Hi I am having trouble testing out my EB055 USB block as I cannot find the correct driver for it.
I am using Windows 7 and tried searching the Matrix mini disc and the web for the correct driver but it cannot be found.
Can anyone help me with this? Thanks.

Hello,
The EB055 is designed for use with a USB enabled PIC device. There is no driver file as such as the driver must be tailored to your application. The Flowcode USB components generate driver files so these are probably what you are looking for.
There is an article which details a lot of this so this is a good starting point.

Let me know how you get on.

I haven't been using flowcode yet just the example hex program from the site loaded straight onto a 18F4455 with PPPv3.
I will read the article and try again. Thanks for the help.

Hello,
Ok sorry, for the pre-compiled example the driver files are inside the Flowcode example zip file which is available on the E-blocks datasheets page.

Hi Benj,
I've done a USB flowcode program and I am generating the USB driver file which I got from the EB055 test.zip folder.
When I connect my USB E-Block it says the device has malfunctioned and Windows does not recognise it.
I went into the device properties to to update the driver but it just keeps telling me the best driver is already installed for this device.
Any ideas on how I could change it?

I have also tried this on my computer in college. I got the same message and went in to update the driver.
I pointed it to the usb_driver.inf file and it just says this specific location does not contain information about your device.
I have no idea what i'm doing wrong

Hello,
Device has malfunctioned and Windows does not recognise it
This is the case when your Flowcode chip configuration settings are incorrect.
Clock speed in the project options should be set to 48000000.
Configuration settings should match those shown here:

Except the highlighted field which should be changed to suit the crystal speed on your hardware.

Thanks Ben I changed the clock speed and it allowed me to install the device.
I also got the chip talking to hyperterminal so I am very happy with that.
Thanks again for all your help. Much appreciated.
Sean.
