BCM2835 Peripherals BCM2835 contains the following peripherals which may safely be accessed by the ARM: One part of theses peripherals are routed from the BCM2835 chip pads to the 2×20 GPIO header in order to be freely accessible (as shown above). One other part of these peripherals are routed from Read more…
Purpose The main idea was to generate a configurable Pulse Width Modulated (PWM) signal out of a Raspberry PI Zero v1.3. The software solution The first solution was to handle a regular GPIO pin by software in order to alternate one and zeros via a loop. To do this, I Read more…
