PC2-5 are the JTAG port. You need to disable that feature in the fuse settings (programmer, fuse page) to enable those bits as normal i/o bits. Cheers! -----Original Message----- From: Dave VanHorn [mailto:dvanhorn@cedar.net] Sent: Sunday, January 11, 2004 8:44 AM To: AVR-Chat@ya

Does anyone know if AVRA accepts a directive to echo output to console? What I'm after is something that will let me log what options are turned on or off in a given build, like below in pseudo-code .equ Option_1 = True .equ Option_2 = False .if Option_1 .comment Option 1 enabled

My son is trying to use a Mega16 to drive LEDs on PortC using Bascom. Bits 0,1,6,7 work but 2,3,4,5 do not. The port is set up with Config Portc = output. The same code works on PortA but he does not want to use that port as it is the A/D converters. The LED code will eventually

I did a couple projects with 7-seg LEDs on another processor, but I think what I learned was relevant. I got eval units of the Max7219 and other LED driver chips. They are nice and self contained, but very expensive, >$10/each! Had I used those chips, it would have doubled the se

You can use MS DirectX SDK. There is a VB.Net sample (could be done in VB and possible eVB too) included in the SDK to use a joystick. I have played with the sample. Jeff _____ From: Stuart Whelan - Simulation Hardware LTD [mailto:stuart@simhardware.co.nz] Sent: Thursday, January

1. Don't print so often, or, make the ADC clock really slow, or don't use interrupts and just do conversions in your main() routine with a suitable delay between conversions & printing. 2. Enable the internal pull-up to make the unused ports to read 0x3FF, or make them outputs an

Connect the ADC to the junction of the Cap and the resistor. Then the audio signal will be summed with Vcc/2 and give you +/- 511 counts on your ADC results after subtracting 512. As long as your audio input doesn't exceed +/- VCC/2 you won't clip. -----Original Message----- From

Of course an external and dedicated chip is the best and easy option. By the way, generating DTMF is not as difficult as is decoding it, so it can be done by software. I did it many years ago using a bare 8051 and 3.57MHz clock, produced a mix of two several points sinewaves, mix

You can speed up the ADC by specifying a small clock divisor. The default is around 64 or 128, but you can specify 8x or even 4x and get much faster conversions. The accuracy will suffer, but, so what. With a 4mhz clock and a clk/4 ADC clock, each conversion will take 13 us for a
