Re: [Flashforth-devel] more fun with PIC18F46K22-s...

I am not sure I fully understand what you are doing, but...
I hope you are  running at full clock speed.

To get more capacity I would use HW timers for the ADC and PWM.
That saves many cycles.

Remember that your user interrupt routine is checked
at every interrupt. Except in the latest FlashForths.
There the system tick will not check the user interrupt.

You can put the UART2 stuff in two background tasks.
Something like this.
I assume RX2 and TX2 calls PAUSE if they would block.

0 30 30 0 task: rx2.task
: rx2.loop
   init.rx2
   begin
     rx2
     processchar
   again ;

0 30 30 0 task: tx2.task
: tx2.loop
   init.tx2
   begin
     get.char.from.tx2.memory.queue
     tx2
   again
;

: main
   init.uart2
   ['] rx2.loop rx2.task tinit
   rx2.task run
   ['] tx2.loop tx2.task tinit
   tx2.task run
   begin
    bla.bla
    pause
    put.char.to.tx2.memory.queue
   again
;
