Frequently Asked Questions
This section contains general information and things that are not covered in the other sections.
Q When I load a program on SD Card instead of getting the ok prompt I get '>'
All files must have an extra line at the end of the program otherwise the end of file will be detected too early and the last line, which is normally 'endf' will not be loaded. The solution is to add an extra line at the end of the file.
Q What is the size of the board and how is it powered?
The PCB size is 85x35mm and the overall size is 90x38x20mm including sockets that stick out. The power is obtained form the USB so no power supply is required. On a stand alone application without the USB the power required is DC from 5V to 10V, on board regulators take care of the actual voltages to the input is flexible.
Q What documentation comes with the BV513?
A copy of this web site on CD-ROM, taken at the time the CD-ROM was made.
Q How fast does the system run with interpreted BASIC?
See the the internals page in PIC32-Basic for some timings
Q PIC32-Basic does not work anymore, how do I reload it
Full instructions for reloading PIC32-Basic are in the PIC32-Basic section here. You will need the PIC32-Basic hex or binary file from the CD-ROM.
Q How do you make the BV513 run at start up
This is actually explained in the PC32-Basic internals topic. The start up sequence is as follows. 1) A search is made for an SD Card in either channel A or B, if there is a card in A then that is chosen as default and if B then that one. 2) System constants are searched for in RAM and Flash and if found set to the new values. 3) A search for a function called 'auto' is carried out in RAM then Flash and then the default SD Card. If it is found the function is executed.
In answer to the question, create a function called 'auto' and save it to Flash or the SD Card.
