PWMPAL monterar du som en "exrea sockel" under din BASIC Stamp, och vips, så har du fyra individuella PWM-utgångar på stampens I/O-pinnar 12, 13, 14 och 15. Dessa PWM-ugångar arbetar helt självständigt och får sina kommandon seriellt från stampens I/O pinne 0. PWM-pal kan också användas som fyra fristående räkaner, då räknare den pulser på I/O pinnarna nummer 11, 10, 9 och 8.

PWM-pal är en perfekt avlastning för STAMPEN i krävande realtidsapplikationer. Läs manualerna som du hittar här nedan för många spännande exempel..

The PWM channels can be configured to operate under software control, or under hardware control through the corresponding counter input channel. In addition to PWM waveform generation, the PWMPAL has four 16-bit counters that operate at all times, even when the counter pin is used for hardware PWM control. Communication with the PWMPAL is handled through a bi-directional serial connection on pin P0 of the BASIC Stamp microcontroller. The Parallax AppMod communications protocol is used, allowing baud rates of 9600, 19,200 and 38,400 baud. PWMPAL demonstration software files may be downloaded at the bottom of this page.

Examples of PWMPAL Uses:

• Servo or DC motor control for robotics and animatronics
• AC waveform [square wave] generation for bi-color LEDs and sensors
• Background counting for process control, robotic motion monitoring, etc.

• Up to four simultaneous PWM outputs
• Independent control of each PWM output high-time, low-time, and phase
• Generate frequencies from 0.3 Hz to 20 kHz; duty cycle independent *
• Outputs may operate under software or hardware control
• Up to four 16-bit counters
• Auto-baud detection (9600, 19.2K, 38.4K) for Stamp-to-PWMPAL communications
• Requires no PCB "real estate" – mounts underneath BASIC Stamp module
