Simple Maths Going Wrong

[jellis00]

DT,

I used StampPlot from Selmaware for a PID motor control demonstration last year, thoughts on it ~ may be of some interest in your development?

1. Fantastic that I could produce a PC interface without learning Visual Basic.

2. I think it was free, or I paid a very small amount of $ for the improved graphic design function.

3. The complexity of the commands was OK once you had an example to modify ~ working with the User Guide alone was, in some cases, very difficult.

4. The supplied controls, whilst functionally good, were visually poor ~ I imagined they were modelled on instruments in a Soviet 1950 power station.

5. I would have been prepared to pay more for a better product that had the benefit of lots of polishing.

6. However, excellent value for the very low cost ~ a labour of love for the developer.

Bill, I also am trying to get an application going without having to use VB6. I need to interface a laptop computer to an 18F4550 based microcontroller via USB to read the data stored by the 18F4550 in its EEPROM over a 31 day period [93 bytes = 31 daily measurements x (date value, Data_LSB, Data_MSB) ] . I need the data to be inserted on the PC side into an Excel spreadsheet for plotting and analysis purposes by the user. It appears that StampPlot might be a candidate to do this, but it appears it really only works with BasicStamp and RS232 or serial interfaces and not USB. As a user of StampPlot can you advise me if I can adapt it to use for USB and PICBASICPro without a huge learning curve? My controller is done and my project has a short fuse so can't spend a lot of learning time to get the PC side and USB interface going Would really appreciate your advice!~
