For a personnal project, I intend to design a board with a temperature sensor, an MCU and a wireless "connector". I would like to have that board powered by battery. The wireless technology is not yet clear, but I am considering which MCU would be the most adapted?
I was considering the following characteristics:
- easy to place and to program,
- low-power (and probably some sleep mode built in),
- one 6-8 bits ADC,
- Some I²C and/or serial connection,
- one or more digital outputs to, e.g. light some LED.
The precision and speed are not decisive criteria, so proably an 8-bits MCU is perfectly fine.
Semi-conductors companies often provide some comparison tools but those are limited to their own products, like here, SiLabs. But I wanted to know if one/any of you had any experience in that respect, and would be able to recommand some MCU.
As it is a personal project, the compiler should not be too expensive, and ideally free.
Can anyone provide me any insight on that?
