he LPC932 can be used to create a Pulse Width Modulated PWM signal. That s an analog signal, with only 2 discrete levels, for example 0V and 5V and a conSTant period. The current value of this signal at a certain poiTnt of time is proportional to its Duty Cycle. That s the High Time during one period divided by the period. It can also be calculated as the average value during a particular period. That means after low pass filtering, (e.g. RC circuit) the signal becomes analog, with an actual value controlled by the microcontroller. The PWM functionality enables the LPC932 to control for example the speed of DC motors or the brightness of electric lighting.

One-channel queuing system simulator (M/M/1) * Arrival and service times are random and distributed exponetially. * * The simulator is time-slice-driven, i.e. the system model is being * run at discrete time points, with conSTant increments deltaT. * At each such time moment, program checks if a new item arrival or * release has occurred during previus deltaT.

CORDIC (Coordinate Rotation Digital Computer) is a method for computing elementary functions using minimal hardware such as shifts, adds/subs and compares. CORDIC works by rotating the coordinate system through conSTant angles until the angle is reduces to zero. The angle offsets are selected such that the operations on X and Y are only shifts and adds.

This example provides a description of how to use a DMA channel to transfer a word data buffer from memory (Flash) to memory (RAM). The dedicated DMA channel is configured to transfer once a time a 32 word data buffer stored as conSTant in the Flash memory to another buffer in the RAM memory. The received data are stored in the DST_Buffer. The DMA channel transfer complete interrupt is enabled to generate an interrupt at the end of the buffer transfer. As soon as the transfer is completed an interrupt is generated and in the DMA channel interrupt routine the transfer complete interrupt pending bit is cleared. The data counter is stored before and after the transfer to show that all data has been transfered. TransferStatus gives the data transfer status where it is PASSED if transmitted and received data are the same otherwise it is FAILED

This demo shows the use of the PWM block in generating the pulse waveform whose duty cycle is changing regularly. The PWM waveform period is variable, while the width of the pulse remains conSTant.

This example demonstrates the use of the ADC block and PWM blocks. The generated DSP code produces the pulse waveform whose duty cycle is changing as the voltage applied to ADC input changes. The waveform period is kept conSTant.
