3.6 Peripheral Control
DLPC350 offers several configurable pins. The Peripheral Control tab of the GUI controls how these pins
are configured. The following options are available:
• General Purpose Clock: Two DLPC350 pins can be individually configured as clocks.
• PWM Output Setup: Two DLPC350 pins, GPIO_00 (pin 18 in J6) and GPIO_02 (pin 22 in J6), can be
individually set as PWM outputs.
• GPIO Configuration: Several DLPC350 pins can be individually configured as GPIO. Once configured
as GPIO, the Pin Direction (Input or Output), if set to output the Pin State (High or Low) and output
type (open drain output or drive high or low), can be configured. Some GPIO pins are already
configured by the firmware for specific functions and these are listed with their current configuration.
• PWM Capture Setup: Two DLPC350 pins, GPIO_05 (pin 14 in J6) and GPIO_06 (pin 17 in J6), can be
individually set as PWM inputs. These pins will sample at the frequency specified in PWM Sample
Rate and report the duty cycle of the input signal.
• I2C0 (Master) Read/Write Control: The DLPC350 master I2C0 port can be accessed via the J16
connector on the LightCrafter4500. This section provide control over this port. The hex addresses and
data should be in the format <value><space><value><space>... For example: 0x22 0x11. The number
for bytes to be read is input as a decimal value.
