Re: MacroSwap - Easy macro copying between flowcharts

Fixed - so for anyone who downloaded before - try again...

Amazing the havoc a typo can play :-(

Re: MacroSwap - Easy macro copying between flowcharts

Thanks, I think I slipped a version when I uploaded.

Seems to munge the flowcode badly..

Definitely did work - I'll have a play and repost..

Re: Upload problem on Arduino Nano 57600

Hi Leigh,

- Maybe - will check. That's a change - nothing in port instead of the COM3 or whatever.. Would explain why everything shifted left one place...

Re: UNO SCADA SPI Prescaler question

Thanks for giving us a pointer on this - it was interesting, I've not really used SCADA, to see how useful it can be!

Will have to have a more in depth play when time allows...

Re: UNO SCADA SPI Prescaler question

I just re-flashed a clone Nano - using a USB Tiny.. Much nicer working at 115200 :) But - no the baud rate shouldn't affect the SPI (and see new edit above about the 0,1,2) I've added a bug report about that... Something not quite right with the SPI on the AVR chips. I've put bug reports about the U...

Re: UNO SCADA SPI Prescaler question

Hi Peter, Have you tried loading the newer bootloader onto the clone Uno?

Upload problem on Arduino Nano 57600

After the latest definition file update for the Arduino Nano (57600) - the command line for AVRDUDE is incorrect. H:\>"H:\AVR\avrv5\batchfiles\..\bin\avrdude.exe" -p m328p -P 57600 -b "H:\Flowcode1.hex" -c arduino -D -U flash:w:"" avrdude.exe: invalid baud rate specified 'H:\Flowcode1.hex' Should be...

Re: UNO SCADA SPI Prescaler question

The documents aren't very clear? I'd guess the values correspond to prescaler of 4, 16, and 64 (ie clock of 16Mhz (FOsc?) / prescale) - the firmware calls SetPrescaler in the CAL SPI. (Docs don't specify here either) Edit - however experimenting in v8 (see below) - calling SetPrescaler with (2,4,8 e...

Const to Flowcode - Copying from C to FC made simple

Another project. Again based on an experiment I did on making a Flowchart viewer. This copies const or #defines from C to Flowcode - for me one of the problems with flowcharts is the hard-coded values. Easy to write but hard to maintain at a later date. This copies const declarations of the form: co...
