Could you please share your sketch? Thanks!
hi .. did you find out how to change the crystal on these ad9833 modules? was the pitch more accurate? thanks
Why do you have norwegian coins there?? D:
not completely sure of the details on how the oscillators work on these, but could you desolder all but one from the eventual four tone generators and just link the clock pins of IC together?
Link to previous video about this project?
can you re-address the I2C in tone modules and work it into software, enable lines can be glitchy without delays(5);
Love it, you should know better Julian. Back in the day when I was at uni I was taught structured programming in Pascal, (a long, long time ago), functions were the key to everything, along with linked lists that is. Funny thing, we started that semester course with 60 students, by the time we finished and moved on to COBOL there were only 5 of us left. I've been searching for examples of linked list use in Arduino programming, not too many about and, as it happens, I don't think most people make the best use of functions either.
Takes me right back, local variable, global variable, parameter passing, scanning and sorting algorithms for linked list and, the pinnacle, recursive functions!
Penny Organ… I once knew a girl called Penny Organ…
gud
your going to end up going to a arduino mega eventually to accomodate all the outputs and inputs…
Awesome video! btw where can i buy modules like that?
Looks like youtube misinterprets what kind of an organ gets oscillators here. The suggestion on the right are way off topic 🙂
At the end are the tones phasing, or could it be beats, caused by two similar frequencies?
If you want to be sure you don't write to both modules at the same time you could use something like a 74138 and then your output pins can write in binary like an address bus. that way you can have 8 modules from 3 pins.
Awesome my friend.
Is that the one arduino with the broken oscillator that you've fixed?
