Swordfish

You could reduce the amount of time it waits at startup, but that can make it a bit harder to get into the bootloader.

If you go to the product page for the part on the Microchip website you'll find links to all the current documents

David has been kind enough to make Swordfish available for free.

If you're still talking about internal EEPROM in a 18F27Q43, the current datasheet (DS40002147H) specs it at 100K cycles (parameter MEM20)

are you saying this data doesn't get stored in eeprom ?

What I'm saying is that the bootloader doesn't support programming eeprom data from the hex file, so any initialization statements (like EEPROM = ) won't have an effect. 'EEPROM =' initialization doesn't produce any runtime code

I don't recall the UMC loader app supporting programming EEPROM (but I could be wrong).
I know the code in the .asm bootloader file has it disabled...

check your PM.

is it likely to be some kind of context saving issue ? It could be, depending on if you're trying to format and send the data inside the timer event. I wouldn't recommend that. Also, calling those timer setup routines (timer.initialize, timer,start) inside the timer event isn't a good idea. The eve...

The ConfigGenerator tool has gotten a facelift and some new features. It now allows you to import and export the settings to a file (it can even scan an existing .bas file for current settings). Another new feature is the ability to read the CONFIG settings from an existing .hex file, which can be h...

V2.10 released to correct IRQ errors in the DFP files for the Q40 and Q41 families

Attached are updated device files for the Q40/Q41 family.
I've also updated the SystemConvert utility to v2.10 which takes care of this error in the DFP files.

I just ran across this... There are errors in the current Q40/Q41 datasheets and mplabx DFP device files (which are used to generate the SF device files). The IRQ numbers for interrupt vectors 49-55 are incorrect (PIE6/PIR6/IRP6 show bit 1 is unused, and the IRQ's don't take this into account). The ...

The device register bit files in SF v2.2.4.1 now contain structure definitions similar to the examples shown in the wiki Using Bitname Structures These files are automatically generated from the MPLABX DFP files by the new SystemConvert V2 utility For example, the file "P18F26Q43.bas" contains // PI...

There is a new compiler update 2.2.4.1 available for registered users. You can use the download function in the IDE under 'Help | About... | Check for Updates" or Download: http://www.mecanique-web.co.uk/downloads/swordfish-si.exe and enter your activation key to install. You can view a list of chan...

The SetChan() sub uses the channel number setting for the ADC Positive Channel Selection Register, so it'll likely change depending on the device. Consult the datasheet for the ADPCH register settings. For the 26Q43 in the demo program the datasheet section 40.7.8 ADPCH shows: 000000 RA0/ANA0 001000...
