    ...performed. -drive a Mosfet driver @ 1 MHz to create an acoustic signal -perform a 12 bit ADC on a signal coming from a sample and hold amplifier (highest conversion speed possible) and store the data with precise arrival time in the internal memory -the key to system operation will be its timing. There are 7.37 MHz clock and 32.768 kHz external timers to work with. The dsPIC must trigger PWM to drive the MOSFET at a certain point, complete the transmission and then change to receiver mode. The sample and hold amp must be flipped to HOLD at a specific time and held long enough for the ADC to perform a full conversion (it would miss a 1 MHz signal otherwise). Clearly, this is not a one step project and will require collaboration in order to get the system running. S...

[I would prefer to have the program use the PWM functionality of the uC, and not 'bit-bang' the whole thing. See TechNote item "d", below.] This is a Phased project; please bid on Phase1 at this time. Please take a look at all Phases. Don't consider this project unless you a) have access to a 16F737 and a breadboard to test with, b) are familiar PBP,? and c) are interested to pursuing the project to completion.

    ...2-wire connection to a DC motor, with polarity not fixed. This motor does not run in continuous mode, but is operator-controlled for short periods. The 2-wire connection is to be interupted and a device placed between the source and motor. The device will initially pass a portion of the applied voltage, ramping up to nearly the full source voltage. The preferred method of output voltage control is PWM (16khz-32khz) but implementations utlizing analog methods will be considered. Upon application of voltage to the 2-wire supply: Within 3 ms voltage is passed out to the motor at a reduced level (the threshold level) persisting for 0.2 to 0.4 seconds, at which time the output begins a linear rise to maximum at 1.2 to 1.4 seconds. Output continues at maximum until supply is interrupte...

    I have legacy PIC assembly code for a 16C54 which creates three unique PWM outputs, switching between them based on input. Output are: 1. Stand-by mode. Fixed PWM. 2. Ramp-up mode. During first mirco seconds of applied Gate-input, increase pulse width from Stand-by pulse width to ON-mode pulse width. Duration of ramp-up is variable. 3. ON-mode. Fixed PWM. The legacy code has input in parallel: 8 bits representing 0-100% pulse width. Even with tight code running with a 20mHz oscillator, it’s too slow for my new requirement (slow in the sense of switching between the 3 modes.... each clock-tick counts). I need: a) Port the code to a new PIC: 40mHrz 18 pin DIP. b) Implement programable frequency (the legacy code is pulse width only). c) Change ...

The application needs to be language independant which will require you to create XML language files external from the application so our distributors in other countries can modify for their users. We will provide the hardware required for you to interface a vehicle and the source from our 3.6 application, but you must have access to vehicles supporting our ISO, VPW and PWM interfaces for development and testing purposes (see for more information). The current application has about 5,000 lines of VB.Net code. The 4.0 version will also need to come with documentation (Windows help documentation, built into app). We will provide a license to InstallShield 5.0 as well as licensing for Dundas Charts for .Net. You will need to work with us on the licensin...

    I have developed a program using a PIC Microntroller 16F84A. The PIC basically works as a 4 channel Digital to Analog Converter. It receives a signal serially and then uses Pulse Width Modulation to individually alter the voltage on the 4 outputs between 0 and 5V. The code I can supply basically works but needs some improvements in relation to PWM part. The trick is to alter the code so that the output voltage remains the required level while the PIC is busy receiving the asychronous serial data. At the moment the code works like this: GetValueSerially (Between 0 & 255) TurnTheOutputPinOn Do IncrementCounterByOne If ValueReceived = Counter then TurnOutputPinOff loop As you can see if the value 1 was received then it would be turned off as soon as the counter hit1. Ie it theoreti...

    I need a simple program that can toggle up to 4 parallel port pins. I will use these a PWM signals. I want to set a frequency for the rate at which the signal is strobed. Also I want to set the percentage for the ontime. For exapmple if I set the rate at 40 KHz with a 50% duty cycle I want the pin to be high 12.5 micro sconds and off 12.5 micro seconds. If I choose a 80% duty cycle I would want the pin to be high for 20 micro seconds and low for 5 micro seconds. I need at lease 4 pins that can be controlled seperately. I need this program to help me test some hardware that I have made for school. Programming is not my thing. ## Deliverables 1) Complete and fully-functional working program(s) in executable form as well as complete source code of all work done. 2) Installation ...

    ...LEDs arranged in vertical pattern to replicate flicker of real candle PWM or PPM, preferably,**Must** be able to dim and fade LEDs , **NOT** just full on or off. Vary flicker depending on wind input from simulate flicker of candle in breeze and steadier flame in still air. Allow for poteniometer sensitivity for wind sensing thermistor. This is at maximum three channels of PWM/PPM and one of A/D the smallest 8 pin microcontroller should be useable. Though the deal is for the ASM and HEX files for the selected microcontroller am not concerned if these were generated from a C or Basic compiler. This is a microcontrolled version of an accepted anlogue circuit, the pwm/ppm is neccesary to simulate filament lag with faster responding LEDs. ...

    ...two pulses have a constant period of 18ms. One signal controls left and right motion the other forward and reverse. The duty cycle gradiates from 1.2ms (100% left/rev) to 2.0ms (100% right/fwd) with 1.5ms duty cycle for nuetral on both signals. The ideal program would take advantage of the on-board A2D 10bit converter, mesh the two signals with good resolution, and output the signals driving the PWM outputs which in turn drive separate h-bridges...
