  • 03:26, 1 October 2021 73.50.18.121 talk posted a new comment on 2.8 inch Touch Screen for Pi zero (I can't reach the GPIO 18 and PWM jumper anymore because I soldered my raspberry pi already. Is there any other way to make that connection?)
  • 23:37, 30 September 2021 70.16.240.2 talk posted a new comment on CM4 to CM3 Adapter (The CM4 was not seated all the way in the converter. We also needed to use a USB hub to reduce the strain on the 3.3 V bus on our custom board but then it seemed to work.)
  • 21:57, 30 September 2021 70.16.240.2 talk posted a new comment on CM4 to CM3 Adapter (dtoverlay=dwc2,dr_mode=host was necessary to make the USB bus work on the CM4 IO Board. I am having problems with the USB bus through the converter with a VBAT of 3.3V for the converter. The USB breakout is getting 5V and was working properly with a CM3+. Any ideas on troubleshooting?)
  • 19:24, 30 September 2021 91.12.207.161 talk posted a new comment on X735 V2.5 Software (Do i get that right: You dont need both buttons? Each of them is doing much the same (Save shutdown)?)
  • 16:16, 30 September 2021 185.217.112.172 talk posted a new comment on UPS3 power off guide (Hi, I am looking for a solution to enable the pi with this UPS hat to perform a remote reboot. Currently, if I reboot I have to manually power off the ups hat and then power it on again with the ups button to get it going. Is there a way to remotely reboot without having any manual assistance to get it going again.? Thank you)

  • 20:19, 29 September 2021 91.21.57.244 talk posted a new comment on X829 (BY THE WAY: The Picture of Packing list on this side need an Update... The USB Connection ist not longer a PCB with 2 USB Plugs, it was replaced by a Cable... Thats why it works with a Raspi 3 too... But with limited speed...)
  • 20:15, 29 September 2021 91.21.57.244 talk posted a new comment on X829 (Hello @ all... I buyed the x829 and test it with a Raspberry Pi 3 - it works fine!)
  • 18:02, 29 September 2021 185.58.53.249 talk posted a new comment on P173 (To clarify: the encased Pi sits on the metal cupboard. :))
  • 17:48, 29 September 2021 Lisa talk contribs posted a new comment on CM4 to CM3 Adapter (Hi， CM4 does not have gpio44 and gpio45, so only csi0 can be used.)
  • 17:21, 29 September 2021 73.124.205.87 talk posted a new comment on CM4 to CM3 Adapter (Anonymous User #2 is GBX Technology, Giancarlo Bregante.)
  • 17:19, 29 September 2021 73.124.205.87 talk posted a new comment on CM4 to CM3 Adapter (We are using both MIPI CSI Cameras (0 and 1) on the actual CM3 design so two I2C interfaces needs to be used. We found GPIO0 and GPIO (I2C0) for Camera 0 are connected from CM4 to CM3 and Camera 0 works OK. Camera 1 is NOT working, so please let me know if GPIO44 and GPIO45 (I2C) for Camera 1 are connected/mapped from CM4 to CM3. Waiting for your answer immediately. Thanks.)
  • 16:47, 29 September 2021 109.132.74.226 talk posted a new comment on X708-Software (Dear Geekworm team, I just set up successfully the X708 board and installedt he software. However, I get the following error at step 6 (on Raspbian) when I try to read the battery level. Any idea? pi@raspberrypi:~ $ sudo python x708bat.py Traceback (most recent call last): File "x708bat.py", line 21, in <module> bus = smbus.SMBus(1) # 0 = /dev/i2c-0 (port I2C0), 1 = /dev/i2c-1 (port I2C1) IOError: [Errno 2] No such file or directory)
  • 14:50, 29 September 2021 185.58.53.249 talk posted a new comment on P173 (Just a small detail which might be interesting to others. With my model, the USB-C power plug sometimes gets direkt contact with the case. I have my Pi on a metal surface (Ikea PS1 cupboard). This sometimes resulted in the power supply not working properly (due to grounding?). To solve this, I isolated the case edges around the USB-C plug with insulating tape. (Probably putting the case on a rubber/silicon base works just as well.))
  • 12:35, 29 September 2021 Lisa talk contribs posted a new comment on X825 V2.0 (Hi，You can powered form the DC connector of the X825 board，but the X735's safe shutdown function cannot be used in this way.)

  • 12:15, 29 September 2021 Lisa talk contribs posted a new comment on HDMI TO CSI-2 (Because C779 does not support audio, please remove the audio part when you test the EDID method. （The part after mkv should be removed）.)
  • 08:59, 29 September 2021 104.6.136.133 talk posted a new comment on HDMI TO CSI-2 (I did the edid load. I have a windows 10 laptop driving the HDMI-in to the module.

  • 23:52, 28 September 2021 198.54.130.109 talk posted a new comment on DACPi (With the latest Rasbian, this does not work. I have tried both overlay lines. The original one does show errors inn syslog when audio is played. The second one does not, but, still no audio is output.)
  • 22:25, 28 September 2021 86.124.188.98 talk posted a new comment on X825 V2.0 (Basically the question is: can a bundle of X825 v2.0 + RPI 4 model B + X735 v2.5 be powered form the DC connector of the X825 board?)
  • 22:03, 28 September 2021 86.124.188.98 talk posted a new comment on X825 V2.0 (Hi. Is it possible to supply power via the DC jack of the X825 v2.0 when using RPI 4 and X735 2.5? Is there a need for a jumper cable from Vout of the X825 to the Vin of the X735?)

  • 15:13, 28 September 2021 68.96.67.227 talk posted a new comment on 2.8 inch Touch Screen for Pi zero (Hi! When laying a raspberri pi zero onto the Version B, it kind of doesn't sit and wobbles. It's perfectly ok to just solder it while it is flat and it will hold right?)
  • 15:01, 28 September 2021 Lisa talk contribs posted a new comment on HDMI TO CSI-2 (Hi，Please try to use the EDID method to test it."Use gstreamer to call camera and audio" ; and please check whether the cable is plugged in properly before.)

It does not appear to be one listed in the article above? It looks almost idenitical to Version B, but it only has 5 pins on the right (GND, PWM, AUX, VBAT, +5V). It is missing the GPIO18 pin? How do i control this board via the software using GPIO18? Thanks)
  • 18:47, 24 September 2021 88.98.85.164 talk posted a new comment on HDMI TO CSI-2 (In the features you state "HDMI Input: 720p50\720p60\1080i50\1080p25" I am trying to make the board work with a raspberry pi with a 1080i50 (interlaced) input. raspivid -t 0 shows only a cropped area of the input. I asked the question previously and the reply from Lisa was "Hi，1080p50fps input: need to specify the encoding format； Please refer to the method called with gst" I am not trying to use 1080p50fps (progressive) but 1080i50 (interlaced). I don't understand how the encoding format is...)
  • 22:38, 23 September 2021 89.133.125.46 talk posted a new comment on X-C1 Software (X-C1 kit is a raspberry pi 4 case, but scipt using wiringpi gpio. WiringPi was deprecated by its maintainer over a year ago. The 2.52 release doesn't fully work on Pi-4. IIRC there were several important functions that had breakage and the maintainer had already deprecated the project. So the X-C1 script will never work properly on the PI-4.)
