GPIO programming
The table below shows which Intel QM57 (“Ibex Peak”) GPIO is wired to the appropriate System Panel
Connector (X5) pin. For further information please consult the “Intel® 5 Series Chipset and Intel® 3400 Series
Chipset External Design Specification (EDS)”.

Windows
In order to use the GPIOs under Windows you may utilize the PortTalk driver.
Note: The following description on how to use the PortTalk driver is based on
an extended version created by LiPPERT ADLINK Technology. To get it,
just send an email to
[email protected]
.
The “Cmdline tools” directory contains all available functions provided by the PortTalk driver. The functions
needed are “rdpcil”, “wrpcil, “inl” and “outl”.
Initially the GPIO Base Address is needed. It can be found in register 0x48 of the PCI Configuration Registers
(LPC I/F—D31:F0). Using the command line you have to type “rdpcil 0 31 0 0x48”. In the example, which is
shown in the picture below, the readout is “0000 0501”.
