Identify an IC?
2008-01-01 by Tom Becker
Folks, I thought I had the tool to identify this part but, alas, I cannot find it nor relocate the tool online. This component is in a Logitech V400 optical mouse along with a ATMega168V, Philips PLN-2020 (the real object of the chase) and an nRF24L01. Can anyone help determine w

Hi Roy, Yes I went into the registry and deleted everything called Atmel, AvrStudio, & Avr Studio but to no avail, there must be something I missed but cannot think of what it could be, even deleted a couple of entries that I found out later pointed the C compilers to Avr Studio

If you've installed ver 4.xx, you might have to go into your registry files and delete everything to do with the older version. Some files are called in very unusual places all over the registry. That's a real pain in the tush, and other vital parts of one's anatomy. You might be

Nobody uses a frequency counter any more. Why not set a multifunction counter up for a start/stop period measurement...then if you can talk to it over any interface bus, let that puppy, the microcontroller circuit, run and log the time periods to run the routine. After a while, t

Optimisation is one of my favourite jobs. I enjoy finding faster algorithms and optimising code. On the PC I call subroutines many thousands of times and get the PC to report the result in time taken. On microcontrollers I tend to use a scope and pulse an IO pin at the start of t

Hi. I good approach for it is to calculate the MCU cycles. Doesn't matter if it is on C, to compile it, your compiler will create a file with your program in assembly. In the book Excel by Example, it teaches you how to create a sheat to calculate the MCU cycles based on assembly

One small startup where I worked, the founder wouldn't hire radio amateurs because he thought they'd tinker and play with a problem for fun instead of just solving the problem adequately for the needs of the project and then moving on. Sort of the flip side of enjoying your work.

Also, while we could provide some simple samples, the thing about the world of micro-controllers is that most applications (even simple ones) tend to be specific to the circuit used. i.e. I could provide you an example to blink the LED on an ATmega8535, but that program would onl

I got an STK500 and it was a great way for me to develop code while my "real" hardware was being manufactured and I also use it as a programmer for that hardware. I've also gotten good use from the BD Micro Mavric board. It brings all I/O out to either headers or screw terminals.

If you can get your hands on an STK500, you have a powerful learning tool for beginners. You can program simple tasks like reading pushbuttons and lighting LED's and then get them to work right on the board. I'd recommend this for someone who doesn't have much experience with mic
