"Hi Rich,
Great upgrades all around! Thanks a million.
Dan
ps. if anyone knows a better solution than Ning, we might consider migrating this website to something more 'user friendly'..."

New CUI32 StickOS v1.92 bits...
I just put new StickOS v1.92 bits up for the CUI32 (as well as other PIC32’s and MCF5225x’s) on the http://www.cpustick.com/downloads.htm website. The changes include: * fix usb host mode – now you can log to a usb flash drive trivially using “print” statements* add "lcd" statement to interface with HD44780-compatible LCD* add "analog" variable to return analog supply millivolts* add "keychar" variable and "keychars" mode to…See More

"And I just posted the skeleton project here: http://www.cpustick.com/downloads.htm
So if anyone wants, they can now rebuild a v1.82 StickOS for the PIC32.

Rich Testardi replied to Calegatter's discussion Hello World on LCD using StickOS
"I know this is an old thread, but I just added LCD support to StickOS in v1.82. It will be just a bit for that to be on the website, but it is coming. In the mean-time, here is the BASIC program I used to manipulate my LCD -- this was…"
Rich Testardi replied to Antonio Benci's discussion Sample and conversion rate for Analog inputs.
"Or you can use a timer and insert all the samples into an array, like the following that records 10 seconds of samples at 10ms intervals, and then prints them:
> list 10 dim i, voltages[1000] as short, string$[10] 20 dim…"
Rich Testardi replied to Antonio Benci's discussion Sample and conversion rate for Analog inputs.
"So... If you really want predictable samples, what I'd do is:
20 while 1 do
25 let voltage = potentiometer
27 sleep 250 us
30 endwhile
That will sample the a/d and then wait for the next tick to…"
Rich Testardi replied to Antonio Benci's discussion Sample and conversion rate for Analog inputs.
"On PIC32, the a/d's are sampled 4 times per millisecond -- that is our "clock tick".
So the code there will run really fast -- if you see below we ran the loop about 24 times per millisecond (with an extra statement…"
Rich Testardi replied to AWP's discussion CUI32 StickOS host
"You can't switch StickOS in and out of host mode with the switch (which just controls the power circuit, not the software) -- see: http://www.cpustick.com/stickos.htm#_Toc270602265
Switching back and forth is quite hard, but not…"
Rich Testardi replied to AWP's discussion CUI32 StickOS host
"How do you have the circuit set up? You need to provide 5V to the USB power pin -- you can do it many ways, but power has to be there before you plug in the memory stick.
You need to use "usbhost on" in StickOS to enable "host…"
Rich Testardi replied to Frank Verreijt's discussion Dawn Simulator using StickOS and CUI32
"And actually, depending on the program, "watchsmart off" can actually be faster... It is best to try both ways."
Rich Testardi replied to Antonio Benci's discussion Embedding CUI32 board.
"If you want to recompile for the PIC32MX4F512H without the hid bootloader, you need to:
1. download the skeleton project
2. remove procdefs.ld if it exists
3. edit config.h and comment out the HIDBL #define
4. In MPLAB 8.53, Configure ->…"
Rich Testardi replied to Frank Verreijt's discussion Dawn Simulator using StickOS and CUI32
"Hi,
1. I think the timer should not get behind unless you take significant time in your "on timer" routine... The way StickOS counts ticks, so long as you take less than the timer duration, I think we should stay on…"
Rich Testardi replied to Hans Hof's discussion No I2C signal from CUI32 board?
"What does your code look like? There should be no needed initialization. I assume you're running v1.80.
I2C should be on RD9 and RD10 on the CUI32 -- see: http://www.cpustick.com/downloads/microchip.pdf
"
Rich Testardi replied to Antonio Benci's discussion Embedding CUI32 board.
"Recompiling StickOS from the skeleton project is not especially hard... But I'm not sure what you mean by "to embedded firmware". Are you trying to get by without the HID bootloader? Or are you trying to get a BASIC…"
Rich Testardi commented on Jean-Francois Gauthier's blog post Need a quick way to start with the cui32 V18
"BTW, there is now a StickOS port for the MX795 at: http://www.cpustick.com/downloads.htm"
Rich Testardi replied to Calegatter's discussion Hello World on LCD using StickOS
"Way cool!
I think line 690 got munged with the html -- there should be a "<<" there:
690 let wb = wb << 4"

CUI32 is here!
Well, I just did a search for CUI32 on SparkFun, and it is here!
http://www.sparkfun.com/commerce/product_info.php?products_id=9645
Hey Dan, I also noticed on the product info page that there is a link to part 1 (of 3) on the video -- can you add links to parts 2 and 3 as well? (Somebody said the video just cut off, and I didn't realize where they were viewing it from...)…
