Hii all, i am developing the driver background for an qtopia application running on my DVEVM (dm355). My second embedded processor like TMS430 or any equvalent processor will make all the required analog circuit and time-sensitive jobs and will communicate wiht my DM355 via uart or i2c in the device organization. This application doesn't have any standart keyboard only have matrix type organized buttons and second mcu will read the pressed button information and send to DM355 via a serial protocol and inerface. Simultaneously, may be come some information from the second processor which is not about keyborad or any character input device. So a kernel modue must analyse the information each time it comes.
The problem is that i dont know the best way for perform that. The possiblities in my head are not much and i am confised a little; 1- Writing a kernel module which will analyse the all data coming to UART and for a sanal keyboard than has node such as /dev/ttySX (i know qtopia has support for tty keyboard drivers). But now one more emulation of concole is required for command enterance to linux. 2- Same as the first item but implemented on i2c bus. 3- A way for reading serial or i2c line from user-space directly and there no need for driver. 4- The way that i wiss you tell me which is more efficent or easy. As a summary i need thw best way for creating a standard character input driver from a nonstandard input device in linux. I am sure there is some fault in my opinions above please please correct me at least. If you done it before please just say the best way. I will do my best for researcing and performing it. Thank for reading and valuable help.
