How do you high voltage serial program an 8 pin SMD Tiny?
An alternative way to make a surface-mound SOIC microcontroller programmer is to have a small piece of copper-clad board and cut out a precise outline for the body of the SOIC to...

Tiny11 expert help?
Here's an assembler file for this application. It took about a half hour to do. It's always more complex than it seems at first. This is the kind of ap that that Tiny11 is...

need keypad 3x4 source?
Hello, Are you asking us to do a homework assignment for computer class? Anyway, a 'keyboard matrix' algorythm is not complex. Each output port line will have four push...

"Wolf Whistle" algorithm?
To make a simple tone from an AVR output, connect the output to a small speaker through a resistor say 200 ohms (5v/200ohms --20mA; actually less current due to the speaker's AC...

ICE200 difficulties and questions
Well, the "no monitor" message seemed to come from not having grounded the capacitors that are connected to the 4MHz crystal that is used for the system clock. The target system...

budget oscilliscope
To view and store signals 20KHz or less there are several good PC programs that use the sound card digitizing line inputs. Try a Google search. These scope programs also require...

AVR vs PIC (mouhahahahaha)
People use PICs for two main reasons . I have been studying the PIC architecture recently and have been using AVRs for five years. Often because they have code already written...

8 seg LED & 2313 problems
I could be the current limit on the transistor itself. They are rated at 100mA. Also the Absolute Maximum (page 65 of 71 of the 2313 PDF data sheet) Value for the VCC pin is 140...

Tiny26 ISP Programming Problem
Try (if possible) using a slower programming frequency. Try 4MHz instead of 8MHz. The last 1990's series of 2313s had the maximum programming frequency be 4MHz. Maybe these...

AVR Microcontrollers
I believe that the main two advantage of AVRs over PICs are the expanded instruction set of AVR and the one instruction per system clock cycle speed of the AVR. Secondary...

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