Good Programmer and Chip
I use the SP12 'Spider's Brain' AVR programmer found at: http://www.xs4all.nl/~sbolt/. This works well even if it is DOS and the command line is difficult to understand. The...

AtMega8, reload the Timer0 automatically ?
The value that you should use to reload the timer/counter register should be the period of the interval divided by the system clock. If the amount is greater than 255 (or 65535...

choosing an oscilloscope/logic analyzer
At the risk of losing any and all electronics credibility, I might suggest using one of the various sound card oscilloscope programs that are downloadable from the web. All...

From 8052 to AVR
Hello, I've done assembly language programming on small projects for both processers. I find the AVR easier to work with in most instances. The one instruction per clock...

AT90S2313 to Tiny26 communication
As a brief answer, the fastest way to exchange data between a 2313 and a Tiny26 is to connect the 8bit ports together. This is assuming that you have ten pins free on each chip...

This isn't another PIC vs AVR flame war....
I am considering (vaguely) using a PIC for a small run (about 20) of a PC_keyboard_to_MIDI_Notes project (#186 in the project forum here). I'm looking for an 8-pin device that...

2313 UBRR doesn't work correctly at high speeds
This problem turned out to be an initialization issue. Using SBR to change bits in a temp register left a bit set from a previous instruction. This caused the UART to be in 9...

ATtiny13 Timer interrupt problem
There is a missing operand for initializing the timer interrupt flag. I suspect this is just a typo. Does the interrupt work just one time? In that case try resetting the...

avr programmer
I've used the SP12 (with Ken's dongle - a signal buffer) located at "Programming a Spider's Brain" (do a Google search). It has worked quite well after reading the dense...

code works with ICE200, but not when removed
I use Studio 3.56 or 3.52. I had difficulty getting version 4 to work. I don't know if it was the program, the interface, or just me. But I can get work done with version 3 and...

code works with ICE200, but not when removed
I'm going to check the reset line. My wire-wrap socket that connects the fragile ICE200 20-pin DIP connector to the circuit-under-test has a 10K resistor connection from VCC to...

STK500 or BASIC Stamp?
I think the question of STK500 vs. BASIC stamp is a question of AVR vs. PIC microcontrollers. This can get somewhat heated here. My two cents worth on the subject is that there...
