Swordfish

OK, this is annoying. I fixed up something I noticed whilst putting it up on this page, and having tested for a while here it appears to have fixed it. It was a unterminated string condition sometimes occurring in the ReadString function. Tested now with SUART and USBCDC test terminal, and things ap...

Hello All, I'm releasing a module for the low cost ESP8266 Uart to Wifi Bridge. EDIT:*** POSSIBLY FIXED *** { Please be aware that this is still a work in progress; there is a major bug in the module somewhere, but I have spent far too long on this module already and cannot seem to get to the bottom...

I have a number of general projects stuffed into the root project folder, then I have a number of projects separated into their own folders. Ie. testproject1.bas testproject2.bas testproject3.bas > project1dir > > project1.bas > > USBCDC.bas > project2dir > > project2.bas > > USBCDC.bas > Userlibrar...

Hi David, I know I'm late to the party here but is there any chance I could beg you to put in a switch for this updated library search behaviour, so I can force it back to the old way? Let me explain my problem: I have just come back to some new projects, and revising some old ones since this update...

How on earth do you find this stuff Jerry??!!?

I think you'd find a PDF generator in a PIC a real struggle to pull off. However, we had a very similar situation to you. To combat it we put in a checksum/hash output on the end of the file. This didn't prevent them from modifying it (or help if people we're just looking at the printed output), but...

If this is all you are doing on the device, could you double buffer your display at the cost of another 513 or so bytes? The 18F25k22 has plenty of RAM.

Then you modify one buffer whilst the display updates from the other, then switch them over at the end, and so on.

Ok, I've got this touchscreen driven menu system. Because it was done in a hurry the main logic and menu system are somewhat intertwined. I've got to rush off today, but here's the bulk of it It's not complete. I had to knock out some propriety bits so it won't compile or anything, but it should giv...

Excellent, glad it was of some use! Weird about the ASM comments bit. Never seen that. I'll change the WIKI from // to ' and move it out of that assembly section just to be on the safe side. Rangerbob Edit: Weirdly my source doesn't have those comments anyway. Perhaps I got carried away and added th...

Hi Tony, The reason your Seconds field isn't updating is because you cannot just flip the WriteEnable bit (RTCCFG.5). You have to send an unlock sequence first (see 15.2.7 WRITE LOCK pg. 167 of the datasheet). You have to write $55, then $AA to EECON2 then the immediate next instruction can flip the...

Blimey Jerry, that's a very useful and absolutely brilliant library! Many thanks for sharing, should come in useful sometime.

Personally I've only every really used the "Compare" function in the in-built string library. Not reinventing the wheel and all that.

You can have a look in the library to see how it performs it; using the FSRs and POSTINC registers. Seems pretty darn efficient to me.

The Easiest way would probably to use the High/Low interrupt vectors that these devices support. Put one interrupt to high, the other to low. Bear in mind that the low priority can/will be interrupted itself by the high, but for serial comms, you can probably put the ISRRX onto the low as there is s...

David, I think MrDeb... Sorry Toyman seems to believe that Swordfish should detect what PIC is mounted on his board and refuse to compile if it detects the wrong device is fitted.

Somehow.

Even though Swordfish and Pickit are two completely separate entities.

I created a "QuasiXML" parser for use in my Reverse Geocache . It was quick, dirty and nasty but it works a treat for reading and writing parameters off an SD card. At least it may be a useful jumping off point. { ***************************************************************************** * Name :...
