hello !
i am houssam an electrical engineering student, i am new to this forum and new for ARM processore i want to make my own PLC (programable logic controler), and i need a processore for to build this PLC, i find a lot of type of ARM processore (cortex r,m,a...) i dont know which processore that i should use for this application could you help with the type of the ARM and some books or tutorial that i should see.
thank you, and sorry for my english, it's ot my mother thong.
Hi,
to answer your question, I need answers of at least the following questions?
How much performance do you need?
How much power consumption do you assume?
How wide of the price range do you want?
Is the definite execution time mandatory?
How much memory size do you need?
Is it a flash memory, SRAM or DRAM?
What Operation System do you want to use?
Best regards,
Yasuhiko Koumoto.
thank you for your respond
- for the consumption i dont care because there is no battery it's directly plug in power
- for the price i want a cheap one.
- the processor must execute task in real time.
- and i prefer this characteristics
Hi houssamatif,
your necessary requests seem to be equal to them of the Siemens 6ES7214-1BG40-0XB0.
Why don't you choice it?
Or are you intended to make the 6ES7214-1BG40-0XB0 clone with ARM processors?
The requested performance will be too low and I think any ARM core will be applicable, but because FPU is needed, you can choice Cortex-M4F.
Regarding peripheral functions such as timers, you have many candidates of microcontrollers and you will select what you like.
If we consider the BOM costs, I recommend to use the 6ES7214-1BG40-0XB0.
