Kauj Ruam 6: Yam Ua

Kuv tsis tuaj yeem nruab nws vim nws xav tau Python 3.5.3 lossis tom qab. TAB SIS kuv muaj version 3.6.x thiab nws tsis kam mus ntxiv. coj txawv txawv heev. puas muaj leej twg thov pab kuv nrog qhov no?

2. nruab hdmi CEC ntawm C2.

ntaus hauv lub davhlau ya nyob twg: sudo apt-tau nruab cec-utils

tom qab CEC tau teeb tsa, txheeb xyuas CEC ua haujlwm, hom: echo scan | cec -neeg -s -d 1

nws yuav tsum pib teev hom TV twg C2 txuas nrog.

3. pab kom HDMI CEC hauv HA. yog li thaum pom cov lus tsa suab, C2 yuav tshaj tawm CEC raws tu qauv kom qhib TV. thaum lub suab tsis pom, C2 tig TV tawm ntawm CEC.

Kauj ruam 7: Troubleshooting

1. ubuntu rebooting nws tus kheej. tsis muaj zog txaus. tsis txhob siv lub zog C2 ntawm lub chaw nres nkoj micro usb. fais fab C2 chav ntawm lub thoob ntsaws uas ameridroid.com muag rau ib ncig $ 7. Kuv siv sijhawm tsawg kawg 20 teev los daws qhov no.

2. TV qhia qhov screen dawb paug lossis tsis muaj teeb liab. sim lwm HDMI cable. sim lwm lub hwj chim txuas rau C2.

3. TV qhia tau tias yog teeb liab. koj puas tua ubuntu pw tsaug zog lossis hom tshuaj ntsuam?
