Re: 16f18877 internal Zero Cross Detector
The pin declared in properties is for output - I'd connected this (RD1) to a logic analyser - it was easier than wiring up a UART convertor... The zero crossing interrupts on RA0 - I think this is fixed on the 18877 - but other PICs might be able to remap to other pins.. This is set up (analog / inp...

Re: Lookup table in simulation
Would it be easier to treat CR/newline as whitespace - and require a comma after all but the last entry.
Blank lines are quite nice as a divider? - Although comments could be used:
// This line intentionally left blank
Sort of thing....

Lookup table in simulation
More of a gotcha than a bug - defining data in LUT I would typically have: 0x1,0x2,0x3,0x4,0x5, 0x6,0x7,0x8,0x9,0xA The newline throws simulation out - although the data works correctly when compiled to hardware... I rather like being able to add newlines (and comments) to the LUT data. Long data do...

Re: Internet radio
That would be an interesting project - there are several 'areas' that need to be addressed - connect to 'stream', audio output (via I2S), display / selection of station etc.
Flowcode has components for these areas - can you share your source - and we can look at how it could be Flowcoded

Re: Update project to F10
Whoosh - not just faster - better broadband too!!!
Looking at Skylink - and 100Mb/s is described as suitable for 'light browsing' (for the heavy stuff upgrade to 200Mb/s)
Wonder what BT's offering is good for???

Just re-downloading v7...
I'd like to reciprocate Iain's comment - so more likely he knows twice as much.... (or is that the reciprocal?)

Re: Update project to F10
You need someone with version 7 to convert (last version that can load the old v5 format) - if you PM your file to one of the VCs (myself, chipfryer27, medelec for example) we would do it for you - or post here? There have been some changes to components etc, so it might take a little work after fil...

Re: 2x 74HC595 via SPI interface, driving 8x 7-segment display
The 74HC595 devices are daisy-chained - so writing values will 'push' the data to the second chip... So you just need to write sufficient data for both devices before latching the data. I haven't used this - but the MAX7219 works in a very similar manner.

Re: 16f18877 internal Zero Cross Detector
Found the issue - unplugging the PICKit and the speed increase at which it works is dramatic - I changed to using 32MHz internal - and running happily at 100kHz (with mods as per previous post)
