i2s mic & USB mic cpu usage compare

Hi, I did some searchs on the forum looking for any possible cpu overhead comparison between capturing audio with a i2s microphone and capturing audio with a USB audio adapter with microphone… lots of messages with i2s but could not find any directly related to cpu/resources usage… Does anybody have...

Re: Raspberry Pi PIC Programmer using GPIO

Hi, Recently, I was surfin' the interweb and came across you webpage about using the pi as a pic programmer. It just so happens though that I have a load of pic microcontrollers that I have no means of programming. They are called Pic16c84. Would it be possible to program them using this method at ...

Re: Add small cpu for R/C servo controlled

Hi everybody, just want to report the first beta release of PC version of the burnLVP programmer, the “pcBurnLVP” which runs on a regular PC and uses a USB programmer (picture)… https://dl.dropboxusercontent.com/u/29669031/psclub/mpb/simple_micro_PIC_burner_LVP_progPins_bb.jpg To help beginners we d...

Hi zeevy, don't know this is correct or not but this worked for me (read and write) #define PIC16F688 0x1180 const struct picmicro pic16f688 = {PIC16F688, "pic16f688", 0x400, 256, 2500, 6000, 8000, 8000, 0x00, 0x02, 0x03, 0x04, 0x05, 0x06, 0xFF, 0x08, 0x09, 0x0B, 0x0A, 0x1F}; const struct picmicro *...

Re: Snap! - can we get it to run on the RPi

If you pop over to the scratch forum thread I mentioned above you'll see that I managed to fix the problem with BYOB so you can now try it out on your pi. It seems to me that you are wanting pretty much what Enchanting, S4A and the Open University TU100 course people have been making. We really sho...

Re: Snap! - can we get it to run on the RPi

Let me ask you one question: What do you think is the "common ground" here, what is the option that will be "most compatible" (cross-platformness so to speak) amongst the current "visual block options"? My goal is to have a good (as platform independent as possible) option for this "visual block" t...

Re: Snap! - can we get it to run on the RPi

I'm looking into what might be causing problems with starting up BYOB3.1.1(etc) on the Pi. This is a slightly older version of !Snap built from Scratch. As-is it will not benefit from most of the Scratch performance improvements I've been developing, but once the basic system is usable it may be pr...

Re: Snap! - can we get it to run on the RPi

Hi Simon, Snap! is a block programming language heavily influenced by Scratch 1.4 but re-written as an HTML 5 web app. http://byob.berkeley.edu/ Since it runs entirely within an HTML 5 compliant browser - you can download the whole lot, stick ii into a folder and then use Midori to open up snap.html...

Re: Add small cpu for R/C servo controlled

Hi Jim, I am wondering how difficult it would be to apply your bit-banging method to some of the newer 18F chips like the 18F25K50 and 18F27J53 chips that can communicate via USB. These chips use the same 'magic' 32-bit sequence to enter ICSP LVP programming mode as the K80 series. To do this, would...
