Hello, How to attach wifi/bluetooth antennae? Do I need to solder?

Hi all, I have modified the Github Python Project "rpi-backlight" to work with the Asus Tinkerboard A Python module for controlling power and brightness of the official Raspberry Pi 7" touch display. Features Change the display brightness smoothly or abrupt Set the display power on or off Toggle the display power on and off Get the current brightness Get the maximum brightness Get the display power state (on/off) Command line interface Graphical user interface Requirements A TinkerBoard including a correctly assembled 7" touch display v1.1 or higher (look on the display's circuit board to see its version) running a Linux-based OS Python 3.5+ Optional: TinkerBoard: gir1.2-gtk-3.0 for the GUI install Installation Clone this repository and install by: $ sudo apt-get install gir1.2-gtk-3.0 $ git clone http://github.com/p1r473/rpi-backlight.git $ cd rpi-backlight $ sudo python3 setup.py install Usage API Example in a Python shell: >>> from rpi_backlight import Backlight >>> >>> backlight = Backlight() >>> backlight.brightness 100 >>> backlight.brightness = 50 >>> backlight.brightness 50 >>> >>> with backlight.fade(duration=1): ... backlight.brightness = 0 ... >>> backlight.fade_duration = 0.5 >>> # subsequent `backlight.brightness = x` will fade 500ms >>> >>> backlight.power True >>> backlight.power = False >>> backlight.power False >>> NOTE: Code using set_ functions of this library has to be run as root, e.g. sudo python file.py , if the permissions for changing the backlight were not changed as described in the installation section!

Would love to see Debian 11 so we are not always behind

Hi, So we are not always one step behind in Debian, Have you thought of releasing image of Debian 11 Bullseye? We are still using Debian 10 Buster for our images

Make sure you plug the camera into the right port They swapped the camera and screen ports from Tinkerboard -> Tinkerboard 2

Was able to fix /boot/ size with GParted partition resize. Thank you.

@Frank3_Wu please consider making /boot/ partition bigger in future releases Now I am playing with GParted, trying to resize /boot/ partition so I can install wireguard

@Frank3_Wu thanks, I was able to install the kernel header successfully wget https://github.com/TinkerBoard2/kernel/releases/download/tinker_board_2-debian_10-2.0.0/linux-headers-4.4.194_4.4.194-1_arm64.deb dpkg -i linux-headers-4.4.194_4.4.194-1_arm64.deb However, it seems /boot/ doesnt have enough disk space root@Harbormaster:~# apt-get install wireguard Reading package lists...

Can't install openvpn either.

I successfully got it working For anyone else who is wondering, I got it working on SPI5 CS -> SPI5_CSN0 CLK -> SPI5_CLK DIN->SPI5_TXD

Hello, I am upgrading my 4 digit LED clock to a 8 digit MAX7219 On the 4 segment, was very simple to set up. SCL -> I2C7_SCL SDA-> I2C7_SDA However, my new board has: CLK DIN CS (It also has DOUT LODA but maybe dont need to use these) However I can not find these pins in the manual. For CLK, I have found CLKOUT, I2S0_SCLK, SPI1_CLK, SPI5_CLK but not sure I found SPI1_CSN0 which maybe is for CS? Can anyone please tell me which pins required for use with Tinkerboard? According to some tutorials, Board Pin Name Remarks RPi Pin RPi Function 1 VCC +5V Power 2 5V0 2 GND Ground 6 GND 3 DIN Data In 19 GPIO 10 (MOSI) 4 CS Chip Select 24 GPIO 8 (SPI CE0) 5 CLK Clock 23 GPIO 11 (SPI CLK) VCC 5V GND GND DIN MOSI CS CE0 CLK SCK

More progress: update-alternatives --set ip6tables /usr/sbin/ip6tables-nft Now, errors: root@linaro-alip:~# ufw enable Command may disrupt existing ssh connections.

I've made some progress: I purge ufw and iptables, then install iptables first then change to iptables-legacy. after that install ufw. ufw seems to works only on iptables-legacy. apt purge ufw iptables apt install iptables update-alternatives --set iptables /usr/sbin/iptables-legacy update-alternatives --set ip6tables /usr/sbin/ip6tables-legacy apt install ufw now: root@linaro-alip:~# ufw allow ssh ERROR: initcaps [Errno 2] modprobe: FATAL: Module ip6_tables not found in directory /lib/modules/4.4.194 ip6tables v1.8.2 (legacy): can't initialize ip6tables table `filter': Table does not exist (do you need to insmod?) Perhaps ip6tables or your kernel needs to be upgraded. Maybe ip6tables are missing in kernel? root@linaro-alip:~# sudo modprobe ip6_tables modprobe: FATAL: Module ip6_tables not found in directory /lib/modules/4.4.194 root@linaro-alip:~# ^C root@linaro-alip:~# sudo modprobe ip6tables modprobe: FATAL: Module ip6tables not found in directory /lib/modules/4.4.194

Perhaps UFW does not work on Debian 10 due to Debian 10 moving from iptables to nftables? https://serverfault.com/questions/1006981/ufw-replacement-or-workaround-for-debian-10

I am also having same issue trying to install UFW linaro@linaro-alip:/lib/modules/4.4.194$ sudo ufw enable Command may disrupt existing ssh connections.

I know the problem. On Tinkerboard 2, they swapped the place of camera and display cord. Tinkerboard 2 MIPI display port is 22-pin 4 lane, up to 1080p, but RPi's is 15-pin 2 lane. So need a convert cable or RPi's adaptor. https://uk.rs-online.com/web/p/raspberry-pi/1363742/ or https://www.waveshare.com/cm-dsi-adapter.htm

Here is document showing now Pins 3/5 -> I2C bus 6 Pins 27/28 -> I2C bus 7

I have solved this one after hours of hacking away! It seems in TinkeBoard 2/2S, the I2C bus has been changed from 1, to 6 So, in any I2C controlling code, make sure you change bus from 1 (Tinkerboard) to 6 (Tinkerboard 2) root@linaro-alip:/home/linaro/Adafruit_LEDBackpack# sudo i2cdetect -y 6 0 1 2 3 4 5 6 7 8 9 a b c d e f 00: -- -- -- -- -- -- -- -- -- -- -- -- -- 10: -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- 20: -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- 30: -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- 40: -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- 50: -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- 60: -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- 70: 70 -- -- -- -- -- -- --

So far, neither my 7" touchscreen works, nor can I detect anything on I2C...

Hi, Ive upgraded from the Tinkerboard S to the Tinkerboard 2S My I2C 7 Segment 7 Digit Display doesnt work I plugged the wires in my 2S the same way as I did for the Tinkerboard S. However, I am unable to detect any I2C pluugged in. Ive enabled all the I2C options in tinker-config. root@Harbormaster:/home/linaro/Adafruit_LEDBackpack# sudo i2cdetect -y 1 0 1 2 3 4 5 6 7 8 9 a b c d e f 00: -- -- -- -- -- -- -- -- -- -- -- -- -- 10: -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- 20: -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- 30: -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- 40: -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- 50: -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- 60: -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- 70: -- -- -- -- -- -- -- --

Hi, The Raspbian official 7" touchscreen doesnt work on the 2S like it did on the TinkerBoard and S /sys/class/backlight is empty /sys/devices/platform/ff150000.i2c/i2c-3/3-0045/tinker_mcu_bl doesnt exist like it did on TinkerBoard
