  • Sorry,! We should have packed a USB cable. I don't think it occurred to any of us.

    Here is a link to the ROM Monitor/Debugger commands, SD boot, and more TAQOZ info
    Don't forget - the Monitor/Debugger/SD routines can be called from your PASM programs. So you can use these to send/receive serial :smiley:

  • Is it OK to publish a video of a P2 in action on YouTube? Else, how to get a video file to show up here in the forum?

    You can upload MP4 files that are under 10 megabytes.

    Yeah, every app that I've got wants to export the .mov file into an .m4v, which the forum SW doesn't seem to like... Oh well:-)

    I tested that board just a few days ago. Glad they are getting out into the world now.
  • Try "greater than, space, escape" and TAQOZ should greet you. ( $3E, $20, $1B )
    To make any led blink such as P0 type "0 BLINK"

    I finally found a micro usb and was waiting for TAQOZ to show up as final choice when nothing else is going on.

    Why is that greater than, space, escape needed?

    Anyways my P2 works and I do have a TAQOZ# on my Parallax Serial Terminal.

    Time to explore...

  • The next boot ROM will pack a lot more TAQOZ into it and hopefully we can have it boot directly into TAQOZ if no other boot method is found rather than simply putting the chip to sleep to save batteries as was the case with P1. However TAQOZ could still indeed have sleep timeout on it if Chip still requires this feature. If boot sequencing falls through to TAQOZ then it can have its own higher level boot methods in regards to Flash and FAT32 SD etc.

    Yes, there is something totally unique about the bit sequence in "> ", even with a variable gap between the two characters, that allows definite baud detection.

    I am running around and checking boxes, NO micro USB cable anywhere, why not the same as used for the PropPlug, could have fit.

    Damn.

    Mike

    microUsb is more common these days. and more importantly, more robust than miniB. In case of damage, it's the cable plug that will usually fail, instead of the socket. Always easier for a customer to replace a cable. That's the thinking.

    As for you not having one, that's annoying.

    We did add the cable and SD card as optional items at the product page, right below the eval board. And the text stated they were not included.

    Point taken that the info was easy to miss when purchase speed was priority!

    So glad many of you are getting boards for Chipmas!

    Are you saying it doesn't work with just the power from the USB connection? It requires a separate power supply?

    I just tested it with my desktop and had no issues. It could be the usb cord I was using too. I have some low quality cables I should just throw away already.

    correct. Aux psu not required for moderate current use. The PC usb port will typically be able to supply 500mA. Using a powered hub recommended if your PC ports are already heavily loaded!

    As I could understand, the issue with entering Taqoz from the terminal was the wrong autobaud sequence used. Not a usb or power connection issue.

    I think we need a list of first steps connections and scripts put in one place.

    Ah.. seems @Cluso99 has done that a couple posts above. Fantastic. Cheers.

    It was a couple issues, I was using the wrong sequence first but I also had a bad usb cable. I noticed the led brightness increase when I plugged in the brick. I've also noticed some of my usb devices have a "weak power on" sequence. IE when plugged in, leds are dim until port is enumerated. I did consider ordering a USB cord, I guess hindsight's 20/20.

    The main issue was a failure to RTFM! Funny thing is I read the paragraph with the sequence to enter TaqOZ more than once.. Blame the excitement. TaqOZ is pretty well documented, just trying to get my head around it right now. Just playing with blinky leds but I'm very happy we have this interactive REPL. It should make things really easy to test once I understand it a little better.

    You can convert m4v to mp4 via VLC.

    That's what I thought... But, when I set mp4 as the exported type, I get mv4 and the forum won't let me attach the file.

    Yes- those LEDs are powered by the 5V rail to reduce switching current interferences on common 3V3. The PC power source would usually drop a little more voltage than aux, hence the brightness difference. Well spotted! Maybe that's a feature to determine power src!
  • Thanks for the updates all!

  • Is the Goertzel add on module supposed to help with Voice Recognition?
    There is no such thing as bad news.
  • The USPS now says my P2-ES board will be delivered tomorrow!

    Ditto. I should be a Chipmas!
  • Is the Goertzel add on module supposed to help with Voice Recognition?

    Not really. It's for cyclical measurements when you want to measure phase/delay or amplitude, especially when coupled to its own reference. It will have lots of uses, but for something like speech, ADC's and software would be better.

    Try just changing the extension to .mp4 and see if that works.
  • That probably will work. Browsers will render it, or at the least, offer it for download.

  • Mine is already under way. Since I'm in Portugal, I'll get it in January. Probably it Will be served with an hefty customs charge, but I don't mind.
