Products New Products Specials! The BASIC Stamp 2 module serves as the brains inside of electronics projects and applications that require a programmable microcontroller. The displays that feature 4 lines of 20 characters behave as if they consisted of 2 lines of 40 characters. The logical state of either line is thus high by default and becomes “0” only when it’s actively pulled to ground by a conducting transistor. The installation puts a “Basic Stamp Editor v2. The charge on the capacitor has essentially mucrocontroller to go when the microcontroller pin is in its high-impedance state.

A slave can deny access to a master at any part of a write transaction from the master’s perspective or at the beginning of a read request simply by doing nothing, instead of pulling SDA low before the master issues its ninth clock pulse.

Using the BASIC stamp microcontroller from Parallax – Numericana

Ultrasound sensors on SensorWiki: Serial baud for programming Dimensions: The sawteeth in the blue “sinewaves” are part of the signal at this point, as will be discussed in great detail shortly. We dedicate a pin to properly trigger a Rigol DSE oscilloscope: Note that micorcontroller BS2 uses push-pull on both bus lines in the relevant primitive, instead of the open-collector architecture I2C is based on.


So, we have to find some hardware solution to the problem of allowing software to control the audio volume. Before I even touched this unit or looked at the online documentation, I had a few fun applications in mind for this initial review.

BASIC Stamp – Wikipedia

Unfortunately, it did not. Time, speed Doppler shift and attenuation of ultrasound. It is able to control and monitor timers, keypads, motors, sensors, switches, relays, lights, and more. That circumstance can hardly happen at all on the SCL line, which most slave don’t even have the circuitry to treat it as anything but an input.

Other Similar Parallax Products: The BASIC Stamp 2 serves as the brains inside of electronics projects and applications that require a programmable microcontroller. Then, we’ll discuss PBASIC software to support that configuration and turn the whole thing into the educational experience it was meant to be.

Quantity Add to cart. Otherwise, the and the board we’re reviewing here are equally suited as starter sets.

Filtering that square wave will result in a signal proportional to the DC level used. The first task is to identify your board. The supporting software will recognize possible input combinations from this: At left is the standard 5×8 matrix font for the HD Mkcrocontroller units without backlighting have connectors with only 14 pins instead of.

If you must know, so do the codes of the custom characters. The first bad day for the DS comes only 59 days after the DS will fail for lack of a “century toggle”. It’s the next best thing. A master can drive the I2C bus with arbitrarily low speed, so a sluggish microcontroller, like the BS2, can easily be a master of an I2C bus.


The two sets of forbidden entry points at the “end” of either line and behave exactly like the valid beginning of the next line 64 and 0, respectively. Don’t even think of allowing the BS2 to share an I2C bus with other masters or with slaves that can “hold the clock”. In practice, this means that the characters you defined for codes 0,1, I don’t recommend that shortcut at all.

For the more advanced part of the following review, a text file is provided with the source code for a tiny operating system and drivers for a parallel LCD unit and a synchronous serial bus I2C connected to a real-time clock RTC with a temperature-controlled crystal oscillator TCXO. The slave changes the state of the data line SDA in blue, just after each clock pulse. In practice, this word of caution only applies to the writing counterpart of the 9-bit read discussed above.

In this section, we’ll complete the process by endowing the unit with a key keypad. For customers that require a more powerful, multi-processing microcontroller, we recommend the Propeller microcontroller.
