[Flashforth-devel] interrupt on input change

[Bob E. <bob...@ti...>]

Has anyone implemented a shaft encoder by 'interrupt on change of input' 
with Flashforth? It needs a mod to ff18_usb.asm, am I right?

I've been writing 2x16 char LCD driver words on a 18F4450 and wanted to 
add a 'tuning knob' before having a go at a SI570 programmable RF signal 
generator via the i2c interface. Flashforth very easy to use - I've been 
a hobbyist 'forther' for many years.

I could poll the shaft encoder inputs, possibly from a timed interrupt, 
but that's not as efficient as the above.
