The CC-GPIO-AXI is a synthesisable Verilog model of a General Purpose Input/Output Controller. The GPIO core can be efficiently implemented on FPGA an ...

The PCA9554B and PCA9554C are low-voltage 8-bit General Purpose Input/Output (GPIO) expanders with interrupt for I²C-bus/SMBus applications. The only difference between the PCA9554B and PCA9554C is ...

General purpose input-output (GPIO) pins are the simplest peripherals. The link to an object under control (OUC) may become inadvertently unreliable due to many reasons: a loss of contact, short ...
