The pull- up or pull- down resistors independently configured for any io pin may remain active while entering a low- power mode. The purpose of this document is to describe step- by- step how to use the microcontroller’ s pins as general purpose input/ output ( gpio) on microchip tinyavr® 0- and 1- series, and megaavr® 0- series devices. 1 purpose of the peripheral the general- purpose interface combines four general- purpose input/ output ( gpio) modules. Long and short button press:. Generally there are multiple gpio pins on a single mcu for the use of multiple interaction so simultaneous application.
About this manual this document describes the general- purpose input/ output ( gpio) peripheral in the digital signal processors ( dsps) of the tms320c6000 dsp family. Notational conventions this document uses the following conventions. These pins can be configured for the following applications:. This provides a low- latency direct path to change the state of outputs or to read the state of inputs. Hexadecimal numbers are shown with the suffix h. The following use cases are presented: blink an led: blink an led using a delay, toggling the led every 500 ms.
Gpio pins can act as external interrupt request inputs and trigger the operation of peripherals by acting as producers for the prs. Each gpio module provides 32 dedicated general- purpose pins with input and output capabilities; thus, the general- purpose interface supports up to× 32) pins. The purpose of this document is to describe step- by- step how to use the microcontroller’ s pins as general purpose input/ output ( gpio) on microchip tinyavr® 0- and 1- series, megaavr® 0- series and avr® da devices. Introduction a general purpose input/ output ( gpio) is an interface available on most modern microcontrollers ( mcu) to provide an ease of access to the devices internal properties. The following use cases are presented: blinks a led: blinks a led using a delay, toggling the led every 500 ms.
Int_ even int_ odd device compatibility device compatibility this application note supports multiple device families, and some functionality is different depending on the device. The pins can be programmed as input, where.
