Hi all

As I have not built my universal GLCD terminal thingy yet (made the pic the wrong foot print on the board  :-[ ) I want to query my test board using i2c to a PC. You can get USB i2c boards which I will need but I also need some software to run a script to request data from my test board. Then convert that into something I can read.

Eg Mchip float format (IEEE 754)

Does anybody know of any software to do the job?

Thanks

Tim

I read there's an option to turn the I2C from a Pickit3. Even USART of it, but nothing I could find to be able to use it.

Few years ago on developing some code for an AS7261 bought a kit for it and there was included a FTDI USB cable type C232HM , which can do i2C.

The software used for testing i2C used was this CLI from : MPSSE_TOOLS
GL & 73

I know the Pickit Serial can script commands but don't think the supplied software can reprocess the replies.  They do have a DLL, so you could write a program in VB, examples in the manual here

Hi Tim,
Is this anything like the project you're wanting to build?

I just stumbled on it and wondered if it may be of interest.

Cheers,

Nice. The only problem with that might be the lack of VGA on modern monitors.
