I want to make a bms home system with 8051.But i don't know wich microcontrollers to use.To be specific i need a: 1 microcontroller that can communicate with wifi because i want to control the entire system via my pc b:unknown number of microcontrollers which they were connect with the wifi microcontroller.Also in these microcontrollers will connect the d/a and a/d converters for the sensors.
*For this project will i need any other chips except controllers,converters and the "typical" max232, etc...? *To make the network between all the controllers which protocol do you recommend?will i need specific controllers to make the netwrok?
plz help.... Thanx
Being heavyweight means that a Wifi solution may require very thick manuals to make use of - and some of that information may require that you sign non-disclosure agreements or similar, and in some situations they may expect that you buy a expensive development kit to get the documentation.
Other solutions may allow you do step into an electronics shop and buy two cheap radio modules with RS232 interfaces and a one-page paper showing how to power the units.
