Does your MCU have LCD interface (SLCD) ? If yes, here's something which could enlight you in the beginning:</P><P></P><P>I have found one presentation to this topic:</P><P><A href="http://www.kinetis.pl/sites/default/files/HandsOn%20Part-1%20-%20MQX%20SLCD%20example.pdf" title="http://www.kinetis.pl/sites/default/files/HandsOn%20Part-1%20-%20MQX%20SLCD%20example.pdf">http://www.kinetis.pl/sites/default/files/HandsOn%20Part-1%20-%20MQX%20SLCD%20example.pdf</A></P><P></P><P>There's LCD driver in MQX for few MCU, like kwikstik contains LCD monochromatic display. In case there's no SLCD in your MCU, you might communicate with LCD through I2C/SPI. MQX provides both drivers.</P><P></P><P>Regards,</P><P>c0170</P></BODY></HTML> Tue, 07 May 2013 06:00:55 GMT https://community.nxp.com/t5/MQX-Software-Solutions/Driver-for-parallel-device/m-p/226500#M6129 c0170 2013-05-07T06:00:55Z Re: Driver for parallel device https://community.nxp.com/t5/MQX-Software-Solutions/Driver-for-parallel-device/m-p/226501#M6130 <HTML><HEAD></HEAD><BODY><P>Hello c0170,</P><P>&nbsp;&nbsp; I'm using a kinetis K60 and K10.</P><P>SLCD module is not available and the HW force me to implement a parallel solution.
