SX Specific Pulse Width Modulation

Methods:

• PWM demo by Nikolai Golovchenko
• Dan Michaels PIC/SX RAM Table based PWM
• Scott Dattalos 8 channel parallel PWM
• A Virtual Peripheral DAC: Implementing Pulse Width Modulation (thanks to Randy Glenn for recovering it!)
• pwm.src The original 8 channel 8 bit PWM virtual peripheral for the SX28 with a date code of AB9921AA (or later) requires the SXKEY28L.exe software for assembly and programming. (thanks to David Carrier for recovering it!)
• pwms.src The original 8 channel 8 bit PWM virtual peripheral (thanks to Randy Glenn for recovering it!)

Integrations:

• 8vp.src: Two PWM outputs, 19.2kbaud UART, two 8-bit A/D converters, one I2C serial link for EEPROMs, two 16-bit independent timers, Time clock (keeps count in msec), a software execution path switcher and push button detection and debounce. SX Demo Enhanced 2.0 by Craig Webb of Parallax Inc.
  
• SXDEMO: Two PWM outputs, 19.2k baud UART, two 8-bit A/D converters, one I2C serial link for EEPROMs, two 16-bit independent timer, and all implemented as Virtual Peripherals, in software. This is compatible with the SX Demo Board from Parallax, and is the same code is shipped with the Parallax tools.
  
• POWERVP: Four PWM outputs, 19.2k baud 6 port UARTs, four 16 bit timers, and two 8 bit A/D converters. This is not compatible with the SX Demo Board from Parallax, but is a very impressive demonstration of the type of power that software can provide on the right kind of silicon.
  
• SX52 based audo recorder / player with MMC FLASH memory
