Though most examples are for Visual Basic.NET, it is relatively easy to adapt them for Visual C++.NET and other high programming languages.Įxamples with source codes and photos are included! 5. There are many ongoing projects on the internet, but only PC USB Projects website enables you to easily exploit the full functionality of your PIC18 and PIC32 microcontrollers from Microsoft Visual Studio.NET environment. PC USB Projects website is committed to provide free PIC18 and PIC32 firmware as well as the best free programming interface for your application to make your dreams come true.

I suppose it's the radio equivalent of the BMW/Mercedes drivers who overtake everyone, then pull over at the very last second to exit a motorway as an inconvenience to everyone else and they get away with it.ABOUT PC USB PROJECTS HOT TOPICS 0. Like one person commented no one knows you peed in the pool! So like 446Mhz and other "CB" radios that are supposedly type-approved blah, blah, you will always get someone "blasting" their signals illegally and get away with it. Unfortunately it meant having to change the WiFi board for a whitelisted European version. So, if you buy a MacBook in the USA like i did then wonder why it wouldn't see my Access Point (on channel 13) here's the reason (above). In the USA they have 11 WiFi channels on 2.4Ghz where in Japan they had up to 14. So lets set the record straight: 2.4Ghz WiFi band is ISM and that all secondary users must accept interference from other users. Also it is open to interpretation as ITU GUIDELINES can differ "In-Country". Who gives a flying f**k about FCC rules or CE rules for that matter? UK (where the PI originates from) has different certification methods. The Raspberry Pi Zero W is mounted between the power supply/controller PCB and the touch screen so the onboard antenna would be shielded by both boards. The photo below shows the new modified Pi attached to the Barcode scanner project we are working on. Please note this will invalidate the FCC certification. Testing the Raspberry Pi Zero W with the external antenna Testing the Raspberry Pi Zero W with the built-in antenna Most networks showed an improvement with the new external antenna and our home network had a much greater signal strength. The following table shows a list of networks found and their signal strength and quality readings. To test the new external antenna compared to the built-in PCB antenna we used the following command to scan for available Wi-Fi networks. The connector fitted to the Raspberry Pi Zero W The link rotated and the new U.FL connector was fitted. ![]() We carefully removed and rotated the resistor to the U.FL link pad and then soldered the new U.FL connector to the board. On the Raspberry Pi PCB, there is a component which appears to be a zero ohm resistor (0201 size 0.6mm x 0.3mm) which links to the PCB antenna or can be turned 45 degrees to link to the U.FL connector bypassing the internal antenna. We already had a suitable Wi-Fi antenna and so we ordered the U.FL connector and a short coaxial cable assembly from Farnell. Upon receiving the new board we noticed that the Raspberry Pi foundation has left a space and jumper pad for a U.FL RF connector to use with an external antenna. The new Raspberry Pi Zero W has built-in Wi-Fi and so we thought this would be better than the USB dongle which we are using with the barcode scanner. There is a blog post for the Raspberry Pi Zero 2 W which was released in 2021 With the release of the new Raspberry Pi Zero earlier this week we ordered one from The Pi Hut to use with our expansion boards (they all work without any problems) and one from Pimoroni to use with our barcode scanner project.
