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...

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 ...

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...

Stealing Code Bad. So Dongle Good. Can I simplify this for anyone who didn't understand the statements above? I have a couple copies of SF now, and since we buy the dual-dongle version, we always have a spare. SF is installed on numerous machines that we use depending on where we are and what we're ...
