This article explains how to program a Microchip PIC microcontroller on a Macintosh running OSX. The programmer hardware that is used is a Wisp628 by Van Ooijen Technische Informatica. The software consists of two parts, JAL and XWisp. JAL is an open source, high-level language that is used to generate a PIC compatible hex file. XWisp is Python-based, open source software that is used to upload the hex file from the Macintosh host via the Wisp628 programmer board to the PIC microcontroller. The article explains how to compile JAL for MacOSX, how to create a connection from the Mac via the Wisp628 programmer board to the target circuit containing the PIC, how to upload a hex file using XWisp, and how to create a simple LED flashing program.
