Step 5: Testing Code Download

In this section, we'll run through a series of short tests to make sure that the LameStation is able to download code.

Instructions

  1. The first thing you should do, before you try to program, is test and make sure the power still comes on when you power on the board like before. If you've already forgotten, see the power-on test for more information.

  2. Then comes the pivotal moment when you find out if you did it right. This will verify your ability to download code to the Propeller. Make sure the board is powered off, then install the Propeller only back onto the board.

  3. Get out the serial programming cable that came with your kit.

  4. Plug the USB end of the cable into your development computer.

  5. Plug the other end to the serial port on your LameStation.

  6. Do another power-on test to make sure that there are no shorts. Leave the board on for the duration of this step.

  7. Download and install the LameStation SDK if you haven't already.

  8. Go to "File -> Open":

  9. Look in the demos/assembly/ folder of the LameStation SDK (wherever you installed it) and open the ImAlive.spin program.

  10. Press F10 to start code download to the Propeller.

    The following box will pop up briefly to indicate the download has started.

    Please see Troubleshooting Code Download if you are having problems loading the ImAlive.spin program.

  11. The resulting blink pattern will be the same as in the previous section, when the ImAlive program was loaded off the EEPROM, but now, there is no EEPROM. The light is blinking because you downloaded the code directly to the Propeller itself.

  12. Now try turning off the board and turning it back on. You'll notice the light has stopped blinking. This is because the code was running from memory, and is lost when the board loses power. But fear not! You can reload it at any time! Open up SimpleIDE and re-run ImAlive, and it will be back and blinking again, good as new!

  13. After the test is complete, we should remove the Propeller chip again as we explained in Step 1: IC Extraction.  We don't want to overheat it or damage it when we continue soldering.  Remember to be very careful so no pins are bent, and use your ESD foam to protect the chip after you remove it.
