Swordfish

Hi, I have knocked together some code to talk to an AD9833 DDS for a project I am working on. It is bitbashed at the moment and could probably be vastly improved. It works well and I hope it can help someone else. The variable one_hz needs to be set up for the master clock used to drive the AD9833. ...

Thanks for your reply octal.

I changed some of the options:

#option GLCD_CS1 = PORTE.2
#option GLCD_CS2 = PORTE.1
#option GLCD_INVERT_CS = true

It now works perfectly.

Many thanks.

Hi, I am experiencing some difficulty with a 128 x 64 KS108 GLCD. I wonder if anyone can shed any light on this. I am using an 18F452 clocked at 6MHz. I am using example code to test the display, but the results are rather random, usually only 1 side of the screen is displayed and this is badly corr...

I too would be interested to know if these paths need to be set; I have tried adding the directories in c:\documents and settings, but I still can't get it to build. I would really like to be able to use my ICD2 with swordfish for a project I have planned, but this problem seems to be intractable at...

Hi, I'm trying to use Swordfish with MPLAB 8.10 and I can't get it working. When I attempt to build, I get the following error messages: Clean: Deleting intermediary and output files. Clean: Done. Executing: "C:\Program Files\Mecanique\Swordfish\Swordfish.exe" Test.bas -p18F452 Swordfish BASIC Compi...

Hi, I found a useful USB HID page: http://labs.mike-obrien.net/Document.aspx?id=hidlibrary I downloaded his HID library and knocked together a quick VB.NET program to talk to an 18F4550. It works very well indeed. If anyone would like to see the program that I used, feel free to drop me a line. Very...

Just as an update - CPC stock a good range of SD card sockets, including through PCB connectors.

They are reasonably priced, but the shipping charge is outrageous unless your order is over £25.

Very best regards.

Thanks for your reply Steve. Putting wires through the board was an idea I missed. I'll give the surface mount stuff a go.

By the way, your backup plugin & monochrome image converter have become indispensable around here. Thanks for those, much appreciated.

Very best regards.

I'd like to start using the SD card stuff but I'm having some difficulty tracking down a supplier of SD card sockets. Does anyone know where I can get them? I know that Toby Electronics do them, but they seem to be the surface mount type and I'd like a through board connector if I can get one. Many ...

I have solved this issue by doing bubblesort and median filtering over a range of values. Many thanks to Tim Box for his excellent code in the Stein Hart linearization code sample.

I was a little naive to expect perfect data everytime. Sigh.

Very best regards.

I am new to Swordfish. I have been experimenting with the DS18S20, an LCD and the USB CDC stuff. I am currently running 3 DS18S20's together. They are taking readings when requested by a VB.Net application. On a sample run of 100 readings, 32% were grossly inaccurate, with an ambient temperature of ...
