Hi All, Most of us use desktop computers in conjunction with our ham radio activities. I converted to Linux Desktop from Windows back in 2007 moving from Windows XP => Ubuntu => Linux Mint => MX Linux

I've been playing with the ATtiny's ADC and POT to see how to tune 7.000MHz to 7.500MHz Attached is my first pass, no doubt lots of bugs, not optimized, debug tests Not removed, etc. But check it out.

Hi All, Reference http://kitsandparts.com/tutorials/ATtiny/105/ check out ATtiny.105.asm The current code links the tune potentiometer at J5, to the 5351 clock chip. see http://kitsandparts.com/tutori

Good afternoon, I am late to the party as far as programming goes. This morning I started my assembly language programming on my Raspberry Pi 4B system running the Rasberry Pi OS (Debian Linux). I hav

When I scoped my non-working board mounted Si5351a chip several days ago, I noticed some noise on the signals. To today, I scoped them again, with the Adafruit Board up and running and generating a si

Is anything actually gained by saving temp1 and temp2 when the interrupt is called? I acknowledge that is is an good example of push/pop to properly manage an ISR, but in this particular code, is it f

Diz, I enjoyed the teleconference today. And I'm greatly looking forward to looking through your ASM Code, and learning all your secrets. hi hi Everyone that wasn't there, you're missing out on golden

Diz, For those of us who do not have the right software to display *.sch or *.pcb files... Can you please add image files (.png?) to the Tutorials/ATmega328 folder and Tutorials/ATmega644A folder? ( L

Received yesterday. Good value, lots of parts for the price. Now on to the build and getting new version of AS working. Bob WA1EDJ

Diz, Did you get enough interest to produce a second run of kits? If not, then I will order a Si5351 breakout board and breadboard what I need to follow along. Thanks and 73, K1RBY --

I thought I'd give this a shot and pass along my experiences. I'm using Studio 7.0. I downloaded it last year while getting back to an old ATMega368 project I'd started in C long ago. And realizing th

I assembled the ATtiny.105.asm OK and sent it to the board. Installed a 7 position female header on the J6 position on the board and plugged in my Adafruit clone. I hooked up my scope and see I'm gett

Received my PCB Kit yesterday. I used solder paste and heat gun to install all the resistors and caps, except R4 and R 13. Diz, What is a "10 ohm fuse"? Is it just a regular resistor, or a special par

Hi Jim, et al... I've been using MX-Linux, AVRA, AVRDUDE and Gedit as my asm text editor for years...so you use Geany as an IDE? I'll have to try it...not sure what advantages there are for me but I'm

X1 Not Included! You supply. Is the Crystal for X1 the same frequency as X2? I.e. 25MHz ? Also, I'm assuming if ExtClock is used, then X2 should not be installed. Correct? Thanks, Mont

Finally got around to building the first of my HYCAS boards and am pretty excited about it but have a few questions. 1) For manual gain control, I put a 10 k voltage divider pot to ground on the AGC l

Hi Diz, The Clock Prescaler selected in "ATtiny.105.asm" is different than the previous ASM files. Was this intentional? Thanks, Mont

I got my box of parts in the mail yesterday. Even "at cost", it's an impressive collection of parts and components for $16 ppd. I got enough parts on the board to test the early programs and my abilit
