Passcode Lock Screen for iOS

I have designed a small library (with its test project) that lets you implement a passcode lock screen on iOS. The library is compatible with iPod Touch, iPhone and iPad. And it is very easy to use.
EAPasscodeLock* passcodeManager = [[EAPasscodeLock alloc] init];
UIViewController* plViewController = [passcodeManager passcodeViewControllerWithCode:@"1234" cancellable:YES hintText:nil maxRetries:4 delegate:self];
[self presentModalViewController:plViewController animated:NO];

There is a protocol you should implement, with only one obligatory method, that sends messages to the main view.
@protocol EAPasscodeLockProtocol
// Called when the passcode is entered correctly after dismissing the passcode View Controller
// Called when the passcode is entered correctly before dismissing the passcode View Controller
// Called when a passcode entered is incorrect
// Called when the cancel button was pressed and after the passcode View Controller is dismissed
// Called when the passcode was entered incorrectly too many times
Here a few screenshots of the iPad UI

iPhone App for AVR Development

There is an infinite number of AVR website that has configuration wizards for UART, Timers and SPI, but I didn’t find an iPhone application that can do something similar. So I developed an iOS application that lets you setup the AVR SPI easily, email this configuration, and also understand what each bit of the SPI registers does. The application is called AVR ISP and soon it will be available in the App Store. Hopefully the next version (1.1) will have code generation in C and ASM, and not only for the setup, but also including functions for handling the SPI interface.
Here I show some of the screenshots of the app. And as soon as Apple publishes the app in the Store I’ll upload the link.

UPDATED: Apple has approved AVR SPI and now it’s ready for download from the App Store. You can find it by just looking for “AVR SPI” or using this link to iTunes
