Target Category: STM32
Target Sub-Category: GPIO
Description: The GPIO Output block outputs digital data.
Bit Width: Specifies the number of contiguous bits to read in.
Channel: Indicates the channel number.
GPIO Mode: Configures the output as push-pull or open-drain.
Push-pull mode: When a logical 1 is presented,
the upper switch turns ON and the lower switch turns OFF. When a logical 0 is
presented, the upper switch turns OFF and the lower switch turns ON and ties the
output pin to ground.
Open-drain mode: 0 ties the output to ground; 1
leaves the output floating (Hi-Z state). In this case, the voltage is defined by
the pull up or pull down resistor setting.
Always try to apply the lowest amount of voltage to minimize power usage.
Offset: Specifies the offset into the digital port register.
Port: Specifies the digital register.
Pull up/down: Performs the selected action:
Pull Up: Turns the upper resistor ON and ties
the pin to VDD.
Pull Down: Turns the lower resistor ON and ties the
pin to ground.
None: Neither resistor is activated.
Speed: Indicates the speed of GPIO output power switches. For more information, consult the STMicroelectronics device specification sheet.
Title: Indicates the channel title.
