Tiger Application Notes

Control bipolar stepper motors

It's right - we already had stepper motors (Application note 018). But there is good reason to recall this topic. One is that we then built a discrete solution for the motor output stage, now we try a more elegant approach with the H-bridge IC SN754410, which we successfully tried with small DC motors (Note 059). Another reason for the new beginning is, that we want to control bipolar stepper motors this time, which have a simpler structure and are less expensive.
Switching off the Tiger when not in use

Did you ever turn down a battery supplied project with the BASIC-Tiger, simply because it uses to much current? This is especially annoying when the BASIC-Tiger is supposed to work only now and then in the planned application: Yet its current consumption is rather high even in idle times. Think about e.g. a control with two small motors, which have to sensitively swing and rotate a video camera. Once you have your object in focus, all motors stop. Yet the BASIC-Tiger want ca. 50 mA and this is not acceptable for batteries for longer durations.
Motor control with H-bridge

Do you remember the experiments with DC motors from application note no.19? You like to relieve the BASIC-Tiger or simply control a larger number of motors (e.g. for robotics projects)? Then this application note shows a clever solution how to control up to 62 motors in both directions with 127 speed steps each with moderate computational effort and minimum pin requirement.
Finally communicate wireless!

This progress can be found in many applications. Certainly it is also possible for the TIGER products. By using infrared technique by "IrDA" a wireless communication to almost all notebooks, many cellular phones, as also to current PCs can be enabled. Finally the end of set of wires. This application note shows how.

SMS per BASIC-Tiger

The TIGER computer modules are sending SMS. Today the communication with cellular phones or modems is very popular. This application note describes the possibility to send SMS with a commercial cellular phone. As there are countless fields for such an application, e.g. alarm systems, surveillance applications etc., that usage of the TIGER family could mean extension possibilities for anyone's applications, or a quick and successful entry.
Jumbo display for your project

Jumbo displays! Does your application need a large display? How about a 7-segment display? It could also serve as extension of your current applications! This clear application note introduces you to the concept.
Control servos with EP16/17

The control of servo motors is a field frequently needed in the industry. Therefore Wilke Technology GmbH offers a growing range of solutions. Regarding the new expansion modules EP16-Servo8 and EP17-Servo16 we would like to offer additionally an application note introducing this expansion modules, as also demonstrating the processing of the control commands.
LPT bit pattern generator

As an experienced BASIC-Tiger user you know the RS232 interface. From the PC also the LPT interface (Line-Printer) isn't new to you, which is also known under different pseudonyms: Parallel port, printer port or Centronics interface. Tiger-BASIC offeres device drivers which make this interface usable for the BASIC-Tiger. The main task of the LPT interface traditionally was always operation of a printer. But that is not the topic of the present application note, we want to use the LPT interface of the PC as a tool for electronic experiments, which can save a lot of work working with the BASIC-Tiger.

Another interface that the BASIC-Tiger can handle without a problem. The USB interface is widely spread and used very often. This application note shows, how the BASIC-Tiger adopts this interface and how you can make use of it in the future.
A UPS for the BASIC-Tiger

Safety! That is the main term describing this application note. It is demonstrated how your precious work is secured by the simple use of a GoldCap. This safety can be ensured on smallest space and a possible power failure is reliably handled. If this measure of safety is needed in your application, here the simple handling is presented.
An eye for the Tiger

You need a digital picture processing or an optical picture recognition, for e.g. an alarm system or a bar code scanner? This application note shows how you can realize such a project with a CCD sensor at the BASIC-Tiger.
