TSOP 36 kHz. TSOP TSOP 38 kHz. TSOP TSOP 40 kHz. TSOP TSOP 56 kHz. TSOP TSOP 30 kΩ. IR Receiver Modules for Remote Control Systems, TSOP datasheet, TSOP circuit, TSOP data sheet: VISHAY, alldatasheet, datasheet. Description. The TSOP – series are miniaturized receivers for in- frared remote control systems. PIN diode and preamplifier are assembled on lead frame , the.

Precision of the measurement depends on the precision of the oscillator, here the internal RC-Oscillator. I wanted to determine how accurate this measurement is and used a quartz stabilised input frequency with prox 10kHz and performed measurements. The following chart shows the values and accumulated number of occurence. The x-axis is the the duration of 90 signal durations in processor clock time. The y-axis is the number of 'how often did this time value occur'.

For a perfect internal oscillator, you woud expect only one sharp peak. From the distribution you see the precision is a few permille.

The result is only one bit difference, please note the different scale on y-axis.. The two points together Dsummarize more than measurements. The frequency measurement mode needs lot of performance.

If signal frequency is too high, the controller will not be able to execute interrupt logic in time. I checked operation till 20kHz.

Precisely, the 10ms slot is more like 9,98ms. The t1-counter has 16 bits, theoretically you can measure up to 6. Accuracy depends on presicision of internal oscillator and is decreased by possible communication interrupts during the time slot.

Firmware: Infrared Control The controller can receive infrared controller signals.

The controller does not decode the signals, but measures time between signal edges and provides these for the host. The function needs to be enabled by configuration. After receiving a signal, the controller uses Port PD4 to indicate availability of data active low. The host will use GPIO 23 to detect this.

It is also possible to read status periodically polling from host. Data quisition is started by a negative edge edge 0.

Data aquisition is for max edges, each with 16 bit data. Resolution on 8MHz controller is 8us. If there are no signal changes for more than Typical breaks between signls are 60 to ms. Byte [1]. Older philips-remote control support this protocol.

If the protocol can't be decoded, ther will be error messages. There is a scratch-program in the scratchclient-distribution which graphically displays the timing. There are many similiar devices. Check frequency 38kHz , voltage 3. It is based on code from guzunty. Since the part is static sensitive Yes, I fried one while prototyping , take it out of its static protection bag by holding all three leads simultaneously between the fingers of one hand, then wrap a fine bare wire around the leads.

By picking up the part by all three leads and then connecting them together with the wire, no unequal voltage can build up on any one pin to damage the device. This will make it easier to form the leads without concern for damaging the part.

Deliberate Robots

The fine wire is removed after installation. Follow the diagram for general bending guidelines and adjust the leads as you go to fit it the PC board contact points. Take care to hold the leads close to the body of the IR module when bending them.

Holding just the body to bend the leads may damage the part according to some manufacturers.

A little extra care now can prevent problems later. Leaving the ground lead long will provide a useful handle when soldering the part onto the circuit board. It can be trimmed off later.

Clik HERE for a larger. PDF Note the safety wire wrapped around the leads to prevent static damage during all the bending and fitting.

One part of the wire weaves over the center lead and under the other two to assure contact. The wire is removed after soldering. After bending, fitting and trimming, locate the points indicted in the picture, and carefully solder the TSOP to the stock circuit board. Gently adjust its position to center it just behind the mounting screw and square and level to the board.

Final Modifications - A hole must be drilled to accommodate the IR module if the shell is going to be replaced. Finally, file or cut a square section toward the front of the shell. Test the Bug, and if all has gone well, replace the shell by lining up the pins with the sockets in the body and firmly pressing the two together.

If you get a preprogrammed device with e. In the appendix, the procedure is described for this. It takes approximately two seconds for the capacitor to finish discharging, and then the bridge goes back to the motor-forward state.

Unlike most electronic kits, all our kits include a schematic, detailed printed instructions, and teaching material explaining the why and how things work. The outer shell is held on with eight pins that press fit into sockets in the body. The two points together Dsummarize more than measurements.
