How Sean gets ready for RPi k-deving & How Sean started the skeleton of the hardware PWM kernel module. But wait, there’s more! Poking at /dev/mem – hacking without a net! Before writing up the PWM kernel module, Sean wanted to spend some user-space time prodding the registers for PWM. The fastest way to do this is to simply open up /dev/mem and index to the PWM control registers. This isn’t for the faint-of-heart, as a little incorrect math and you can possibly bork your Pi installation but it is as fast & furious as it gets with embedded Linux.
