  • POV Globe 24bit True Color and Simple HW

    A number of people have been building the POV Globe using my P8XBlade2.For those people, there is another way rather than re-programming the EEPROM.Format your microSD card, preferably FAT32 these days, else FAT16.Copy the OSv114sd.zip file (from Parallax forums) to your PC. Unzip them and copy those files to your microSD card. (use the sd not the sc zip file!)Copy the bitmap files from the Instructables article to your microSD card.Copy or Rename your POV binary file (the runtime file you would be programming into the EEPROM) to _BOOT_P1.BIN and then copy this file to your microSD card.Now when my OS boots, it will search for the _BOOT_P1.BIN file, and if it finds this, it will run it instead of my OS.This way, you don't even require the USB-Serial converter.BTW I have my LED string on...see more »A number of people have been building the POV Globe using my P8XBlade2.For those people, there is another way rather than re-programming the EEPROM.Format your microSD card, preferably FAT32 these days, else FAT16.Copy the OSv114sd.zip file (from Parallax forums) to your PC.

However, I will be overseas for a month from next week so it probably will not happen until I get home.

    I have not supplied the P8XBlade2 with 5MHz xtal. It uses a tiny surface mount crystal 2.5x3.5mm IIRC. There are via holes that can take a watch can 5MHz xtal provided the 12MHz SMT xtal is not mounted, or a track is cut on the underside between the via and xtal.Perhaps you used the CpuBlade which does not have the microSD socket?

    When using my P8XBlade2 you will need to change the clocking as I overclock the CPU. In POV Globe_I_0_1.spin change the clock settings from:_clkmode = xtal1 + pll16x _xinfreq = 5_000_000to:_clkmode = xtal1 + pll8x _xinfreq = 6_000_000It is not necessary to have/modify the clock settings in the sub-objects FAST_ASM_xxxx.spin files as only the top object settings are used.I have attached the modified source and binary and eeprom files.Enjoy :)Note: I have updated my website and some older links have broken. Please use www.clusos.com and follow the links.

    I this USB-Serial CP2102 6pin version US$1.25 - It fits my P8XBlade2 by just bending the DTR pin to the next 0.1" position. This is shown on the Parallax Forum.http://www.ebay.com/itm/6Pin-USB-2-0-to-TTL-UART-M...If you use a P8XBlade2, don't forget you may need to enable the WE to the EEPROM (solder link), and you will need to solder the QE link (enables the onboard transistor reset circuit from DTR) if you use a non-PropPlug USB-Serial otherwise you will need to solder the other side of the 3pin link for PropPlug compatible.

    Very nice project. Congratulations!!!I love the idea of 3D printing the ring for the LEDs.
