BS2-IC (Parallax) BASIC Stamp 2 Microcontroller Module

So, we have a constant voltage at the output of the operational amplifier which will take a very long time to decay If Vee is too low, off-pixels are visible. Such filters microxontroller typically third-order or better In other words, don’t EVER use the following instruction unless you are absolutely sure that “frame” is even!

The slave is responsible for issuing an ACK bit after each byte transferred.

We’re already halfway into this with the LCD provided above. A better solution is to connect the bicolor LED between P1 and something whose ,icrocontroller is opposite to that of P1 when P1 isn’t in the high-impedance state.

We’ll make imcrocontroller wiring compatible with one of the configurations supported by Parallax in the aforementioned specialized LCD primitives. One of them was generating DTMF tones. Follow the Getting Started steps. There are legacy serial versions of both units, which we’ll ignore here. Products New Products Specials! For customers that require a more powerful, multi-processing microcontroller, we recommend the Propeller microcontroller. Quantity Add to cart. The procedure described below should be made part of the initialization routine of any microcontroller with a reset button or any microcontroller which can be powered down independently of some devices connected to its Microconteoller bus.

The data sheet says that the oscillator can be trimmed in steps of roughly 0.


Pololu – Parallax BASIC Stamp 2 Module #BS2-IC

The idea will then be to use this in a carefully designed menu system, with or without the feedback of the LCD display. Parallax IDE for Chrome – The BASIC Stamp 2 serves as the brains inside of electronics projects and applications that require a programmable microcontroller.

The minimum purchase order quantity for the product is 1. However, this is not the way direct-access indices are organized.


Making the following procedure part of the microcontroller initialization will microcontrroller that situation and put any interrupted interface back to its normal state after every microcontroller reset.

The signal will slowly creep to the left if the clock is fast or to the right if it’s slow. Because the optimal “Vee” depends on temperature, it’s somewhat unpredictable and the user should be able to adjust it with a trimmer. The sawteeth in the blue “sinewaves” are part of the mirocontroller at this point, as will be discussed in great detail shortly.

At first, we may be satisfied with just one stage and a single capacitor. Such single-pin devices are indeed available but they happen to be much more expensive than the unit reviewed here Microcontrollrr master can drive the I2C bus with arbitrarily low speed, so a microclntroller microcontroller, like the BS2, can easily be a master of an I2C bus.

They currently do not support bit addressing or high speeds. Unfortunately, it did not. The installation puts a “Basic Stamp Editor v2.

Because of the above considerations, this is now moot. To do that we use the second high-impedance opamp in the IC Micrpcontroller or TL whose first half we’ve already used as an active filter. For some obscure reason, the latter solution is more popular than the former. Remember the Y2K millennium bug? Before I even touched this unit or looked at the online documentation, I had a few fun applications in mind for this initial review. At left is the standard 5×8 matrix font for the HD This is how the Stamp generates siwaves and dual tones.


Likewise, a master can end a reading sequence by not pulling SDA low before issuing the ninth pulse.

An I2C slave device must be able of recognize its own address quickly to respond to a master’s request. Then, we click “Getting Started” on the left-hand column.

The displays that feature 4 lines of 20 characters behave as if they consisted of 2 lines of 40 characters. This type of microcontgoller is beyond the scope of this article. Serial baud for programming Dimensions: It’s sometimes called a 5×7 font because the bottom row is blank in all standard characters to leave room for an underscore cursor. That’s all there is to it The first step is to produce a steady analog voltage from a PWM signal on some other pin.

Our Stamps in Class Educational Program was designed with this module, making it a great place to learn about microcontrollers. Feedback Comments or questions? The BASIC Stamp 2 module serves as the brains inside of electronics projects and applications that require a programmable microcontroller.

The BS2-IC is widely used in educational, hobby, and industrial applications and is strongly recommended for first-time BASIC Stamp users because of plentiful microcoontroller documentation, source code, and customer projects that are available online and in print.

On a multi-line LCD character display, the positions of the characters in a given line are always numbered consecutively from left to right.
