Hi, I am using 56F827 for my project. I am using SDK for firmware development. My doubts 1. Communication I am transferring data between two units which contains the above processor using SCI. I want to know the difference between the following parameters which we will have to specify to set the data format. SCI_DATAFORMAT_RAW /SCI_DATAFORMAT_EIGHTBITCHARS. I want to transfer a structure to the other side. How should I use read and write function call effectively? Because read command will wait till it receives the total number of bytes. For e.g. Structure Example: Typedef struct x { int l; unsinged char h; } Typedef struct s { struct x jk; int basic; } My code to write above data ioctl( SciFD, SCI_DATAFORMAT_RAW, NULL ); struct s fg; write (SciFD, &fg, sizeof (struct s) * 2); To read : read (SciFD, &fg, sizeof (struct s)); 2. Switch statement: One thing I have observed that nested switch statement [2 level] is not working though the variable shows exact values. Anybody has faced any such problem ever before?
