Control/program C85xx with MCU

Mathieu Hebbrecht

Other Parts Discussed in Thread: CC2511

Hi everyone,

I have a few question regarding the C85xx PurePath 2.4 GHz range. In the product brochure and datasheet there is mentioned that these chips can be controlled by a MCU. However I'm not able to find any details. Why is that?
I recently bought a Headset dev kit to get to know the C8531, I am a fan. And I want to implement this into my concept which contains a small MCU with usb interface. In order to make a transparent and easy to use platform (for possible mass production) I would like to be able to totally control the C85xx by my MCU. So I only need to flash the boot loader of my MCU. So once connected to a USB port everything can be controlled by the computer.

In short I want to flash the C8531 using only my MCU.
I suppose SPI is used to do so, but is there information about this way of working? Would I be able to flash the output file of the PurePath configuration into C85xx like the CC2511 debugger does?

Kind regard,

Mathieu H.

Since no one answered my question(s). I continued the search. Luckily I found this document:

Below in appendix B you find some info on the SPI slave interface. There they refer to functions, unfortunately I was not able to find these function in C or any other program language. So It is gonna take a while to develop them.

Maybe someone did this already, and is willing to share the source code with me?

Now this is an answer. Library is include. Awesome! Thanks Johan!
Still one question. In the doc folder there is a help file included. I can see all the indexes, but no content.
I'm using the default windows help to open the file. But I'm not able to see any text nor description. Is this normal? In the source code there is some explanation, but it would be helpful to also have the help file working.
Any Idea's?

Hi,

A did a quick search, and it seems that .chm files are sometimes not supported out of the box on Win 7, Vista and 8. But you should be able to download a plugin to be able to open this file correctly.

Hi Johan

Thanks for your fast feedback. Windows seems to have issue's with .chm files on network locations. So copying the file to a local directory did the trick. With the information you gave me I'm able to continue.
