| C for the Palm Pilot the main web page for the latest PocketC is here an earlier version with less features is also available (this is also to be found in the C page) FREE ~ One version is free, the other is much updated, has a 45 day trial, and is available for a very reasonable cost. This file has the documentation and the source code for a h-dial and v-dial programs, some text output, some text and graphics, also a nice almanac where you enter the month and day, it gives you EOT, decl, hourly azi and alt, and sunrise/set data. AND a vertical decliner! AND an EOT and declination for 4 days on either side of a given day in a given month. June 2008 Some are packaged as xxxxx.prc (the xxxxx.pc is the IDE source code), some are compiled on PocketC on the PDA and executed from PocketC. In other words, two dials, two types of output, and two ways of running the programs. It is so simple that I did not add lots of notes. These dial programs work and have been validated, and you can amend the code for other dial types. PocketC notes are here, and the zip file with those notes and the C program for h and v-dials for the PDA are here, updated June 1, 2008 |

| The illustrating-shadows.xls spreadsheets have been reworked for PDAs, specifically the PalmPilot. The vertical decliner spreadsheet is shown to the left on a Palm T3. Display output has been reworked, hyperlinks removed and the sheets adapted for their removal, changes in formulae not supported by Documents To Go, size changes, and so on. The h, v, and v-dec dials are supported, three EOT sheets provided, analemmatic, armillary and equatorial dial calendar and hour data supported, calendar curves, and so on. |
