Thanks, I'll have another rummage through the fcd files.

It all seems to work quite smoothly for programs which is good.

Auto-detect doesn't pick the com port, but manually selecting it is fine. Using a long name looks a bit odd on the 'quick start' buttons - so a better name is needed.

I think I'm almost there - I created a fcd file AT4313_Dev_Board - and copied across the 'programmer' lines from a device that has a COM port (I used Arduino Uno) - this seems good - with the proviso that 'upload configuration now' gives fuse memory is undefined. I've not altered the fuse settings -...

... and I forgot to connect VCC to pin 20...

Which took rather longer to notice than you'd hope

I had most difficulty soldering the header pins - some melting has occurred on my VCC jumper :-( I hit two problems - it didn't work ( a biggy) - i checked the board carefully and I hadn't bridged the links in the power/ground rails.. Still no joy - and attaching a scope, I see that reset doesn't pu...

I made a small ATTiny4313 dev board. The MCI can run at up to 20MHz (or 8MHz internal) I breadboarded and it worked well, although the connection to the programmer was a little 'delicate' So using an ElectroCookie solderable breadboard i set to make a version with an ICSP header. This entailed cutti...

I can get the last .fcpx file to do the same.. Flowcode v10 (not sure of the version no?) New project - PIC 18f252 Components -> Search -> Display4x4 -> double click -> gives 'failed to add' then crash reporter. I can't replicate it quite today - but create a variable uint t[6][16] and paste in the ...

Yes, if you like... For example, the space tunnel would be a |_ shape and draw on four rotations - add a 'direction' parameter to Write8 (it would complicate it a bit, but it's not that difficult - use data bottom to top to flip vertically etc) I'd wanted 'big' 16*16 digits for a clock's alternate (...

I added both... Yes - a 16 x 16 character could be drawn as 4 8x8 blocks... Here a very simple demo (for simulation) - I call it 'space tunnel' :-) There is a Write8 and a Write16. 16x16 characters need 4 x the memory of 8 x 8 - so use sparingly in hardware? I found some interesting ways to crash FC...

As another thought - it would be easy to add a DrawChar macro that takes an array of data - so the client program would store it's own data. This could work with 16*16 (as Write) or possibly 8x8?

The LUT contains 16*16bit maps for 0..9. I got AI to draw the characters with limited success The LUT could be the extended to include other characters (either text or graphic) if needed (for example set char 10 to be ':' for your clock?) or go the whole way and use ASCII?
