●
SPI : 100 kBit/s, 250 kBit/s, 1 MBit/s
●
I2C : 100 kBit/s, 400 kBit/s, 1000 kBit/s, 3400 kBit/s
●
CAN : 50 kBit/s, 100 kBit/s, 1 MBit/s
●
LIN : 9.6 kBit/s, 10.417 kBit/s, 19.200 kBit/s
Active
Sets the polarity for the UART bus.
16.2.7 Settings for PWM signals
You can use the pattern generator to generate several pulse width modulated (PWM)
signals: PWM, PWM - RGB LED, PWM-TestSignals.
● PWM signals ......................................................................................................... 420
● PWM - RGB LED signals ...................................................................................... 421
● PWM test signals .................................................................................................. 422
16.2.7.1 PWM signals
Access: "Menu" > "Pattern Gen." > "Pattern" = "PWM"
You can use the generated signal to control a motor driver directly, for example.
Frequency
Sets the frequency of the PWM signal.
Remote command:
PGENerator:PATTern:FREQuency
on page 790
Duty Cycle
Sets the duty cycle of the PWM signal at P0. Change the duty cycle using the Naviga-
tion knob to increase or decrease the motor speed.
