Can anyone point me to a source (or sources) that stock Atmega chips? I need 25 - 50 atmega8515-16 in 40 pin DIP, either standard or industrial temp rating. My usual sources (digikey, mouser, newark, etc.) don't have any and no word when they will be coming in. I've tried findchi

I’m pretty familiar with uC/OS-II (a Real-Time Operating System at www.micrium.com) for use with a lot of different microprocessors and microcontrollers. This is my first application with the ATmega64. The internal 4K RAM will just barely handle the requirements… I think. Who els

It sounds to me as if your chip is running at the default 1MHz. You will need to make sure your clock fuse bits are set for 8MHz and match the compiler project configuration in Codevision. The fuse bits for 8 MHz are CKSEL=0100 i.e. CKSEL3 = 0 (checked) CKSEL2 = 1 (unchecked) CKS

I used the following code for GCC on a 16-MHz Mega-8. It seems to work fine for me. I also used the same code on an 8-MHz Mega-16, but setting TCNT0 to 131 (125000 counts/sec and 256 - 125 = 131) gTickCount gets incremented once every millisecond. volatile uns16 gTickCount = 0; /

Oh, I remember reading something about that awhile back. Someone suggested a fuse, and with the double-diode you mention, that should make it fairly safe. For those that are not electronic technicians, there are no electronic circuits that beyond failure. By all means a mechanica

I think this should quite doable within a $12 BOM budget if not significantly below that. If a standard LED is bright enough, you can drive the LED directly (assuming a 20 mA drain - less with flickering) so no need for a drive transistor. Internal oscillator so no xtal/caps. I t

Sometimes hardware peripherals (is SRAM considered a peripheral? :) get into funny states that are not reset with a warm boot. Hence a power cycle is needed. I think the only reason it seems more prevalent with WinXP is that the OS doesn't crash due to S/W nearly as much as it's
