New page

''/opt/vc/bin/vcgencmd commands''

Shows a list of possible (needs verification) commands.

Verified commands:

vcgencmd measure_clock <clock>

Shows clock frequency, clock can be one of arm, core, h264, isp, v3d, uart, pwm, emmc, pixel, vec, hdmi, dpi.

vcgencmd measure_temp

displays rpi temperature

vcgencmd codec_enabled <codec>

Shows if the specified codec is enabled, codec can be one of H264 MPG2 WVC1

Parameters and function of other commands are not known.
