Kinetis K40 and SLCD
« on: July 22, 2011, 04:19:21 PM »
Hi All

Please note that the Kinetis K40 (Tower kit and KWIKSTIK) are supported in the latest Kinetis development version.

Since the K40 is intended for low power devices including segment LCDs (integrated SLCD controller) the next package will contain a new SLCD simulator too. This will be available shortly (watch the SW thread) but in the meantime a user's guide has been prepared here: http://www.uTasker.com/docs/uTasker/uTasker_SLCD.pdf

In addition a new video showing it in operation can be viewed at: http://www.youtube.com/watch?v=nm2DmZv1rj8

Note that it is very simple to design custom LCD modules based on simulation script files, which will allow these to be tested and software for them to be completed before they are physically available.

Regards

Mark

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 method 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 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.
