Two webcams were connected in the tinker edge. `cv2.open()` works well for two webcams, but only one webcam can be read. How do I `cv2.read()` two webcams at the same time?

Hello everyone. I need to measure temperature with a DHT11 using Python and I can't get it. I have a tinker board R2.0 and the latest version of Tinker OS. I have tried with two Adafruit libraries: Adafruit_DHT and adafruit-circuitpython-dht. With the first package, which I think is the simplest and has worked on my raspberry, I get the following error: raise RuntimeError('Error accessing GPIO. Make sure program is run as root with sudo!') RuntimeError: Error accessing GPIO. Make sure program is run as root with sudo! I have tried to run the program from the terminal as root with sudo but the same problem still appears. I have tried to measure with a DS18B20, but the libraries I find are not compatible with the tinker board either. I also tried with a MCP9600, which works with I2C, but it doesn't work either. When I search for the address with i2cdetect -y 1 it only recognizes the MCP the first time. If I use i2cdetect -y 1 again, it does not appear anymore. I have to disconnect and reconnect the device for i2cdetect -y 1 to detect it. I don't care which of the three methods to use to measure temperature. I would like to know if anyone has managed to use any of these three methods. I have tried with a Raspberry Pi 3B the same libraries and had no problems. I'm a bit desperate with the tinker board 😖 Thanks a lot

Hi, I am using a Tinker Board Edge R, but the situation should happen on general Tinker Board products, I believe. When I installed VLC, when I play a mp4 file, I will receive the following errors: libGL error: unable to load driver: rockchip_dri.so libGL error: driver pointer missing libGL error: failed to load driver: rockchip libGL error: unable to load driver: rockchip_dri.so libGL error: driver pointer missing libGL error: failed to load driver: rockchip and the video is very laggy, obviously the hardware acceleration was not applied. Not sure if this problem applies to all Rockchip SBC. Thanks Arnold

Hi. I was trying out a project for my Tinker board and because I ran out of disk space, I decided to remove Python2 from the Tinker board. After removing Python, I noticed that I had no Wi-Fi connection to the Internet, but I do have connection via ethernet cable. After noticing all of this, I also noticed that the wlan0 device is no longer found when running the nmcli command, but when I run the lspci command, the system detects the Network controller: Qualcomm Atheros QCA6174 802.11ac Wireless Network Adapter. Having said all the information I know and being new to Linux, I was wondering if there is a solution to this problem. Thanks in advance!!!
