STMPE821
Basic PWM controller
41/55

Basic PWM controller
The advanced PWM allows complex brightness and blinking control of a LED. The basic
PWM controller allows simpler brightness control and basic blinking patterns. The
STMPE821 is fitted with a 4-channel basic PWM controller.
The PWM controllers outputs are connected to the GPIO 0-3. In order to activate the PWM
channels, the alternate function bits in the master enable register must be set to '1'. The
PWM controllers are capable of generating the following brightness patterns:
Figure 10.
Pulses with programmable brightness, ON/OFF period and repetition
On period = period 0[1:0] * time unit [3:0]
Off period = period 1[1:0] * time unit [3:0]
Duty cycle during “on period” = brightness [7:4]
Number of cycles = repetition [3:0]
Ramp mode is disabled
