Introduction

The objective of my web site is to foster tinkering. In my mind, this is the way people learn best.

Please note that proceeds from sales are used to buy additional stock, but more importantly, to buy equipment for development of the material on this web site and to pay students to develop material. Sadly, much of the web has become nothing more than a shopping cart with no development overhead. Please consider buying from vendors who not only sell, but also are striving to advance the craft.

My only advertising is word of mouth.

Please note that I am not in a position to do consulting.

I prefer payment via PayPal. However, please use the PayPal buttons only for shipping in the US. PayPal will "automatically" calculate shipping. However, in many cases, this is too much and I will refund any excess shipping, at least to within a dollar.

I no longer process credit cards and rely totally on PayPal.

For International, please send me e-mail (pha@phanderson.com) for a quote on the shipping.

Microchip PIC..

Development.

• Microchip PIC PIC16F87x Development Package. Now includes the Olimex TinyICD2 with 16 VDC wall power unit. $124.95. (US and Canada Only. Others, please contact me.) (Out of stock).

• Olimex TinyICD2, with compatible 16 VDC wall power unit and six foot serial cable. $54.95. (Out of stock).

  Note this is compatible with the Microchip ICD2, but uses only an RS232 Com Port.

  The design does not include a charge pump. Thus, a source of 16VDC must be used to power the ICD to provide the 13 VDC required for programming the target PIC. (This is included). I also power the target (+5 VDC) from a source other than the ICD to avoid heating the small ICD2 unit.

  This may be used as an ICD for many of Microchip's latest parts and also as a programmer. For a complete description of compatible PICs, download the latest version of MPLAB and see the "readme" file associated with the ICD.

• Olimex In Circuit Debugger 2 - $89.95. (Out of stock).

  Same as Microchip ICD2 except does not use the bulky tel connector to the target used by Microchip. Microchip Users Manual. This may be used as an ICD for many of Microchip's latest parts and also as a programmer. For a complete description of compatible PICs, download the latest version of MPLAB and see the "readme" file associated with the ICD2.

  Includes main ICD2 unit and USB Cable (A Male to B Male).

PIC Programmers

These were inteneded for use with the WARP-13 Programmer.

• ZIF Socket, Textool/3M, 18-pin, gold - $9.95
• ZIF Socket, Aries, 28-pin, tin - $9.95

Olimex Serial Port Programmer

• PIC-PG2C - $13.95. See Notes. (Out of stock).

  The original COM port used levels of nominally -8 VDC and +8 VDC. This programmer uses this nominal 16 VDC swing to generate the 13 VDC required by the PIC during programming. Many newer PCs, laptops and USB to serial converters use lower levels, say -5 and +5 or GRD and +5 VDC and thus, this programmer cannot develop the required programming voltage and it will not work. (It might actually pay to keep an older PC around).

  If you have a voltmeter, measure the voltage at term 3 of your COM port (9-pin) relative to terminal 5. If the voltage is more negative than nominally -8 VDC, the programmer will most likely work for you. If it doesn't, you may return it to me for a full credit, less shipping.

  There is a six terminal connector and cable for In Circuit Serial Programming (ICSP). I caution against using this to connect to external circuitry. Rather, use the on-board sockets for programming.

  I offer caution as the negative rail of the PC Com Port, nominally -8 VDC, is used as ground on the programmer and this is fine so long as the programmer is isolated from other circuitry. However, in using the ICSP connector to wire to a PIC in a circuit that is referenced to ground will cause the PC Com port's negative rail to be connected to ground. The programmer will not work.

  I was initially skeptical of this programmer. How could anything so inexpensive do such a good job. However, I have sold over 1000 of them and the PIC enthusiasts have been pleased. I have used this successfully when my trusty WARP-13 and PIC Start Plus were unable to program a new device.

  A general note to the hobbyist community. This programmer is a good buy. But, if you are serious about using PICs, the "best" programmer is a Microchip ICD2 or a clone. I normally sell an Olimex model. These may be used as a debugger, but also as a programmer for most modern PICs. They integrate into the latest version of MPLAB and Microchip is pretty good in keeping their software current.

PC Parallel Port

Note that these books were developed prior to the popularity of Windows and one could actually run DOS and there was only one type of parallel port (now termed SPP). All routines were written using Borland's TurboC Version 2.0 for DOS and I still use this old compiler in teaching as it is simple, has a good debugger and will run on any PC. This is now available for free download at Borland Community. Click on "Museum".

I have no plans to update these books for Windows.

Although the platform, a PC running DOS with a Stnadard Parallel Port, may not be as practical as it once was, these books offer a wealth of information in interfacing with the real world. Indeed, they were written for a Parallel Port, but one might argue that a port is a port, whether it be a 8051, 68HC11, PIC, BX24 or Basic Stamp.
