K40 Segment LCD - demo and simulation

[mjbcswitzerland]

Hi All

As mentioned in the thread https://community.freescale.com/thread/77616, the uTasker project now supports the K40. Since these devices are targeted at low power applications where segment LCDs are used (integrated SLCD controller) it was felt important to be able to accelerate developments of such projects by adding an SLCD simulator.

This can now be seen in the follow short video: http://www.youtube.com/watch?v=nm2DmZv1rj8

The video references the user's guide to using the SLCD simulator as well as configuring user defined script files to add any further LCD types, including user-defined ones [this allows users to design their own custom LCDs and complete software development with them before the modules are actually available in hardware] - this document is available at: http://www.utasker.com/docs/uTasker/uTasker_SLCD.pdf

Hi All

Note that I have added K40 serial boot loaders (for TWR and KWIKSTIK) with USB-MSD loader support on the SW/Live demos page [http://www.utasker.com/SW_Demos.html] . To make the application that is included a little more interested it performs a clock display function on its respective SLCD (TWR board in 12 hour mode with AM/PM indication and KWIKSTIK in 24 hour mode).

The application uses the internal RTC via a second RTC interrupt (so that I could get to know the RTC as well as experiment with methods of controlling fonts on the LCDs). The applications were developed in the simulator. It took a bit of time to set up fonts and a simple algorithm to set these on the Kwikstik's dot-matrix type display but worked first time on the HW too.

I also added K40 executibles (on the same page - search for E_KINETIS toward the bottom of the page) which don't require any installation on a PC but allow these applications to be run simulated. They show the SLCD and the clock (always starting from 0:00:00) and are particularly interesting because the user can also modify the script files in the SLCD directory to experiment with modifications of the LCD as described in the SLCD document http://www.utasker.com/docs/uTasker/uTasker_SLCD.pdf.
