    We look for an implementation of Art-Net 4 and RDM based on our implementation of DMX. We are using a Cortex-M 4 MCU (Artery AT32F-415 RCT6 MCU) The AT32F415 Series Reference Manual V1.04 can be found here: The implementation should be as hardware independent as possible, therefore the implementation of Art-Net is planned on the cortex-M 4 MCU and the UDP data from the ESP module is being transmitted using throughpass and SPI link. This is the specification of RDM: You can use various open source implementations for our implementation. This is an example for a RDM implementation: Similar for ArtNet: An implementation of DMX is being provided. Design and Implementation Constraints The software should be programmed in Standard C.

    An automatic Braking system is an intelligent mechatronic system includes an Ultrasonic wave emitter provided on the front portion of a car producing and emitting Ultrasonic waves. An Ultrasonic receiver is also placed on the front portion of the car operatively receiving a reflective Ultrasonic wave signal. The reflected wave (detected pulse) gives the distance between the obstacle and the vehicle. Then a microcontroller is used to control the speed of the vehicle based on the detection pulse information to push the brake pedal and apply brake to the car stupendously for safety purpose.

Both systems can hear or cool the house but at this moment a lot of times the systems are working against each other because the temperature that is wished, is not synchronising. Maybe this can be done with modbus or something. The project is: -selecting the right hardware -maybe write some programming language -With the right instructions I can connect the hardware myself easily. I have attached the NILAN specifications.

Then I’ll need another 16 pin vertical female header for the lcd screen (pin 1 from the adapter would need a trace going to pin 1 on the lcd adapter board, 2 with 2, etc.) As for the components I’ll just need holes so I can solder them.
