Find help, specifications and source code for the LPC900. The LPC900 challenges Microchip and AVR based on the worlds most popular 8-bit architecture the 80C51. With a 2-clock core the LPC900 series is a high performance, very flexible and low cost 8-bit microcontroller family. Designers using or interested in these devices are encouraged to share their know-how and ask questions.
The user's manuals suggest the pwm pulse width uses the timer clock. This implies p-clock or external clock is used to determine the pulse width and pwm frequency. Actually the pwm frequency is about 100 times slower than expected. Is the user manual documentation in error?
