HD44780 LCD with PWM LED Backlight control

And voila! As I said in one of the last two posts (Initial post: http://hsel.co.uk/2014/08/14/stm32f0-discovery-board-and-the-hd44780-lcd/ and integrating a charge pump for backlight control: http://hsel.co.uk/2014/08/14/stm32f0-discovery-board-with-hd44780-and-integrated-charge-pump/), I’ve now included a generic LED backlight PWM controller using one of the standard GPIO pins. 239 more words
