I am trying to do serial communication in ATMEGA32 and I have a question: In asynchronous serial communication both UBRRH and UCSRC registers have same location. I don't know which conditions that location will act as UBRRH and for which conditions, it will act as UCSRC . I need different values for each register according to the work assigned to those registers In the datasheet, they have mentioned the use of URSEL bit for selection betweem two registers but somehow I am not getting that. The answer is: Yes, the URSEL bit. According to the datasheet: When doing a write access of this I/O

I'm trying to connect to an embedded device through ssh . However, when trying to connect, I always get a connection refused message even when I try changing the port number. I've tried everything to resolve this issue, from changing the file in /etc/ssh/ to accept the specific port number, to sudo iptables -A INPUT -p tcp --dport ssh -j ACCEPT . After reading some comments, it came to me that maybe one of the problems is that I don't have ssh installed on my embedded device. So, how do I infact install ssh on an embedded device? I'm working with a FOX G20 V board with an ATMEL AT91SAM9G20. I

I'm working on a developing board that has a 32-bit ARM based microntroller on it (namely the board is Atmel SAM D21J18A). I'm still at the learning phase and I have a lot to go, but I'm really into embedded systems. I have some background in C. However, it's obviously not enough. I was looking at the codes of an example project by Atmel, and I didn't really get some parts of it. Here is one of them: #define PORT ((Port *)0x41004400UL) /**< \brief (PORT) APB Base Address */ Port is defined as: typedef struct { PortGroup Group[2]; /**< \brief Offset: 0x00 PortGroup groups [GROUPS] */ } Port;
