Why did Denethor, Lord of Gondor, burn himself to death? But beeing able to use Java for developing drivers can be a benefit in itself by making it more difficult to totally screw up things. #2.2.1.1 Joerg (Homepage) on 2007-01-18 18:36 The language derives much of its syntax from C and C++ but has a simpler object model and fewer low-level facilities.

Once the device sends data back to the driver, the driver may invoke routines in the original calling program. Join them; it only takes a minute: Sign up Is it possible to code a device driver in Java? The same goes for whatever class libraries you use.

A more widespread use might be drivers for USB devices if Java ever gets a decent USB library. a vendor specific handshaking algorithm on top of an OPC layer).

The paper about a JVM on Linux is very bad, and their performance numbers are not convincing - indeed, they test a USB 1.1 network driver, and then show that performance But you can compile Java to native code.

posted 7 years ago Why would you want to? While for a disk or Ethernet driver you need top-notch performance, and while in Linux drivers today are the bottleneck for 10G Ethernet or SSD disks, most drivers don't need that Historically, they are done in a low level language like C and/or assembly. http://forumfamiljar.com/device-driver/device-drivers-programming-c.php Navigation Home Impressum Datenschutzhinweis Disclaimer Favorites Das Archiv Essays Blogroll Tour dates ;) solaristutorials.org < Tapeout of Rock | Personal analog assistant > Device driver in Java Thursday, January 18. 2007

It's very easy, right ? The opinions expressed here are his own, are not necessarily reviewed in advance by anyone but the individual author, and neither Oracle nor any other party necessarily agrees with them. I only interested in ‘open' (handles the driver opening), ‘release' (handles the driver closing), ‘read' (handles data transfer from driver to user application), and ‘write' (handles data transfer from user application

Java is a really good choice here.

Otherwise, ask kernel for our device's major * number * * @return negative value for error, 0 for success */ static int register_driver(void) { int retval = 0; if (simplemem_major != if java language…what API?? In summary, the power of java: It is useful for both business logic as complex interfacing. It needs the Java VM to interpret and JIT the bytecode, and it needs the class library and so on.

The JDDK allows a JavaPOS developer to create, test, package, deploy and manage JavaPOS Device Services without regard to underlying client or server operating systems. Here's my experience with simple character device from Linux Kernel Module Programming Guide.First of all, you need to specify the ‘methods' that your driver wants to handle. I've seen java print at a continuous speed of 100ms/cycle. http://forumfamiljar.com/device-driver/device-drivers-programming-in-c-pdf.php And therefore the idea of creating a committed driver interface for Linux and other UN*Xes is also dead.

You would be able to use the same driver in different operating system without recompilation. It merely has to be able to be linked together with OS code. Otherwise, the GNU make will not be able to run # this Makefile # default: $(MAKE) -C $(KERNELDIR) M=$(PWD) modules endif clean: rm -rf *.o *.ko *.mod.c .*.cmd .tmp_versions Module.markers modules.order can anyone suggest a guide line? "Device Drivers", assuming that you are using the common definition, are code that is loaded directly into the Operating System...

I said possible. ;) See also Device Drivers in User Space, which discusses using the UIO framework to build a user space driver.

Don't underestimate the differences between a rich environment (application-level, with a nice set of runtime library features - that's the strength of Java), and a restricted environment (kernel-level, where you just The memory hit to these drivers and operating systems would be substantial.
