uLCD-220RD Display Module 4D SYSTEMS uLCD-220RD Display Module 4. Hardware Interface - Pins The uLCD-220RD Module provides both a hardware and software interface. This section describes in detail the hardware interface pins of the device. 4.1. Serial Ports – TTL Level Serial The DIABLO16 Processor has three hardware asynchronous serial ports (COM1 – COM3) that can be configured on a variety of the processors GPIO pins. TX/RX0 (COM0) is dedicated and its pins are fixed.

uLCD-220RD Display Module 4D SYSTEMS uLCD-220RD Display Module 4.7. Pulse Out however vary, and the DIABLO16 PWM control can be adjusted to suit most applications. Pulse Out is used to create a single pulse of set duration on the selected pin of choice, which is inverted in polarity to the current state of the pin. This ‘inversion of polarity’ means if a Pin is currently held HI, and Pulse Out is executed on that Pin, the pin will pulse LO and then return to HI.

uLCD-220RD Display Module 4D SYSTEMS uLCD-220RD Display Module 4.10. Quadrature In There are two Quadrature Input channels available on the DIABLO16 processor, which requires 2 GPIO pins each. Please refer to the table on the previous page for details on which GPIO can be configured for Quadrature Input. Quadrature Input allows a quadrature encoder to be connected, and the position counter and delta counter can be read at any time.

uLCD-220RD Display Module 4D SYSTEMS uLCD-220RD Display Module 5. PmmC/Firmware Programming 6. Module Features The DIABLO16 processor is a custom graphics processor. All functionality including the high level commands are built into the chip. This chip level configuration is available as a PmmC (Personalitymodule-micro-Code) file, which can be likened to traditional Firmware.
