- A USB Bootloader is now used. Use either the bootloader host supplied with PSoC Creator 3.0, or else the standalone app included with Cypress AN73503. You have 2 seconds between connecting the USB cable and hitting the "program" button. - The bootloaderhost program included in this repository doesn't quite work yet. When functional it should simplify firmware updates on Linux and Mac OSX - Fixed an error in the parts spreadsheet which had a 22k resistor for USB termination instead of a 22 Ohm resistor. - Updated parts spreadsheet with part number of PSoC actually used (CY8C5267AXI-LP051).
