Hi, I'm building my own MAME-Arcade-Cabinet from scratch, therefore I built a joystick interface with a microcontroller that is also equipped with a USART. The Interface and the microcode is working and sending bytes with 9600 Baud (8N1). The Plans and Code and all that stuff will be released when all is working as a Open-Project. At the moment I'm trying to write a joystick kernel module like the warrior.c or stinger.c which can be found in /usr/src/linux/drivers/input/joystick/ (these are serial joysticks, too) The Linux Kernel Module Programming Guide at http://www.dirac.org/linux/writing/lkmpg/2.6/lkmpg-2.6.0.html was a good start, also in "How to compile a module _outside_ the kerneltree". To get started with the module, I first want it to dump all incoming bytes from the Linux-uart with printk to a terminal. So I will be able to evaluate more easy and can do the input events like the other joystick modules do. (this is what I have understood when I red the other serial joystick driver) The Problem I have, is that I do not know where and how to set the Baudrate, Parity, Bitlength and Stopbit - and how to catch the serial interrupt and how to get the received bytes and where and how it blocks /dev/ttyS0 for other use. I guess it is done by serio, but form ./include/linux/serio.h I didn't get cute at all. This really confuses me at all. It would be great if anybody out there would be willing to help me? best regards honschu -- Kernelnewbies: Help each other learn about the Linux kernel.
