Huh... so visual basic is already a ".net" program? Or is that just a function of what I want to do with it (serial/graphics)? Does/can the package deployment wizard include all those files in your install setup? I'd like to stick with what I know, and VB has a huge leg up over a

I'm very familiar with visual basic 6.0. I need to create an application that will allow me to manipulate a simple line graph, and to get specified points off it (to feed to an AVR... i.e. for like a LED brightness slope... if you see 1V (x) in A-D input here, put (y) PWM to the

More likely your problem is a too small variable stack or hardware stack or frame size. These are adjustable in Bascom under Options->Compiler->Chip. Bascom has buffers for the hardware serial ports that one enables with CONFIG SERIALIN/SERIALOUT compiler directives.. -----------

Hi I have to sell a STK500 kit which I bought 3 months back for my final year project. Anyhow now I am working and have these and other stuff at my office, so I plan to sell it off. It has following items included: STK500 Board AT90S8515-8PC sample microcontroller Atmel CD with D

Please do big code by posting a link, or uploading a file. Disable Interrupts ' to test if occasional errors in Log10 calc. comes from interrupts? Lux = Log10(r0) This part scares me to death. Interrupts are your friend. Honest. If something isn't done right in the ISR though, it

Well, it took time to put into practice your suggestions and advice. Now the breadboard is a new one, wiring is improved, and more important, the reason that seemed to be the cause of the problem, which is programming CKOPT, is done. The result: The same malfunction and unstabili

Using a car battery to power your AVR is like using an atomic bomb to heat your house! Make sure that you have a fuse to protect against over-currents and short circuits. With the instantaneous power available from a car battery, it will take only a few milliseconds to generate e

When it comes to dimming leds I would doubt very much that you are at your limit with software. Driving/multiplexing/dimming leds is a very non-critical non-time sensitive low overhead (all that sort of stuff) operation. What I can't figure out is why you have run your leds in th
