This section describes the differences between GPIO APIs of MCU+ SDK and Processor SDK RTOS (PDK). This can be used as a migration aid when moving from Processor SDK RTOS (PDK) to MCU+ SDK.

In MCU+ SDK, the GPIO APIs are simplified. Most of the CSL and LLD are merged into single API. Refer GPIO for more details.

API changes

There are changes in functions names, structure names and macro names. The changes in function names are listed below.

PDK	MCU+ SDK	Change Description / Remarks
GPIO_setConfig	GPIO_setDirMode	In MCU+SDK, this GPIO_setConfig is separated into sub APIs such as GPIO_setTrigType, GPIO_setDirMode.
GPIO_write	GPIO_pinWriteHigh	API rename along with interface parameter changes.
GPIO_write	GPIO_pinWriteLow	API rename along with interface parameter changes.
GPIO_read	GPIO_pinRead	API rename along with interface parameter changes.
None	GPIO_pinOutValueRead	In MCU+SDK, this API can be used to determine the output logic level(value) on a specified GPIO pin.
GPIO_setConfig	GPIO_setTrigType	In MCU+SDK, this GPIO_setConfig is separated into sub APIs such as GPIO_setTrigType, GPIO_setDirMode.
None	GPIO_bankIntrEnable	In MCU+SDK, this API can be used to enable the bank interrupt.
None	GPIO_bankIntrDisable	In MCU+SDK, this API can be used to disable the bank interrupt.
None	GPIO_getIntrStatus	In MCU+SDK, this API can be used to determine the enabled interrupt status of a specified pin.
GPIO_clearInt	GPIO_clearIntrStatus	In MCU+SDK, this API can be used to clear the enabled interrupt status of a specified pin.
None	GPIO_getBankIntrStatus	In MCU+SDK, this API is used to return the interrupt status of the specified bank.
None	GPIO_clearBankIntrStatus	In MCU+SDK, this API is used to clear the interrupt status of the specified bank.
GPIO_disableInt	None	In MCU+SDK, Bank interrupt disable is available instead of specific pin.
GPIO_enableInt	None	In MCU+SDK, Bank interrupt enable is available instead of specific pin.
GPIO_init	None	Removed as abstraction is done with simplified APIs.
GPIO_setCallback	None	Not Applicable.
GPIO_toggle	None	None

Important Notes

In MCU+ SDK, users are recommended to use SysConfig as this will greatly simplify the task of driver configuration.
