    David,
    That's why the reset pin has a jumper ;)
    For development wire in a switch to Gnd to reset when the test program crashes. Otherwise no need to manually reset as the reboot command can perform a soft reset.

    I have worked on it before and picked this up again yesterday. I need to get it running to move forward with debugging marks Sphinx compiler that I have been working on.
    So it sounds like you're looking for code that can parse the incoming download from the PC. Can't you just use the same code that is in the ROM but modify it to write to an SD card instead of hub memory? I think Chip provided the source code for the P1 ROM.

  • David,
    That is exactly what I have been doing ;)
    Haven't got it working yet though :(

  • Cluso...it has already been said in various ways by others but, WAY TO GO!! I absolutely love this new addition to the P1 family. :)

    As for a possible SX board, atm I'm sorely tempted to make my own (using dirtyboards.com). I'd like to see how many SX-48 header boards can fit into 100 square centimeters. Clearly they won't be anywhere as nice or as professional as your new P8XBlade2 but they may at least allow me to use SX chips once again for those simple embedded control tasks that come along every day.

    User Name,
    Thanks for your kind comments. I am very pleased that you like my little board.

    I built it for the 1 square inch hackaday contest and then read the entry requirements and found that not only did it need to be 1 sq in or less (that's why the board is 0.78x1.28" and not 0.8x1.3") and then found the extra requirement of fitting in 1" x 1" square :(

    FYI the connections are still on a 0.1" pitch - I just trimmed the outer board edges.

  • @Cluso99, Will your P8XBlade2 board always be available? I would like to buy at least two, but it will have to wait till, I can climb out of the Christmas money pit I fell into. >:(

  • MikeDYur,
    Yes. I have plenty of pcbs and can always have more made.
    I still sell RamBlade and I made those pcbs in 2009. I don't carry the CpuBlade any more but I can always have pcbs made by oshpark if needed.

    Cool. That was going to be my question. I think I might just standardise on this board.

    PropBASIC ROCKS!
  • I have a couple of boards based on my P8XBlade2 design. The P8XBlade2 layout sits near the centre of a larger pcb which has other things on it.

    I am just tweeking the prototype board layout which is 2"x2". It just a P8XBlade2 with some prototyping area. Hope to get if off for production later today.

    And then I have to complete the next 2"x2" that it's featured on.. Has TV, VGA, Kbd, Mouse, 2 channel audio out, 2 channels of Sigma-Delta (prop) ADC, a couple of uncommitted LEDs, a USB direct connection with auto-config pullups/pulldowns, and of course the P8XBlade2 (with microSD) in the centre. It's almost done. Just a few tweeks left so hope to get it off sometime next week.

  • I got mine too! Actually, I got it a few days ago, but haven't had the time to start playing with it. :{
  • Just tried hooking up my board. Should I be able to identify the Propeller chip if I just hook up GND, 5V, SI, SO, and reset to a USB2serial adapter? Or do I have to do something to enable reset?

    What should I expect to see on SI/SO if I just connect a terminal program? Can I do anything without a PropOS SD card inserted?

    Thanks,

  • Thanks guys, and thanks for posting what happens David.

    There are two sets of links on the P8XBade2 that you should be aware of..

    WE
    This two pads need to be shorted to program the EEPROM. PropOS has a "PROGRAM <sourcefile> WL/WU" to program the EEPROM. You can also download to eeprom. Both require two WE pads to be shorted - you can put a solder blob on this if you wish, or buy a 0.050" pair of pins and a 0.050" shunt (both expensive) and solder - be careful as the pins will only go thru to the other side of the pcb but there is the eeprom on the other side (a consequence of tiny boards!). BTW I program your boards using a piece of wire to short (its a little better than this but you get the idea - I just hold it on by hand and do a download to eeprom.

    QE - reset circuit
    On the P8XBlade2, there is a 3 pad set of links. The centre is the common. The QE marked pair (centre to edge of pcb) when shorted use the onboard transistor reset circuit (ie non PropPlug usb-serial boards). When the other pair (centre to inner pcb) are shorted, the reset circuit bypasses the transistor reset (ie for PropPlugs with inbuilt transistor reset circuits). When all 3 pads are open, off-board reset from the *R pad close to SO is isolated, but the *R pad beside the centre pad remains connected to the props reset line (you can see it is joined to the centre of the 3 pads). You can use this *R pad and ground to install a reset switch.

    David,
    You asked a question recently that made me think. I remembered that on my RamBlade I use a basic booter in ROM that looks for a BOOTPROP.BIN file (or AUTOEXEC,BAT) on the SD card.
    But on PropOS I actually program & run the _OS.CMD (_OS.binary) from EEPROM. I do need to change this as some updates will require EEPROM changes and this I was trying to avoid like I do on the RamBlade.

  • I ordered a couple because they are neat little boards but I want to make sure I understand a couple of things first.


    1.) In order to use standard tools that program the EEPROM I will need to solder-blob the WE jumpers together on the top of the board. Once I have programmed the EEPROM I can't get PropOS back onto the board. Correct?


    2.) I also need to jumper R to the directly connected RST side so the PropPlug can reset the Prop to begin the download?


    3.) Can I safely supply 3.3V directly while leaving 5V unconnected?

    Yes, either solder-blob or put a fine wirebetween the two WE holes (the wire will not go totally thru the board because of the eeprom underneath. The blob method is probably the easiest although you can use a component wire offcut and solder in place.
    The _OS.CMD file can be re-programmed into the eeprom to get PropOS back.
    2.) I also need to jumper R to the directly connected RST side so the PropPlug can reset the Prop to begin the download?
    Yes. This is the 3 pin jumpers labelled QE (near P17). You need to link/solder-blob the middle pin to the pin towards the centre of the board (ie not the QE marked pair which enables the transistor reset circuit since this circuit is on the PropPlug).
    3.) Can I safely supply 3.3V directly while leaving 5V unconnected?
    It is preferable to supply 5V and use the regulator. Some regulators cannot handle being supplied power on the output (3V3) side, so it is generally a bad idea.
    These days there are a lot of 5V supplies for phone chargers as well as using 5V from USB.
    Having said all this, if you link 5V to 3V3on the board and then supply 3V3 everything should be fine.

  • Thanks for the clarifications. These look like an easy way to drop a Prop onto a board design. Looking closer at the pin layout the 3.3V question is moot anyway. The position of the GND pin means I will have to put female headers on it to jumper in power anyway. Looking forward to playing with these.

  • Rosco, sorry I am away house sitting until Sunday evening and don't have a board or pcb layout with me. The rip 40 pin header is across the top. Some of the more useful rip pins such as txt and red and a rew I/o have tracks to the visa just below the header IIRC. You will also need to link the Gnd pin(s) which I also believe are tracked to via(s). Depending on the power source, you might want to connect the 5V lines too.

    Otherwise, you can just wait till I get home to post the precise details.

  • The P8XBlade2 has made it onto my P2 development board initially as a "boot assistant" but in parallel with all the other relevant I/O to maybe take over in the meantime as I am not confident about using the BemicroCV-A9 FPGA board for a unit that needs to be installed on-site for reliable 24/7 operation. I used the P8X mainly because it had plenty of I/O unlike my little P8 module which were designed mainly for the IoT5500. I am running an IoT5500, twin SD, quad RS485 using my ping-pong prototcol and a few other devices and modules.

    Here's a shot of the P2 board with the P8X installed (The IoT5500 and some other modules were vacated for testing).

  • Nice Peter.
    I wonder if you could fit your parts on my other version that has a prototyping section on it?
    See page 1 a few posts down for a pic. It also has an Arduino footprint header (unconnected) and Raspberry Pi (unconnected) at the top. Also has footprint for microUSB broken out which needs the middle of the Raspberry Pi section cut out. I have a few of these pcbs as I had 10 made. Note the microSD is on P8-11 and not P12-15 as on the P8XBlade2.

    Do somebody have a component library for use in diptrace or eaglecad for this beauty P8XBlade2 ?
    I am waiting for some tryouts P8XBlade2 from post, but wants to draw my pcb interfaces already

    Thanks
  • I haven't posted the pcb files but they are not in dip trace format.
    I am guessing you want to make an expansion pcb and not a P8XBlade2? If so, the large holes are all on 0.1" grid and the pcb is just under another 0.05" beyond the pad centres. Does this help?

    How to connect the 6-pin USB to TTL Serial CP2102 to my P8XBlade2 board

    Available for $1.25 here http://www.ebay.com/itm/6Pin-USB-2-0-to-TTL-UART-Module-Serial-Converter-CP2102-STC-Replace-Ft232-Module-/401092508083?hash=item5d62f9f9b3:g:2aQAAOSw0kNXhzR7

    P8XBlade2_CP2102.jpg

    You can use any of...
    1. Solder a 6-pin 0.1" pitch socket (remove/cut pin 5) on the P8XBlade2, and plug in the CP2102 board when required
    2. Solder a 6-pin 0.1" pin header (remove/cut pin 5) on the P8XBlade2, and connect the CP2102 by female/female jumper wires
    3. Solder the CP2102 board pins directly to the P8XBlade2

    NOTE:
    When using the PropPlug, you need to link the "transistor bypass link" which joins the opposite end to the centre pin of the 3-pin QE links. Otherwise, the RESET pin is disconnected from the Propeller chip. (see circuit diagram on page 1 of this thread).
