Yes

@@TECHEONICS sir if I have a problem regarding this can I connect with you

Which operating system you are using is this is a bullseye legacy?

I followed your process but it won't work for me can you please help me I am trying this upto 5 to 6 days

1. VNC Server Configuration: * Keyboard Layout: Ensure that the keyboard layout in your VNC server settings matches your physical keyboard. Incorrect layout settings can prevent proper key recognition. * Keyboard Mapping: Double-check if there are any custom keyboard mappings or shortcuts that might be interfering with typing. If you've recently modified these settings, try reverting them to default. 2. Raspberry Pi Configuration: * Keyboard Layout: Verify that the keyboard layout is correctly set in the Raspberry Pi's configuration. You can access this through the "raspi-config" utility. * USB Hub Compatibility: If you're using a USB hub, ensure it's compatible with the Raspberry Pi and that it's providing enough power to the keyboard. Some USB hubs might have power limitations. 3. Keyboard Issues: *Physical Damage: Check for any physical damage to the keyboard, such as broken keys or loose connections. * Driver Issues: If you've installed any custom drivers for the keyboard, ensure they're compatible and functioning correctly. Update Raspberry Pi Software: *Ensure that your Raspberry Pi's software is up to date. Outdated software can sometimes cause compatibility issues. Check for VNC Server Updates: If you're using a third-party VNC server, check for updates and install them if available. If these steps don't resolve the issue, please provide more details about your setup, including the VNC server you're using, any custom configurations, and any error messages you might be encountering.

@TECHEONICS sure I will update and let you know Thank you for the reply

The issues you're experiencing with your Raspberry Pi are likely due to a combination of factors. Here's a breakdown and potential solutions: 1. Inconsistent Flashing: * Corrupt SD Card: The SD card might be corrupted, leading to inconsistent flashing. Try formatting the SD card and flashing the image again. * SD Card Quality: Ensure you're using a high-quality SD card specifically designed for embedded systems. Poor-quality cards can be unreliable. * Power Issues: Inadequate power supply can cause flashing inconsistencies. Make sure your power adapter is providing sufficient power. 2. Unreadable Passwords After Reset: * Imager Configuration: Check the imager settings to ensure you're using the correct password format. Some imagers might require specific password encoding. * Imager Version: Outdated imager versions might have compatibility issues. Try using the latest version. 3. Advanced IP Scanner Not Showing the Pi: * Network Configuration: Verify that the Raspberry Pi is correctly configured to connect to your network. Check the IP address and subnet mask in the Raspberry Pi's configuration. * Firewall Settings: Ensure that your router's firewall isn't blocking the Raspberry Pi's network traffic. Troubleshooting Steps: * Format the SD Card: Use a reliable SD card formatting tool to format the card. * Flash the Image Again: Use a fresh Raspberry Pi OS image and flash it to the formatted SD card. * Check Power Supply: Ensure you're using a suitable power adapter for the Raspberry Pi. * Verify Network Configuration: Double-check the network settings on the Raspberry Pi and your router. * Disable Firewall Temporarily: If you're using a firewall, temporarily disable it to see if it's blocking the Raspberry Pi. * Try a Different SD Card: If the issue persists, try using a different SD card. * Update Imager: If you're using an older version of the imager, update to the latest version..

​@@TECHEONICS Hi, thanks for the reply. I have formatted the SD card in fat32 format. I am using a 128GB one, which I bought just a few days ago. For the imager, when I input the passwords, it seems fine, but when I reopen the settings, the password textbox becomes encoded with hash. I tried with different versions of the imager from 1.8.5 to 1.7, but the problem still exists. I suspect that it can't connect to the wifi because of this changed password problem. I try to connect the raspberry pi to a monitor through HDMI with a new strong cable, and it does show some lines of processing code on the screen, but every time it is about to reach the line for login, the HDMI disconnects, and I have to replug the power source to allow it to boot again, making it an endless loop lol.

Yes

robu.in

Yes

Is this after first boot or after installing the driver ?

​ @TECHEONICS yes, after installing the driver, when call a first boot.

@@maicoul CONNECT HDMI AND REINSTALL THE DRIVERS

I am also facing same problem

Yes

Thank you so much for your kind words and for appreciating the effort I put into creating this video! I’m thrilled to hear that it has been helpful to WaveShare customers in setting up their 3.5-inch screens. I’m genuinely excited about the possibility of collaborating with WaveShare on future projects. In fact, I’ve recently purchased and am working on a video series covering several of your displays, including the 3.5-inch, 5-inch, 7-inch, and 10-inch models. Additionally, I’ve acquired multiple other WaveShare products, which I find very intriguing. I plan to share videos and articles about these within the next six months. I’d love to explore further opportunities to work together, whether it’s through sponsored content, product reviews, or any other form of collaboration. Please feel free to reach out to me directly via my email = [email protected] Thank you once again for your support, and I look forward to potentially working together in the near future! Best regards, Gaurav www.techeonics.com [email protected]

SD card is not the problem try plug in a display with the Raspberry Pi and see if it's put up or not if you don't have the display available right now just burn the OS on 16 or 32GB SD card do set up the Wi-Fi from the pi imager settings and do mention country code as well in the Wi-Fi setting

Yes

@@TECHEONICS make a video on that brother :) rpi 5 is the latest one

@@TECHEONICS i try using rpi 5 but it only turned dark and work as mouse pad only

I suggest, using the raspian os image from lcdwiki, you just need to flash it. and it works on pi5.

On it

which vnc should i download windows or raspberripi

Yes

Using a 10k thermistor instead of a 4.7k thermistor in acircuit will likely cause incorrect temperature readings and require recalibration of the circuit. Use the Potentiometer to set the value after calibration

In the video I use 104 potentiometer which is 100k. You can go with 100k or 500k potentiometer both will work

Did you add the i2c Lcd library?

47 ohm Check out post for more info - techeonics.com/fan-controller-with-ua741-ic/

What's the issue?

It could be either a software or hardware issue. 1. Check power supply. 2. Ensure microSD card is inserted properly with a valid OS image. 3. Verify all connections. 4. Test with different power supply and microSD card. 5. Monitor boot process via HDMI.

​@@TECHEONICS can I use 64gb microSD card in 3b+ Rpi??

@@redskull1890 Yeah, it doesn't matter about the size, I also use a 64gb microsd in my 3b, and 4b
