GPIODCF(4) - Device Drivers Manual # GPIODCF(4) - Device Drivers Manual NAME # gpiodcf - DCF77 timedelta sensor through GPIO pin SYNOPSIS # gpiodcf* at gpio? offset 0 mask 0x1 gpiodcf* at gpio? DESCRIPTION # The gpiodcf driver decodes the DCF77 time signal code using one GPIO pin. The pin is used as a data signal. The GPIO pin must be able to read an input. The pin number can be specified in the kernel configuration with the offset locator. ...
GPIOIIC(4) - Device Drivers Manual # GPIOIIC(4) - Device Drivers Manual NAME # gpioiic - GPIO I2C controller SYNOPSIS # gpioiic* at gpio? offset 0 mask 0x3 flag 0x0 gpioiic* at gpio? iic* at gpioiic? DESCRIPTION # The gpioiic driver allows bit-banging an I2C bus as a master using two GPIO pins. By default the first pin is used as a serial data (SDA) signal and the second as a serial clock (SCL). ...
GPIOKEYS(4) - Device Drivers Manual # GPIOKEYS(4) - Device Drivers Manual NAME # gpiokeys - GPIO keys SYNOPSIS # gpiokeys* at fdt? DESCRIPTION # The gpiokeys driver handles events triggered by GPIO keys. Currently, only lid status events are supported. The lid status is set up as a sensor and can be monitored using sysctl(8) or sensorsd(8). SEE ALSO # gpio(4), intro(4), sensorsd(8), sysctl(8) HISTORY # The gpiokeys driver first appeared in OpenBSD 7. ...
GPIOLEDS(4) - Device Drivers Manual # GPIOLEDS(4) - Device Drivers Manual NAME # gpioleds - GPIO LEDs SYNOPSIS # gpioleds* at fdt? DESCRIPTION # The gpioleds driver provides support for LEDs connected to GPIO pins. Currently, LEDs are only set to their default state, e.g. to indicate the power status of the system. SEE ALSO # gpio(4), intro(4) HISTORY # The gpioleds driver first appeared in OpenBSD 7.1. AUTHORS # The gpioleds driver was written by Klemens Nanni <kn@openbsd. ...
GPIOOW(4) - Device Drivers Manual # GPIOOW(4) - Device Drivers Manual NAME # gpioow - 1-Wire bus bit-banging through GPIO pin SYNOPSIS # gpioow* at gpio? offset 0 mask 0x1 gpioow* at gpio? onewire* at gpioow? DESCRIPTION # The gpioow driver allows bit-banging a 1-Wire bus as a master using one GPIO pin. The pin is used as a data signal. The GPIO pin must be able to drive an output and read an input. ...
