giseleznev posted a topic in SoftwareHi, team, I want to connect tinker board 2 with dac PCM5102PW and also adc PCM1804DBR using i2s and i2c Is i2s and i2c interface supported currently? Can i use alsa over i2s out of the box? Or should I install any overlays? Thanks!
Impossible to read temperature withGPIOHello 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
