It should use a usb connector to program the SAM21D in a similar way to the Arduino MKR Zero. The Atmel microcontroller will be connected to the SIM7020G in such a way to send data over LTE of course. Additionally, there should be 3 channels to measure voltage between 6-40v using the Atmel's onboard ADC. Cost of components should be a consideration. Designs should be submitted in Eaglecad format.

    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 3. **USART Com...

    I've got an AVR C project that uses a 10 position rotary switch interfaced to an ATTiny84A. Only 6 positions are to be used, and the position will be queued up with a single push button. The purpose of the dial is to provide input selection, to the ATTiny84A and will turn on power to either 1 or 2, of 3 PORTB pins. This will also require adjustment of PWM on several pins that I will need to adjust several times through the project. I would prefer this be done in Atmel studios as that is what I use, but any format in which I can adjust the duty cycle would be sufficient. This will most likely require software PWM on PB0 due to the use of PB0 through PB2. All the electronics for this project are in breadboard testing and can easily be changed if necessary. ...

    I want to generate an I2C slave with a SAMD21. This should have write and readable registers. Unfortunately I can't get this to work. I was guided by the following code: From page 39: The final application “High speed Configuration” in main.c file will be as below for SLAVE. The aim is to provide 256 registers (1 byte in size) with the SAMD21 (as Slave). The I2C master can write and read these registers. Your task is to create this functionality based on the provided example. Only the function "void SERCOM2_Handler(void)" may be adjusted. The I2C master works in FAST_MODE_PLUS. Therefore, the rest of the configuration must remain exactly the same.
