firmware

HI all I want to make one app for iPhone 2.2.* and for version 3.0. Some method in 2.2* is deprecated in 3.0. ( like UITableViewCell setText and setLabel ) Is there any way to check which firmware version is used on iPhone and to set different method to use You will need to use pre-processor directives for the conditional compilation such as __IPHONE_3_0 and build two separate executables. For example: #ifdef __IPHONE_3_0 // code specific to version 3 #else // code specific to version 2 #end If you need to detect the version at run-time you can use [[UIDevice currentDevice] systemVersion]. It

I'm developing a linux-based appliance using an alix 2d13. I've developed a script that takes care of creating an image file, creating the partitions, installing the boot loader (syslinux), the kernel and the initrd and, that takes care to put root filesystem files into the right partition. Configuration files are on tmpfs filesystem and gets created on system startup by a software that reads an XML file that resides on an own partition. I'm looking a way to update the filesystem and i've considered two solutions: the firmware update is a compressed file that could contain kernel, initrd and

Related to: Testing firmware starting a microcontroller simulator/emulator Interpreting assembly code If you are writing code for a microcontroller is there a real difference if you write in assembly or C or some other high level language? If you wrote C code, how would you compile it? Thanks Several comments: 1) Absolutely not assembly unless performance or optimization constraints warrant it. The following metrics go through the roof with assembly: time to code it time to debug it time to test it time to document it time to figure out (1 year later) what it was you were doing when you coded

How can I use c++11 when programming the Arduino? I would be fine using either the Arduino IDE or another environment. I am most interested in the core language improvements, not things that require standard library changes. jose.angel.jimenez As of version 1.6.6 , the Arduino IDE enables c++11 by default. For older versions, read on: It is very easy to change the flags for any element of the toolchain, including the assembler, compiler , linker or archiver. Tested on the Arduino IDE version 1.5.7 (released on July 2014), Locate the platform.txt file, AVR architecture => {install path}
