...------------------------------ We need someone to help conduct tests (non-destructive) on some of our recently developed embedded PCBs. The PCBs are in India so a testing agency in India is preferred but not required. Actual list & specs of these systems will be provided to short listed candidates. The PCBs operate like a PLC, have several RS485/232, TCP, Canbus ports, along with AI, AO, DI, PWM etc. Some of the testing will be stress, RFI, Temperature, humidity, electrical noise, vibration, PID control etc. Provide us the testing equipment and infrastructure you have. Also, list any other testing that you recommend should be done and test activities you cannot provide from our list. This is a temporary contract work. Please submit any test certifications or other relevant...
Write and integrate compatible code to replace the PWM rotary encoder input with a PWM input from a MPU 9250 9 DoF breakout board in the following Adriano sketch. #include <Servo.h> // Rotary Encoder Inputs #define inputCLK 4 #define inputDT 5 // Create a Servo object Servo myservo; int counter = 90; int currentStateCLK; int previousStateCLK; void setup() { // Set encoder pins as inputs pinMode (inputCLK, INPUT); pinMode (inputDT, INPUT); // Setup Serial Monitor (115200); // Attach servo on pin 9 to the servo object (9); // Read the initial state of inputCLK // Assign to previousStateCLK variable previousStateCLK = digitalRead(inputCLK); } void loop() // Read the current state of inputCLK {currentStateCLK = digitalRead(inputCLK);
I need someone to make a project file that works in Code Composer studio (CCS) to program the Texas Instruments Piccoli C2000 TMS320F28027F DSP Microcontroller. I want the development board to produce a PWM signal using ePWM1. The program should make use of an up-down counter. Once this has been done, I would like to have the opportunity to ask how this was done so that I can also code for myself and program epwm2, epwm3, and epwm4. That way I learn how to do it.
Halloween project - have two 12v dc motors and a full H-bridge with PWM and current sensing. Need a program to turn each of the motors in the same direction for ~30 seconds and then each to turn in the reverse direction for ~30 secs. I think this is fairly easy to program but the delay command does not (in my hands) allow both sides of the H-bridge to function in unison. Thinking that millis(s) programming is needed. Can send more details on the H-bridge, although it is not well documented. Need the controller to operate independently and not need a manual switch to change direction. H-bridge description at:

A STM32F4 eval / discovery ( such as STM32F429I-DISC1, but also similar develop board) generates a PWM to controls a H bridge to driver a DC motor. The motor includes also two hall sensors: the MCU reads pulses and drives the motor CW/CCW, following a trapeizodal speed profile (modulating the PWM duty cicle). Appling a CAN (in the following: CAN-OPEN) interface we use an external tool (such as a very simple PC interface) to communicate to the MCU how many pulses is the race of the motor. The setting up of the number of pulses, ramp slopes etc can be done via a simple PC interface (ieg Pyton or something very simple) that send via serial/USB or CAN port those parameter. This is a pilot project. The final job will be more complex and complete: this project will be updated wi...

...Note that space is quite constrained - the PCB with the LED mounts is quite small so it may be required to break the system into two boards connected via a flex cable or similar The LEDs must be able to be driven from a Raspberry Pi 4, with input from the GPIO pins. At a certain time only of the two sources (i.e. IR or white) will be active. The brightness of the LEDs should be controllable via PWM. Your task is to design a PCB with the above requirements with... 1. Analyze the power consumption of the system -- these are high power LED and an RPi has limited current supply to peripherals - your design must take this into consideration. 2.

You will need to write/port a new agent app basing on existining app example (all source codes included: assembler and C++). Agent is an advanced internet kiosk app. All statistics are stored on server, agent allows access control and count time, coins, etc: see features below. [1st.] priority task is to make agent work on Windows10 x64 (now works only on win7x64) and make all components 64bit (compile x64) Key components which need to be done are: (main app), (time counting panel), (sending lic to server & some other actions which needed to be researched cause source code is PARTIAL), (coins counter) which needs to work with just one USB coin counter machine (drivers provided) I.e. new app parts need to work the same as current but

Hi Evan. I have a project that is 8051 based. Command set is well defined, but we need to overlay a bit-banged I2C command set using GPIO pins. If you accept the project, we will make a good budget for you. The project is an urgent one. Let me know your thoughts. I'm from Detroit.
Hi Ciro L., If you accept this project, we'd create a good budget for you. We have an assembly language assignment that is based on the 8051 microcontroller. We need to essentially recreate an I2C command set and 'bit-bang' I2C on some GPIO pins. Do you think you can do such a thing for us?
The board will have 2 main functions. First, 4 gpios will be used to send PWM signals to a 4in1 ESC to control 4 brushless motors. (Wired control thru an ADC pin set) A tri-state 4 channel bus converter will be needed for outputting 5V PWM ( something like 74ahct125 ). Second function will be controlling a linear solenoid with onboard MOSFET and diode.(Solenoid power consumption Vout<20V, C~30A) The solenoid cycling speed/frequency will be controlled by a second pin set of ADC. 2 additional switch pin header will also be required to act as on/off to each circuit. Plus A USB C port alone with a reset and boot button. I want the PCB to be as small as possible. Less than 25x25mm/30x30mm. P.S. I want to have direct solderable pads on the board for Vin,GND and Vout GND for t...
