Hello,

I am trying to create a profile for google chormebooks. However I am running into a wall. The EC code shows hexadecimals not integer. Even after I put them It did not seem to work. Am I doing something wrong.

This is the Fan controller from the bios.
https://chromium.googlesource.com/chromiumos/platform/ec/+/factory-1235.B/host_interface/ec_command.h

/* Thermal and fan */

| EC_COMMAND_THERMAL_CMD = 0x20,
| EC_COMMAND_THERMAL_CMD_MASK = 0xf0,
| EC_COMMAND_THERMAL_GET_CURRENT_FAN_RPM = 0x21,
| EC_COMMAND_THERMAL_GET_TARGET_FAN_RPM = 0x22,
| EC_COMMAND_THERMAL_SET_TARGET_FAN_RPM = 0x23,
| EC_COMMAND_THERMAL_READ_SENSOR = 0x24,
| EC_COMMAND_THERMAL_SET_ALARM_RANGE = 0x25,
| /* TODO: PECI? */

This was my configuration

`<FanDisplayName>CPU fan</FanDisplayName>
<WriteRegister>47</WriteRegister>
<ReadRegister>46</ReadRegister>
<MinSpeedValue>88</MinSpeedValue>
<MaxSpeedValue>48</MaxSpeedValue>
<IndependentReadMinMaxValues>false</IndependentReadMinMaxValues>
<MinSpeedValueRead>0</MinSpeedValueRead>
<MaxSpeedValueRead>0</MaxSpeedValueRead>
<ResetRequired>true</ResetRequired>
<FanSpeedResetValue>255</FanSpeedResetValue>`

Use google searches like "0x24 to decimal" and "191 to hex":

Like this - it is handy:
