Swordfish

USB Modules released...

Just email me the device name (and if you need PLL) and I will see if I have them or can build them for you.

Swordfish USB modules are now available. The USB HID module enables you to send and receive structured data from microcontroller to PC via a USB connection. The USB CDC module acts like a RS232 Virtual COM Port (VCP). Registered Swordfish users should just select VIEW...ONLINE UPDATES from the IDE t...

Yes, the PIC has only two possible interrupt levels (high and low). If two events share the same level, you need to differentiate in some way.

#option GLCD_CS1 = PORTD.7

GLCD_CS1 . GLCD_CS1@
PORT PIN

Sorry, I misunderstood your question - I thought you were referring to names generated by the compiler. As far as swordfish is concerned you can call an interrupt anything you like...It's just a name given to either a low or high interrupt source. What you do inside, and what interrupts are actually...

Your should not assume anything about the name of a sub, function or interrupt. If the compiler changes its underlying code generation (which it might) it would break any code based on assumptions about labeling.

Well, you certainly do pick up a few things along the way although I have to admit that the main 'USBSystem' module is a port from the microchip C libraries. I've pretty much left the code as is, so this should allow people who want to dig really deep into USB to reference much of the microchip docu...

As soon as I have something ready I will post an announcement on the forum. The code is rather complex and I won't be releasing it until I'm sure it all works OK. It's all written in Swordfish BASIC, no ASM... I am implementing both USB HID and CDC. The HID module offers transfer rates of 64KBytes s...

Forces all params, locals and intermediate working registers to be located in access ram. Its not documented because it needs to be used with extreme care.

That's what the example code I posted does...

function MyUserSubroutine( SomeParam as byte) as byte result = SomeParam end function sub MyCallingSubroutine(myParam as byte) asm ; set bit Value... movf DataPort, W andwf MakeLow, W btfsc STATUS, C iorwf MakeHigh, W movwf DataPort end asm Value = MyUserSubroutine(myParam) asm decfsz Index, F bra ...

I cannot give you a date at the moment - the biggest demand from users is modules - so that's what I am currently looking at.

The IDE does not have an ICD at the moment but it is likely to be based around the COFF file format, if you want to get an idea of what will most likely be used...
