  • MyHDL examples for LogiPi

    mjonesmjones
    Hi @woolfel

    We do not have any logi-pi specific examples using myhdl, but it should be straightforward to convert any other examples you find to work with the logi-pi.

    Here is a full workshop on using myhdl.  https://bitbucket.org/cfelton/pyohio

    You will just need to make sure use the logi-pi ucf file when building the generated HDL.  Then use the logi-loader after you have built the example.  

    Hope this helps.

  • Programming SPI Flash

    mjonesmjones
    Yes, the chip did successfully program - then tries to configure itself, but fails of mode pin is not set correctly.

    The manual probably needs to be updated.  I think the older version boards mode pins were defaul slave config.  We have changed to to default self config so that the board can be used in standlone mode with no changes.  The GPIO expander then controls the mode pin if using the slave config from the Pi.  

    Hope you are able to get to the fun stuff now :).

  • LOGI-PI-2

    @tmbarton

    The first boards off the latest MFG line have been shipped to e14/farnell.  The stock should be updating soon.  This is a small initial QTY, which will be followed shortly by a large amount of stock.  We hope to not have any further gaps in availability.

    @myriaddev  I will post a formal doc shorty with the described differences.  The changes are very minor and we are calling the board R1.5 in our documentation to reflect this.  Perhaps we will call it "2" to avoid confustion with the E14 nomenclature, but we were unaware of the naming that E14 would use at the time.  

    Brief breakdown of changes:
    - FCC/CE class B approved
    - micro-usb connector to supply any extra power needed that the Pi/bone cannot supply- the connector is PWR ONLY - not usb (did not want to add cost)
    - added i2c gpio expander to handle IO configuration of the FPGA - dedicated Pi pins no longer needed and can be used elsewhere
    - removed Pi SPI pins from the shared FPGA/Flash pins so that the FPGA can freely access flash and communicate with the Pi with no conflict
    - minor change to form factor - added B+/2 mounting holes (kept A/B holes as well)

    You can see the full schematics on the repository under R1.5.  

    Cheers.

    HI Bruce,

    Sorry for the wait! 

    As far as we are aware the price will continue to be $89.  It must have been a mistake of them entering the prices in pounds rather tha US $.

    The boards have now finished FCC/CE and are being MFGd.  We are pushing for the end of the month for them to be back in stock.  

    Cheers!
