WP8 bluetooth RGB LED controller with pic12f1572 16bit pwm

Tuesday, September 9th, 2014

Diego shares his latest project a WP8 bluetooth RGB LED controller with pic12f1572 16bit pwm in the forum: I made a Bluetooth board card with a pic12f1572, this pic can drive 3 output pwm at 16bit. Project files are available at Github. Via the forum.

App note: High resolution RGB LED color mixing

Saturday, March 22nd, 2014

This application note from Microchip demonstrates color mixing using the PIC12F1572 MCU (PDF!): This application note demonstrates color mixing using the PIC12F1572 processor. The PIC12F1572 processor features three 16-bit pulse-width modulators (PWMs), among other peripherals. The 16-bit PWMs allow precise control over each RGB LED, allowing smooth transitions even at low-brightness/luminosity levels.

  • Drone: So these go for around $330 USD and NO published calibration procedure online or otherwise? Given what's inside - I don't think I'll be considering...
  • Pekka Akselin: This is ridiculous!? :-) We are back at 256(!) byte EPROMs that needed multiple, a handful, of voltages to run! :-(
  • KH: Let's try a back-of-envelope calc balancing energies. From MCP1700 datasheet, there are graphs for a 200mA load step. Estimate the energy shortfall as 12uJ. Say...
  • Daniel: It's been a week and my comment is still awaiting moderation. Apparently the CIA doesn't want their involvement known?
  • KH: Agree, so okay, I guess he must have learned from somewhere. 100nF and 1000uF is so far apart, that was jarring; it's more magic incantation...
