DHWCtrl.GpioSetState

Drive an already-configured output pin to the requested Level.

Properties

Parameters (request frame)

Name Type/Size Description
Pin.Port Enumeration (8 bits) GPIO bank letter (A..Z).
SoC-native GPIO bank identifier. The keyword letters mirror the bank designators on STM32-style parts; not every part implements the full A..Z range. The firmware rejects banks it doesn't support with ErrInvalidParam.
Values (26):
  • A (0x00)
  • B (0x01)
  • C (0x02)
  • D (0x03)
  • E (0x04)
  • F (0x05)
  • G (0x06)
  • H (0x07)
  • I (0x08)
  • J (0x09)
  • K (0x0A)
  • L (0x0B)
  • M (0x0C)
  • N (0x0D)
  • O (0x0E)
  • P (0x0F)
  • Q (0x10)
  • R (0x11)
  • S (0x12)
  • T (0x13)
  • U (0x14)
  • V (0x15)
  • W (0x16)
  • X (0x17)
  • Y (0x18)
  • Z (0x19)
Pin.Number Integer (8 bits) Pin number within the bank. Practical range is SoC-specific (typically 0..15 on STM32). Named Number rather than Index to avoid a NameChecker collision with the peripheral-instance Index in ListPeripherals's Pins array (struct parents don't currently participate in field-name namespacing).
Level Enumeration (8 bits) Target output level to drive.
Logic level of a single GPIO pin.
Values (2):
  • Low (0x00)
  • High (0x01)
