent sized filter capacitor (e.g. 10n) between the input pin and ground I imagine that would constitute a 'very' low impedance to charge anything inside the Mega88 even if the capacitor was fed from a series 100k. Dave Pallant AVR-Chat@yahoogroups.com wrote on 1

Yes, I always put in an external RC between any sensor and the A-D input. It's a bargain in space and cost, taking advantage of the high input impedance of the A-D (i.e.no opamp required). Ken > At 04:54 PM 9/11/05 -0700, Ken Holt wrote: >>I second Larry's suggestion for using II

Well, that was an interesting reply. 5V is NOT the high level for TTL. Never was. It's not the high level for CMOS either. 5V is the VCC level for TTL though. Each logic family determines it's low and high thresholds. TTL levels are well defined here: http://media.iet.hist.no/lab

I second Larry's suggestion for using IIR filtering. I use a sequence of them for my noisy accelerometer applications, (as well as other sense inputs), and gain flexible low-pass filtering and increased resolution. They are very easy to implement in AVR. Ken Larry Barello wrote:

A little more detail on sensor used, how it is read and the nature of the noise that is troublesome and what the application is would help in determining what, if any, filtering is needed. You can get only so much resolution using RC filter. In the case of the AVR the ADC is only

Apparently there is no simple way to connect two or more AVRs together using I2C protocol in BASCOM, since they are configured as masters internally. If you find a solution (Bascom), pls let me know. Don Kinzer kindly answered to this question of mine, yet I couldn't getuse of it
