Talk:Fex Guide

I'm seeing some tags that aren't mentioned in the [Fex Guide] - sb_pwm[n] and pwm_gpio. Where can we find documentation on these tags?

Seen in pcdunio.fex

[sb_pwm0]

pwm_gpio = port:PH06<1>

[sb_pwm1]

pwm_gpio = port:PB02<2>

[sb_pwm2]

pwm_gpio = port:PI03<2>

[sb_pwm3]

pwm_gpio = port:PH05<1>

[sb_pwm4]

pwm_gpio = port:PI10<1>

[sb_pwm5]

pwm_gpio = port:PI12<1>

Some additional useful parametres, not mentioned in main
[clock]

Used after [target] If I understand correctly, it is a way to set up the clock of GPU. Since what I saw in fex file can relate only to video. After setting the clock, can set the divider in [mali_para] to 1. Now I wonder if the whole section doesthe same as parametres pll4_freq and pll6_freq in [target] section

usage example [clock] pll3 = 297 pll4 = 300 pll6 = 600 pll7 = 297 pll8 = 336

... [mali_para] mali_used = 1 mali_clkdiv = 1 _________________________________________________________________________________

[ctp_list_para]

Set up a list of used ctp devices. Not sure if it replaces insmod in boot.img, but may have a try. Makes adding ctp more easy. Heres the example [ctp_list_para] ctp_det_used = 1 gslX680 = 0 ft5x_ts = 0 gt82x = 0 gt9xx_ts = 0 gt811 = 0 aw5306_ts = 1 zet622x = 1

[disp_init]

Additional switches for disp_init lcd _backlight lcd _bright lcd _contrast lcd _saturation lcd _hue 

example: [disp_init] ... lcd0_backlight = 197 lcd1_backlight = 197 lcd0_bright = 50 lcd0_contrast = 50 lcd0_saturation = 57 lcd0_hue = 50 lcd1_bright = 50 lcd1_contrast = 50 lcd1_saturation = 57 lcd1_hue = 50

[camera_list_para]

Seems like the same as ctp_list_para, but sets up camera drivers list to use. Also not sure that can replace insmod.

camera_list_para_used = 1 sp0718 = 1 sp2518 = 1 ov7670 = 0 gc0308 = 1 gt2005 = 0 hi704 = 0 sp0838 = 1 mt9m112 = 0 mt9m113 = 0 gc2035 = 0 ov2655 = 0 hi253 = 0 gc0307 = 0 mt9d112 = 0 ov5640 = 0 gc2015 = 0 ov2643 = 0 gc0329 = 0 gc0309 = 0 tvp5150 = 0 s5k4ec = 0 ov5650_mv9335 = 0 siv121d = 0 nt99252 = 1

Something really interesting in usage of [gsensor_para]. It can also use the parametr like [gsensor_list_para]. But in fex I saw it was used the way like in example - without settings in gsensor itself.

[gsensor_para] gsensor_used = 1 gsensor_twi_id = 3 gsensor_int1 = gsensor_int2 =

[gsensor_list_para] gsensor_det_used = 1 mma865x = 0 bma250 = 0 mma8452 = 0 mma7660 = 1 afa750 = 0 lis3de_acc = 0 lis3dh_acc = 0 kxtik = 0 dmard10 = 0 dmard06 = 0 mxc622x = 0 fxos8700 = 0 lsm303d = 0 stk831x = 1
