If you have developed a product with Swordfish, please let us know about it. It's always great to here from people that have transformed an idea into a real world application. Just tell us a little about what you have done with a link to a webpage so that visitors can find out more.

Z90 SpectraScreen Panadapter

The Z90 from Clifton Laboratories made its debut at the 2006 Dayton Hamvention. Based around the 18F4620 PIC® microcontroller, the firmware was written entirely using Swordfish, which included a 320 x 240 pixel GLCD driver module based on the Epsom SED1335 chipset. Clifton Laboratories has just recently submitted two draft articles to the American Radio Relay League to consider for QEX, based on the Z90 design.

LP-100 Digital Vector Wattmeter

The LP-100 Digital Vector Wattmeter from Telepost Inc also made its debut at Dayton, apparently drawing rave reviews. Several magazines were interested in featuring the LP-100 in their new products coverage. Based around the 18F252 PIC® microcontroller, the firmware made extensive use of the libraries supplied with Swordfish, including the LCD library to drive the PLED used to display bargraphs and numerical readouts.

Rockwave Seismometer

Rockwave have just have completed development of a seismometer designed for the ‘keen amateur’ and education communities. Mechanically, the instrument comprises a horizontal pendulum made of carbon fibre, with a heavy brass weight at one end, swinging on a pair of low-friction tungsten carbide roller bearings. As the ground moves in response to seismic waves, the mass remains stationary, and the relative displacement is measured with a differential capacitance sensor with a resolution of 1 nanometre. The electronics are based around a PIC18F252, clocked at 20MHz, and a 16bit DAC for beam feedback. The firmware is compiled in Swordfish, making extensive use of floating point maths and libraries. A unique additional feature is the ability to generate synthetic seismic waves for teaching purposes and this part of the code uses Swordfish trigonometric functions. Readings of ground displacement are sent to a PC via RS232 and plotted on the screen.
