IICHID(4) Kernel Interfaces Manual IICHID(4) NAME iichid -- I2C HID transport driver SYNOPSIS To compile this driver into the kernel, place the following lines in your kernel configuration file: device iichid Alternatively, to load the driver as a module at boot time, place the following line in loader.conf(5): iichid_load="YES" DESCRIPTION The iichid driver provides a interface to I2C Human Interface Devices (HIDs). SYSCTL VARIABLES Next parameters are available as sysctl(8) variables. Debug parameter is available as loader(8) tunable as well. dev.iichid.*.sampling_rate_fast Active sampling rate in num/second (for sampling mode). dev.iichid.*.sampling_rate_slow Idle sampling rate in num/second (for sampling mode). dev.iichid.*.sampling_hysteresis Number of missing samples before enabling of slow mode (for sam- pling mode). hw.iichid.debug Debug output level, where 0 is debugging disabled and larger values increase debug message verbosity. Default is 0. SEE ALSO ig4(4) BUGS The iichid does not support GPIO interrupts yet. In that case iichid en- ables sampling mode with periodic polling of hardware by driver means. See dev.iichid.*.sampling_* sysctl(8) variables for tuning of sampling parame- ters. HISTORY The iichid driver first appeared in FreeBSD 13.0. AUTHORS The iichid driver was written by Marc Priggemeyer <marc.prigge- meyer@gmail.com> and Vladimir Kondratyev <wulf@FreeBSD.org>.
