This P2 Quick Byte demonstrates the use of the 24V 4000 RPM BLDC Motor (featured in the September 2022 “Propeller 2 Mystery Box”) but it is also compatible with the 6.5″ Hub Motors. Description The 4-channel Universal Motor Controller add-on…
Description Connect the boards together as shown and double-check the correct orientation of each item. Connect a suitable 5V power source and ensure the boards are powered on by observing the green VIN light on the WiFi module. Using a…
Description Forum member rogloh created this easy-to-use text driver API layer that simplifies the setup in his VGA/DVI/TV driver for a single 16-color text screen at a given resolution. This self-documented driver works in both Propeller Tool and FlexProp. Some…
Description The jm_analog_in_multi.spin2 object supports up to 32 ADC channels that can measure from 0 to 3.3v. The object is easily configured with a base pin, channel count, and low and high scaling factors that provide meaningful output from ADC…
Description Most of us begin our experiments with microcontrollers by blinking an LED; this is the microcontroller version of the “Hello, World!” program that is introduced in traditional computer programming training. On the P2, we can blink an LED like…
Description The jm_dhtxx.spin2 object wakes and reads data from the DHT11, DHT22 and CM2302 Humidity and Temperature Sensors. In the top file, configure the S_TYPE for the sensor you are using (DHT11 or DHT22). The CM2302 should be set as…
Description E-Ink (Electronic Ink) displays are commonly used in low powered applications and mimic the appearance of print on paper. They are widely used for the paper-like displays used in e-readers, and now are easy to use with Parallax P2…
Description This program demonstrates how to series-connect five pushbuttons over one I/O pin, so that they can all be read in parallel by taking an ADC measurement and scanning a threshold table to determine their binary pattern. The program includes…
Description These instructions demonstrate the upgrade of an Arlo robot from Propeller 1 to Propeller 2 control with the new Parallax Universal Motor Controller Add-on #64010. The operation and example code are demonstrated in the included video. The example code…
Description The Ping))) object provides the distance from the sensor connected to an I/O pin through a 3.3k to 4.7k resistor. The object returns the distance in microseconds, or a 0 value if missing or bad sensor. The example uses…
