Hi all, I am working with the TI TUSB3200, trying to modify their example code for our own USB device. USB requires many tables which start with a length byte. I would like to use the sizeof operator to calculate this for me, as shown here:
byte code rictest[] = { sizeof(rictest), 1, 2 };
warning C198: sizeof returns 0
A very neat trick Niels, I'll remember that in future. It would probably be possible to base a solution on this trick. I now find that externally linked modules needed to know the length also, currently it is defined in a .H file. I could modify the external modules to read the length from the array, but I might just stick with writing a utility to auto-genaerate the .c and .h files, with the length calculated automatically and inserted into the source. This will make the source easier to read (& understand) when the project is complete.
