I need help with a circuit design. I will be using a teensy 3.2 (or LC) as the MCU. I want the design to be done in, or usable by, Eagle. What I need: [login to view URL] (ramp up and down) a DC current of 0 to 100 mA using the teensy ADC output (3.3volts) as the controller . The DC current needs to be pure and flat, no ripple! 2. To Switch the voltages of the current between 10, 15, 20, and 25 volts. (I'm using three 9 volt batteries as the power supply) 3. To read the the current and voltage being used in real time with the teensy. (I'll use the serial monitor to display it) 4. To have the teensy run on the same battery supply. 5. Need the switches to be controlled from 3.3volt teensy pins. I need an eagle schematic of these things/parts to start with - so I can put it into the rest of the circuit I have started... Through hole or SMD. Parts need to be available and in stock from Mouser or Digikey Thanks!

Hi, I have had many years experience in microcontroller design, from concept to production. I have the capacity to design simulate and prototype the circuitry, produce the PCB artwork in Altium or Eagle, and deliver full documentation and if required I can also produce samples. A few questions: You mention ramping of the output current. Does this mean you need a time varing current output? If so what sort of frequencies are you looking for? The specified voltages are the complience voltages, are a a function of the resistive load you will have across the outputs. Providing the switching is no problem but you may wish to consider using a single 9V battery and bootsing the voltages to the specified levels. Happy to chat about the project. Regards and good luck James Harrison-Smith

I have wide experience designing hardware. I work designing FPGA and SoC hardware so we can reduce the size virtually as much as you want, even putting everything in a single chip. From there, I can make the solution that balances best in price-performance-size for you. Do not hesitate to ask me, I am truly passionate about electronics and I will be delighted with just discussing the feasibility and different possibilities for your project. Hoping to hear from you soon, Borja

Confirm the following you require two outputs from the system - one voltage source and one current source, do you have the block diagram of the system. 1. You need to control the current source with a DAC output. 2. Please confirm the 2nd point, you need to source different output - 3. The current and voltage need to be scaled to what voltage? - what is the ADC reference internal or supply. 4. Do you require LDO or DC-DC converter for the controller supply. 5. what is the end application or use case so that I can understand the system requirement very well 6. what can be the BOM cost of the system is it going to be single quantity or are you going to mass manufacture the system.
