...Acknowledge the switches state transmitted from the PIC18F; 3 - Generate 2 PWM pulses (one from each ADC reading acquired from the PIC18F); 4 - Generate 2 output states (one from each switch state acquired from the PIC18F); 5 - Show PWM % for each output and switch state (from PIC18F) on LCD. The PIC18F board already has 2 buttons, but I need 2 more on different ports. The analogs on the PIC18F board can be placed anywhere (maybe AN2, AN3??). Please check the datasheet for the Demo Kit to decide where these peripherals are going to be placed () On the PIC32 board, there is an expansion interface. Please choose an output port that's free, doing the same with the PWM ports. The source code for the demo program is available in the Microchip
Redisgn my inverer sine wave program that use the 30f2010. Because the voltage regularion is bad and the Battery charger PWM is little bad. I must Add the overload routine and the low battery routine to have the inverter shut down until the public service power come back.
...control proposes the use of PWM technique to dim the LEDs ,The duty cycles of the PWM that is used to drive the boost converter is being reduced periodically. This reduces the average current flow into the driver circuit and hence, dims down the LEDs. To further boost the circuit dimming capabilities, the duty cycles of the PWM supplies to the time multiplexing mosfets are further reduced. 2) Fault compensation: ( this part need to modify from sample code) through the ADC pin in Arduino, we can sense the current flow in each of the LED string through the use of LM358 with a sensing resistor. Hence, when the one of the LEDs in the LEDs string is spoilt, it will be feedbacked to the micro-controller and LED failure protocol will be carried out immediately by ad...
Hello, I have a simple question. For a hobby project I am building a simple TENS muscle stimulator. To keep the electronics simple I want to use a simple boost switching converter. the PWM to power the inductor I will provide with an Arduino. Besides that circuit needs a simple switch to turn it on and off, to create a pulsating effect. This is also been done in the Arduino with a digital pin. So i really need only the booster circuit to create a high voltage for the muscles to contract. I have a simple schematic for this type of 'booster circuit', but I dont have the knowledge to find out which exact parts i need. I put the schematic in the attachment. I know it is the most basic booster circuit there is, it can be a little bit more complex than this :) I also want to...
Im searching for someone to help me write a program for arduino that will drive a PWM motor controller. Using RF I wish to have a tank style drive robot that is controlled from a 2 axis joystick. I will be using the arduino pro micro and a 434 GHZ transciever for packetized serial transmission of the data. I want the joystick to control all movement and I want the motors to be mixed. IE: If I push all the way right on the joystick the left wheel is going to spin forward 100% right wheel will spin backwards 100%. I can buy all my own components as I have included a picture of what I will be using. I can also provide links to all the products on 's website page. I dont know exactly how to hook it up so I might need some Fritzing files as well to help me with the connecti...
Hello! I'm looking to develop embedded software for the NRF51822 from Nordic Semiconductor based on the ARM Cortex platform.

SELECTION OF MICROCONTROLLER: As we know that there so many types of micro controller families that are available in the market. Those are 1) 8051 Family 2) AVR microcontroller Family 3) PIC microcontroller Family 4) ARM Family Basic 8051 family is enough for our application; hence we are not concentrating on higher end controller families. In order to fulfill our application basic that is AT89C51 controller is enough. But still we selected AT89S52 controller because of inbuilt ISP (in system programmer) option. There are minimum six requirements for proper operation of microcontroller. Those are: 1) power supply section 2) pull-ups for ports (it is must for PORT0) 3) Reset circuit 4) Crystal circuit 5) ISP circuit (for program dumping) 6) EA/VPP pin is co...

We have a control unit with Firmware that controls the temperature of a Kapton style heating board - there may be a bug in it and I wanted someone to look at the program and check the software is OK
I have an existing circuit that is running 6 RGB LEDs which have already build-in driver and 1-wire communication. I need to modify and using UV light LED. Probably, you will be not able to find a UV LED with the same footprint and same build-in driver. Which means you have to adjust the schematic and layout and probably use an external LED driver. PWM or current controlled driver to adjust also the brightness. Or a MosFET to just switch it on and off. (Depending on which cost less?)
My company requires a relatively simple design from the ground up using the PSOC4 from Cypress. This will be a simple ADC to convert incoming 0-10V variable voltage analog signal, and output a 5V PWM signal. The incoming voltage and outgoing PWM duty cycle will be displayed on a basic 16X2 LCD display. We can provide base firmware from a previous project written for ATMEL. We require from you 1) a basic schematic formed in the software of your choice (Cadsoft Eagle highly preferred) 2) a functional firmware. We are willing to work directly with you to test your design for you along the way - we are a well equipped manufacturing facility and PCB assembly house. This initial project is one of many to follow, to locate suitable candidates for our multiple future pro...

I need an LCD Driver Library written for AVR microcontroller (prefer Arduino IDE) that initializes the ST7541 controller via 8-bit (8080 interface), and allows to "print" text messages to a 128X128 monochrome display. Much of what's needed can be taken from other LCD libraries, and the basis is already done for you in some sample 8051 source code. You will be asked to "port" a very small amount of code from 8051 to AVR to demonstrate your skills and familiarity with build tool chains, including hardware interfacing.

Note: this is just a simple start to a longer motor speed control project. The goal is to create small circuit and a programming for an MSP430 (G2553 launchpad type would be even better) that generate a PWM pattern, controlled by 3 buttons. 2 PWM pattern should be designed: one is constant speed, another one is going from high to low speed then back to high on 2 second patterns. A button does change between one to the other. 2 other buttons are here to be able to modify the speed in the patterns. one to increase, one to decrease the speed. The output should be : -A drawing (even by hand) of the the components on a breadboard linked to the launchpad -the program for the MSP430 to be loaded using CCSv6 I have done such a circuit on Arduino but I am looking...
