    I am looking for a skilled MCU programmer to write code for (2) sets of adjustable PWM signals both need to be inverting and noninverting square waveforms The frequency: (0-100 Khz), needs to be adjustable via an internal or external (20K) ten turns potentiometer. The duty cycle: (0-100 %), needs to be adjustable via an internal or external (50K) ten turns potentiometer. Also needed is some code written for a feedback loop via a current sensor on the tank section of the induction heater for safety reasons. It's important that we also have code for a digital PID temperature controller that we have it has a type-K thermocouple input and it needs to be connected to the PWM outputs in some way for good temperature control. Lastly, the STM32H735G-DK evaluation kit needs...

    I want a very simple DC motor controller with these features: 1- Input 9v Alkaline battery 2- 12v, 5W DC motor 3- Capability to adjust the motor speed (using PWM preferred) through a potentiometer 4- Low voltage, low amp switch entry on the board (2 wires) to start the motor. ( I will solder the switch wires later) 5- Green LED bulb that shows when motor is running (not a surface mount LED) 6- Red LED bulb that turns on when battery voltage is too low (not a surface mount LED) 7- Fixed timer that shuts the motor down automatically, even if the switch is on, with timer set to 5min (acts as a safety feature) I need the gerber files so I can move the components around if needed. To complete the project, I'm looking for an experienced freelancer who understands how to design high...

    I need someone who has experience programming stm32. The data from uart must be logged 24/7 for one to 3 months. Data will be draw on line chart, can be logged to CSV or whatever file. A file need to be save in daily to avoid cut off electricity. Data speed about 1 M bit per second. The board is simple which have 6 inputs, 1 PWM control. The critical is data login. I am learning STM32, too. I was hoping you could teach me how to program this STM32, too ( just for function used in this project). I have much experience in Arduino, but STM32 is different. I need your ethics and patience, and I want to teach. The project needs to be completed within a tight deadline of 1-2 weeks. Start from next week.
