Hey guys! I'm new here, and I hope you guys can help me with something.
I need to select a microcontroller (or would a digital signal processor be better?) for the following:
Planning to incorporate temperature control of a small area (abt 6 cmX 6 cm) with a Peltier element. (Any better ways to cool it to about 25 degrees?) So I need to:
Get a specific value of temperature from a laptop to the microcontroller.
Get the temperature of the platform cooled via a temperature sensor (probably an IC sensor from TI.)
Compare the difference and output a control signal (possibly a PWM) that can be used to increase/decrease the temperature of the area as per the need.
The current waveform output from a photodiode needs to be transferred to the laptop (like a CRO?). Since the current wf is analog, I would guess that this requires an
ADC. Need one with pretty good precision too.
I also need to get
sample values of voltage and current from a solar cell at regular intervels of time. (To get its V-I chara).
While I have interfaced before, I'm still pretty new to this. What MC or DSP should I use? Help please.
