    Mam napisany program pod DUE, na wejściach/ wyjściach klawiaturka 4 przyciski, przekaźniki, sterowanie PWM do inwertera, wyświetlacz 20x4 przez konwerter HD, czujnik ciśnienia, czujniki temperatury/wilgotności. Program jest w dwóch wariantach- średnio zaawansowanym i niemal ukończonym. W pierwszym wariancie wyświetlacz działa, w drugim- pokazuje komunikat startowy i nie wyświetla nic (podświetlenie działa). Pomoc ma polegać na poprawieniu kodu tak, żeby wyświetlacz śmigał. Dodam że adres I2C jest poprawny.

    Potrzebuję nakładki na Raspberry Pi Zero, która posiadać będzie: - co najmniej 8 wejść ADC - co najmniej 8 wyjść PWM/DAC - kilka zwykłych I/O Proponowałbym to rozwiązać na jakiś ekspanderach Microchipa (np do PWM są fajne układy z serii MBI). Zbudowałbym to sam ale zwyczajnie nie mam czasu :( Wolę zająć się oprogramowaniem w tym czasie :) Urządzenie będzie służyć jako sterownik IoT do niekomercyjnych zastosowań. Potrzebuję dosłownie 2-3 sztuk takich płytek. Procesem wykonania PCB mogę zająć się sam. Chodzi mi tylko o projekt płytki i urządzenia które de fakto jest tylko ekspanderem portów. Jest to projekt hobbysyczny - stąd tak mały budżet. Zapraszam :)

    ...So I just need a schematic making. I am looking for a laser diode controller circuit. The diode is high power for engraving wood, I am looking at using the Nichia NUBM44 but open to other suggestions. Will obviously also use a heatsink +fan for cooling. The circuit should consist of three inputs, +VCC, GND and the PWM signal. pick your own values for source voltage and input signal but try to stick to standard numbers. I basically just need the diode to be controlled by the PWM signal, that's not hard to do with an NPN transistor and a current limiting resistor. Though I would also like something to make sure there is a constant stable current being fed to the diode, this is all about making sure the diode won't be damaged. Include the fan as a component if yo...

    need a code for following application: - It should produce 2 pairs of pwm signal between 20 -40 khz. - Innitial duty cycle should fixed at %40. But, after my tests I may need to change it to another value. So duty cycle should be easily changable in the code. And it should not affect the working princible. - 2 pairs will produce different freqs at a time. They should not be same at the same time. - In one pair signals's phase shift should be 180 degrees. (It will drive a pull - push transformer.) - The freq will change in around 150 steps. - The whole cycle will be completed in 16 seconds. After 16 seconds whole sequence will star over and so on. - It will feed by 12 volts battery system. If the battery voltage drops below 11.5 volts it should stop producing signals and should ...

    This project involves the design and implementation of a motion controller for a DC motor, incorporating precise speed control through Pulse Width Modulation (PWM) and real-time feedback using an encoder. The system utilizes an AVR microcontroller (ATMega328p) and involves programming in the C language within the ATMEL Studio 7.0 development environment. 1. **PWM Speed Control**: The heart of the system lies in its ability to regulate the speed of a DC motor through PWM. The PWM parameters can be configured and controlled, providing flexibility in adjusting the motor speed. 2. **Encoder Feedback**: To ensure accurate speed measurement, an encoder is integrated into the system. This feedback loop allows the controller to continuously monitor the motor speed ...

    ...the vehicle throttle beyond what the car computer can directly drive before tripping out on over current. I need an intermediate controller to boost the pair of existing pulse width modulating (PWM) 0-14VDC 5 amp signals (A and B per attached block diagram) from the car computer, into an identical PWM 0-14VDC but 15 amp current capacity (A' and B'). Your design (in green on the second block diagram) will ONLY have inputs from A and B, plus power and ground for 14 VDC at 15 amps. You will NOT have any access to other vehicle control systems whatsoever. Your design must replicate the same input PWM signals A and B exactly and instantly, just with more amperage, and output only A' and B'. I will need to review your schematic design, and will ne...
