Frequently Asked Questions
The Serial LCD/GLCD Adapter Board enables you to easily connect your GLCD 128x64px and LCD 2x16, 4x20 character displays to your board and save MCU pins. A 16-bit I/O expander MCP23S17 is provided on the board thus decreasing the number of MCU pins needed for running this display. Expander features SPI(tm) clock speeds up to 10 MHz for higher throughput applications. Board is equipped with a long flat cable with IDC10 female header connector, which is compatible with all mikroElektronika development boards.
IC/Module: MCP23S17 16-bit Bidirectional I/O Port
MCP23S17 is a 16-bit remote bidirectional I/O port featuring SPI clock speeds up to 10 MHz for higher-throughput applications. It comprises of multiple 8-bit configuration registers for input, output and polarity selection. The 16-bit I/O port functionality consists of two 8-bit ports: PORTA and PORTB. It has two interrupt pins (INTA and INTB) that can be connected with their individual ports, or can be logically ORed together in order to activate the pins in case either port triggers an interrupt.
