I want to develop an industrial board with Cortex-M7 board and i selected Atmel because of Atmel Studio looks very nice for coding. I developed some projects with Arduino. My questions :
ATSAME70Q21 has 114 I/O . Can i use all of these I/O as GPIO?
If answer of first question is "yes" then all of thee GPIO will be interrupted IO?
- I want to buy "SAM E70 Xplained Evaluation Kit" to start Atmel Studio development case. Description of this kit says that kit includes information about to built custom board. My biggest problem is building custom board which i can use all power of this MCU. So i should trust to this evaluation kit or somebody has any advice for building such board?
I read some informations about GPIO pin speed(operating frequency). These pins work at same operating frequency as with MCU speed at some MCUs and slower at some other MCUs. I couldn't see any information for Atmel cortex-M7 MCUs. Is it very important property? What about this property at ATSAME70Q21?
Building a custom board for ATSAME70Q21 is the most difficult step for me. I don't know how should i start. So especially i wait a solution for it.
Tthanks in advance.
