  • 03:45, 8 August 2020 35.134.21.24 talk posted a new comment on X728-Software (Where are the additional files. The git only has the setup script. But the script calls for the files, which are absent. Any help?)
  • 23:56, 6 August 2020 78.34.229.145 talk posted a new comment on X735 (The x735 is using GPIO18 for PWR_MGMT, but I want to use a ir sensor like tsop 3xx. With the sensor connected every time the x735 is shutting down. how could I solve that?)
  • 22:48, 6 August 2020 173.165.48.1 talk posted a new comment on LVDS To HDMI Adapter Board (Can this run LVDS in at 800x600 at 100Hz?)
  • 20:05, 6 August 2020 145.128.163.81 talk posted a new comment on X825 (Can the X750 be used to power the X825?)
  • 23:24, 5 August 2020 77.8.144.68 talk posted a new comment on X400 V3.0 (Important information missing as well: The power switch simply cut the power to the whole system. there is no proper shutdown of the raspberry, it is like removing the plug. To turn off the raspberry in a clean way when pressing the button, I made a small circuitry with a relay that latches the poser supply and sends a power interrupt to the pi to turn it off when the button is pressed. The relay opens the power to the board once the rpi has shut. There are some out-of-the-box shields on inte...)
  • 23:14, 5 August 2020 77.8.144.68 talk posted a new comment on X400 V3.0 (There is an error on the power switch connector. Pin 3 is not GND but the voltage of the power supply. (for example in my case I supply 12Vdc -> the pin is at 12Vdc). That Voltage is also the one supplied on the Speaker and power terminal (it is always supplied, also when the system is off by power switch))

  • 23:09, 5 August 2020 77.8.144.68 talk posted a new comment on X400 V3.0 (the IR should be accessible on GPIO26. Then you can look up on other forums on how to use the IR on a RPi, there are several tutorials.)

  • 18:52, 27 July 2020 Cindy talk contribs posted a new comment on X728-hardware (Hello sir, When use the X728 with X825 board, please power from X725, do not power from X825 or Raspberry Pi 4.)
  • 04:17, 27 July 2020 Pmsr talk contribs posted a new comment on X728-Software (Managed to get my new x728 going. Solid hardware. But am getting the following output from x728bat.py. What does the Voltage at 4.21V mean? It's far from the 3.7V nominal from the batteries, and from the 5V required for the Raspberry Pi. And 103% for the capacity? The script expects 100 to print "Battery FULL", so there is a fix in need here. ****************** Voltage: 4.21V Battery: 103% ******************)

  • 06:16, 23 July 2020 Abarrow talk contribs posted a new comment on X710 (Great board. One little convenience is that if you have something in the same enclosure that needs to share the input voltage (in my case, it's a 12V USB hub) you can use the other input voltage connector - it's parallel with the power socket, and is NOT switched.)

  • 14:01, 17 July 2020 JdeFalconr talk contribs posted a new comment on 2.8 inch Touch Screen for Pi zero (Hello, I've just connected this screen to my Pi Zero W but I get no output. The Pi boots normally but the screen's backlight just flickers intermittently and nothing displays on the screen. I went through the online setup script and rebooted afterwards, also doing an apt-get update too for good measure.)

  • 20:36, 8 July 2020 91.84.191.182 talk posted a new comment on X735 (I have the x735 v2.1 working on a Pi 4B running Buster. However it doesn’t work when I plug a HiFiBerry DAC + Pro due to conflicts with GPIO. The Pi system just halts after the DAC kicks in from the script /etc/x730pwr.sh HiFiBerry states the GPIO18 the sound interface in hardwired on the Pi so it can’t be mapped onto another pin. GPIO18 is only used for software shut down $ x730off that I’m not going to use Reference script /usr/local/bin/x730shutdown.sh I have re mapped the GPIO4 and 17...)

  • 05:59, 7 July 2020 Bartoszkobak talk contribs posted a new comment on T200 (Thank you for the code. When i run the code the battery voltage slowly drops from 4.22v to 4.17 whilst in a loop but power is supplied via the dc jack (5V 4A). When i unplug and plug in the power again the voltage goes back to 4.22V. Could anybody possible assist? Thank you)
