i am looking of some onto convert some arduino code to c++ with chinos/rt based OS from arduino code, i also need you to do the opposite. adruino uses atmega chip the chinos/rt uses stm32f100 and the last thing is i need to do help add support for a device to one of the codes. the hardware is a wii nunchuck replacement pcbs made specifically for controlling an electric speed controller.it has been made because current wireless wii nunchucks are unstable and have bad wireless connectivity. the wiiceiver is a pcbs that was deigned to plug in a wireless nunchuck receiver in and output pwm signal for and electric speed controller and servo. i need to make the wiiceiver read the axis and button presses from my nunchuck pcb. but i want my nunchuck pcbs to stay comparable with arduino so i was going to allow support for stm32f103 and them release arduino code to the public. ardunio code: https://github.com/jaustindavid/wiiceiver chibios/rt code: https://github.com/vedderb/nunchuk_mod

link to kicad project. https://drive.google.com/file/d/0Bym9XrdeViekWDZTSjZTRG1iTmM/view?usp=sharing hello , i have a project for you. this is an electric speed controller. this design is finished but i want to do 2 things to it. i want you to study it and design a way to join 2 together. i want you to join the positive and negative power inputs into the 1 and have them closer to the bottom of the pcbs. i want you to consolidate the parts so they share any parts that can be shared such as the voltage regulators usb and if possible the mcu. the second thing that i want you but is actually the priority, is do is make a second pcb using this current single pcb design and reduce it as much as possible. the current speed controller is made for 60v and rated for 100A i want to make one that is small and only rated to 10A at maybe 24v. the motor control ic that is currently used is the TI DRV8302 i want to replace that chip with the DVR8332 that has lower power ratings but also has...

I want develop wireless digital signal sender and receiver (RF transmitter/receiver) circuit to be developed. The device must be operated with 5V current (taken from USB) and input 5V USB signal to the wired signal sender. The receiver must be operated with 5V current (separate current source) and must receive 5V wireless signal and switch-on a 5V light bulb. When I feel confident on your skills I will give specification. And this involves electronics and software engineer (embedded system development). This is a small project which will be expended later. For now keep the budget as fixed $800. Be open and you can ask any questions if you want to continue truely.
