As a general point, always check the errata on the Microchip site for your part. They state the known problems with the part number; almost all chips have some errata. I ran into a BOR and low-power sleep problem on the 18F86J11, at least with the batch we bought 2 years ago. I ended up giving up af...

Topic: Can someone help me with this Syntax Analysis?

Hello, I'm not sure this has anything to do with Swordfish. Are you a student taking a course in compiler design? Most computer science courses start with Pascal as a language, because of the tight rules and so much of the syntactic elements are transferable to other languages. There is a similar de...

You are welcome, I'm glad to be of help. I like to check this board from time to time....there is an active, helpful community for SF (including David Barker himself, the SF author) that helped me when I was starting out. So now that I have a bit of experience with the product, I like to contribute ...

Running the M41T82 RTC

Hello MichaelL, I put together a little checklist that may be of help. 1. RST line held high with a pullup resistor (say 10K) to ensure it is high. Note the other pins on the chip that must be held high/low on p. 9 of the datasheet. 2. Use a 32 kHz watch crystal with the suggested board foil layout....

Hi ohararp, The code formats are not that much different from the SSD1339 code I put up. Of course there are some different functions in this chip. They also dropped the "graphic" functions, like being able to draw a circle with one command. One nice improvement is that I see Solomon now has compens...

Hmmm....I've been looking at these WiFi modules myself. I have a thought....and it's probably more work than just writing everything in C, but I'll post it here.... If the asm from the C code has clearly defined variables that can be called from SF within asm blocks, maybe the C-produced asm could b...

Yup, I agree. RS232 to USB rocks. Try the FT232R USB UART IC. But remember, whenever you are going slave-to-slave, you will have to write your own interface code. That means it will be purpose-built for your devices, unless you can put in a manual switch from "normal" USB slave mode to "comms" mode ...

Very cool! Have you tried programming the whole 16 MB? What sort of programming times are you seeing to conduct this?

It would be interesting to experiment with some detailed graphics on the chip, even try some video on a colour display.

OH, no, don't tell me someone cracked the USB key?? Some people will steal anything!! (notwithstanding fan images of Grommit....)

I'll ask XOR to send you a note, hopefully he has a record. It's been 3 years now. My, how time flies when having fun :^)

Great to see you got that routine going. I hope my old SSD1339 code was of help! The SSD1339 is now obsolete so I'm looking for a replacement. It would be fantastic if there was such a thing as an OLED that was compatible with an LCD from the same company so that I could substitute the LCD where app...

I found the same problems a couple years ago. Running subs with local variables while in an interrupt was not a good idea, your experience supports that. The way I got around this problem was not to run subs with local variables in the interrupt but to set a state machine variable when in the interr...

Sounds like a job for Perl or a shell script. Perl has a "system" command that can launch applications with parameters:

system("start c:\dir\program.exe -parameter");

Is that the sort of thing you wish to do?
