41 / 55 page  STMPE821 Basic PWM controller 41/55 10 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 Figure 11. Ramps with programmable brightness, ON/OFF period and repetition Duty cycle Time On period Off period ON period Off period 1 time unit CS00054 Duty cycle Time ON period Off period ON period Off period 1 time unit CS00055 |
