G760A - Prefix: 'g760a' - Datasheet: Publicly available at the GMT website - http://www.gmt.com.tw/product/datasheet/EDS-760A.pdf - -Author: Herbert Valerio Riedel <hvr@gnu.org> - -Description ------------ - -The GMT G760A Fan Speed PWM Controller is connected directly to a fan -and performs closed-loop control of the fan speed. - -The fan speed is programmed by setting the period via 'pwm1' of two -consecutive speed pulses. The period is defined in terms of clock -cycle counts of an assumed 32kHz clock source. - -Setting a period of 0 stops the fan; setting the period to 255 sets -fan to maximum speed. - -The measured fan rotation speed returned via 'fan1_input' is derived -from the measured speed pulse period by assuming again a 32kHz clock -source and a 2 pulse-per-revolution fan. - -The 'alarms' file provides access to the two alarm bits provided by -the G760A chip's status register: Bit 0 is set when the actual fan -speed differs more than 20% with respect to the programmed fan speed; -bit 1 is set when fan speed is below 1920 RPM. - -The g760a driver will not update its values more frequently than every -other second; reading them more often will do no harm, but will return -'old' values. |
