Again, I say, look at the Tiny26, which does come in a DIP. I am using it for very similar type control, using solenoid coils and linear-stepper-motor coils. Ken > I've looked at the higher pin count parts some but there are a couple of > problems with them. This will be just a h

Yes, the input has to be in radians. degrees * pi/180 = radians or degrees/57.295779... = radians The output would be a decimal number between -1 and +1. Zack On Mon, 13 Mar 2006, wbounce wrote: > In the Math routine documentation it said that sin function returns the > sin of th

Chuck, Did you strap some pins on the pc connector side? Look at the AVRISR schematic to see what they did. I think I got this right... From the PC ... On the 9pin connector that plugs to the PC, it is 4-6, 7-8, ( 5 gnd, 2 receive data by PC (transmit from Butterfly) and 3 transm

1287 analog signals and that many A/D channels that can run in complete parallelism? Maybe then, you need a lower sample rate or use delta coding. Sounds like a pipe dream to me. -----Original Message----- From: AVR-Chat@yahoogroups.com [mailto:AVR-Chat@yahoogroups.com] On Behalf

Is there any easy way to stop timer 1 in PWM mode, with the output pin high? I'm using OC1B to generate an output with 100% - 0% duty cycle. I realize that I could turn off PWM mode entirely, returning the pin to a straight I/O. I could make the turn-off conditional on getting a

In my quest for more RAM on an M128 ... Of course, sadly, I'm answering my own questions here, but nevertheless, a few SRAM chips I've looked at, including the Cypress CY7C109B have a guaranteed VOHmin of 2.4 Volts (at -4 mA) but the Atmel's VIHmin is 0.6Vcc, or 3.0 Volts, when r

I'd forgotten the lack of ADC on the 2313. Looking over the data sheet again I think that the TWI hardware on the 48, will work better in this situation than the USI( Universal Serial Interface ). I have to suggest the 48 also, even with the larger size ( 28 pin ). Martin Jay McK

As long as you aren't going to need more than 127 controlled by the same master I2C sounds just about perfect for the application. You specified: 2 - outputs 1 - input 1 - interrupt 1 - ADC Serial Communication ( 2 pins for I2C ) With the above requirements I'd say that the 2313

For a task like this, take a look at the Mega48. It is one of the newer, low-cost processors that still has a DIP version. It has more I/O pins so that an app like this might take less external hardware. Jim On Sun, 12 Mar 2006 14:43:28 -0700 "Timothy D. Lenz" wrote: > I have bee

I assume that when you say VB Express you mean the new one with .NET 2.0 ... If that is the case then what you want to do is super easy. I have some code laying around that is in C# that I used to send commands to my butterfly; receiving is just as easy. Just search the help file

I am adapting a Butterfly to a small control application as part of my efforts to become more 'fluent' in AVR applications. I'm progressing in the AVR code but I have a non-AVR need that I'm sure someone on this list has dealt with in the past and I'd rather not re-invent the whe

What in the world would drive the need for 5Mbps sustained from an AVR (what port at 5Mbps anyway) via 802.11? As you may know, '11b at the TCP layer is 6Mbps; 11g can be faster. The huge problem with 802.11 is that these radios are power hogs. The PDAs use 802.11 in the power sa
