GPIOsEdit
DescriptionEdit
i.MX6 can handle external pins in many different ways and most of them can be configured as GPIOs. When a pin is set as a GPIO, it is possible to read its value, change its direction or change output value directly from the shell.
Some GPIOs are available on J33 WIDE™ connector.
SignalsEdit
The following table describes some GPIOs signals available on J33:
| Pin# | SOM Pin# | Pin name | Pin function | Pin Notes |
|---|---|---|---|---|
| 28 | J10.191 | EIM_D26 | GPIO3_IO26 | |
| 30 | J10.193 | EIM_D27 | GPIO3_IO27 | |
| 32 | J10.50 | GPIO_17 | GPIO7_IO12 | |
| 34 | J10.40 | GPIO_6/I2C3_SDA | GPIO1_IO06 |
Device mappingEdit
GPIOs can be used directly on Linux kernel device driver or can be configured on the device tree.
Device usageEdit
See the GPIOs page on the DESK-MX6-L Software Manual.
