Mcp2221 Windows Driver Download [2021]
Margarete Klauer
Download this ZIP file, if you want to use the E28 module on a Windows XP, Windows 7 or Windows 8 machine. Both 32-bit and 64-bit drivers are included. Find the sub-folder to suit your system from within the ZIP file, and run the driver installation tool. This will tell you it is installing a 2200 series driver, but this also works with the 1455 chip used as the USB interface on the E28 module.
Linux and Windows 10 have native support for this USB chip, so no driver files are needed on those systems.
Download this, if you want to make your own E28 modules. Contains everything you need to build your own modules including gerbers, schematic, layout files and BOM, XP driver, GFXterm and PIC32PROG + GUI etc. Both versions 1C and 1D are included in this pack.
I have downloaded what I think are the latest drivers from MicroChip for the MCP2221 chip. This seems to be recognised by Windows 10, but when the Arduino IDE starts is terminates immediately. I tried using the debug program but that terminated immediately too. Any ideas?
Other news: I was messing about with the MCP2221 on Windows and I managed to get a poor 3 FPS refresh rate on the screen. This was using the USB to MCP2221 DLL supplied by Microchip and some driver code I cobbled together.
I forgot to say, I added in the SDL driver so I could develop mpd_oled on the desktop without needing a Rapberry Pi and a screen hooked up. Also, the window size can be specified when mpd_oled is run so I could work on layouts for different screen sizes.
The MCP2221 IC comes with drivers for Linux, Windows and OSX, plus libraries for JAVA, .NET and several utility programs. You can find all this at the Microchip page or in the list at the bottom of this page.
So I recently made an arduino clone PCB that utilizes a FT232RL chip as the bridge between my atmega328p and the USB (schematic below). However after I plug it into my PC it says "Unknown device: A request for the USB device descriptor failed" (I was hoping it'll show up as a COM port). I've installed and updated the drivers but still nothing shows up. I've also tried soldering a new chip just in case I toasted the previous one, but still it produces the same message. I am out of ideas now, please help!
So I moved on and build those kernels on the R.Pi4 (hint: make -j4 is your friend!). The module I want (the Microchip MCP2221 driver called hid-mcp2221) is in the source tree so I config'ed this up and built a kernel along with that module. I did this under 6.1.21 and 6.1.38. Neither will load into the kernel.
The goal was to drive a digital potentiometer from a PC app, preferably without any additional drivers which are always a source of attrition for users. My initial idea was to use some kind of uC which would present a HID device to the host computer and talk with the digital pot over SPI. This seemed a bit daunting at first from the software side. An alternative path would be to use a UART-SPI bridge like FT232H. This pointed me to an existing product by Adafruit which had all its functionality nicely exposed in a Python library. It was not perfect though, as it still required the user to install a generic USB driver with a third party tool. Way too fiddly and at $15 a bit expensive, too.
But this pointed me towards another product: Adafruit MCP2221A. And it was exactly what I wanted: a cheap USB bridge that presented a generic HID device interface supported by the Adafruit Blinka library. No driver installation needed. Perfect!
In retrospect, I think that avoiding writing my own drivers and instead leveraging the Adafruit libraries was the right decision. I would easily get bogged down implementing my own HID interface and with Blinka I could directly focus on the 'business logic' of pushing buttons.
