    <description>&lt;HTML&gt;&lt;HEAD&gt;&lt;/HEAD&gt;&lt;BODY&gt;&lt;P&gt;Hello Everyone.&lt;/P&gt;&lt;P&gt;&lt;/P&gt;&lt;P&gt;I have a challenging questions and would love to get feedback.&amp;nbsp; I need to write a UNI/O driver to talk to an EEPROM.&lt;/P&gt;&lt;P&gt;I am running on a K28.&amp;nbsp; I'm trying to run the processor at 4MHz.&amp;nbsp;&amp;nbsp;&lt;/P&gt;&lt;P&gt;&lt;/P&gt;&lt;P&gt;I would need to set up a PIT or FTM timer to fire off every 80µs.&amp;nbsp;&amp;nbsp;&lt;/P&gt;&lt;P&gt;&lt;/P&gt;&lt;P&gt;Now I can change the speed while doing these writes, but I'd like to try and get some feedback on anyone that has done a UNI/O driver before.&lt;/P&gt;&lt;P&gt;&lt;/P&gt;&lt;P&gt;So if you have written a UNI/O driver and want to share, I'm all ears.&lt;/P&gt;&lt;P&gt;&lt;/P&gt;&lt;P&gt;-stv&lt;/P&gt;&lt;/BODY&gt;&lt;/HTML&gt;</description>

      <description>&lt;HTML&gt;&lt;HEAD&gt;&lt;/HEAD&gt;&lt;BODY&gt;&lt;P&gt;Hi Steve Iribarne,&lt;/P&gt;&lt;P&gt;&amp;nbsp;&amp;nbsp;&amp;nbsp; I have searched the website, it seem the UNI/O EEPROM is from the microchip/atmel.&lt;/P&gt;&lt;P&gt;&amp;nbsp;&amp;nbsp;&amp;nbsp; We don't have that driver, but I think you can check it with microchip, they may have the according driver.&lt;/P&gt;&lt;P&gt;&amp;nbsp;&amp;nbsp; On NXP side, if you want to use the k28 pit or the FTM, we will provide the PIT and FTM driver.&lt;/P&gt;&lt;P&gt;&amp;nbsp;&amp;nbsp; You can find it from our SDK package, the SDK you can download it from this link:&lt;/P&gt;&lt;P&gt;&lt;A class="link-titled" href="https://mcuxpresso.nxp.com/en/dashboard?uvid=115179" title="https://mcuxpresso.nxp.com/en/dashboard?uvid=115179"&gt;https://mcuxpresso.nxp.com/en/dashboard?uvid=115179&lt;/A&gt;&amp;nbsp;&lt;/P&gt;&lt;P&gt;&lt;/P&gt;&lt;P&gt;Folder SDK_2.2_FRDM-K28F\boards\frdmk28f\driver_examples&lt;/P&gt;&lt;P&gt;If you want to generate 80us, just use the according driver to configure the according timeout value.&lt;/P&gt;&lt;P&gt;If you want to change the time, it is the same, just change the according timeout value.&lt;/P&gt;&lt;P&gt;Please check our PIT or FTM code at first.&lt;/P&gt;&lt;P&gt;If you still have question about it, please kindly let me know.&lt;/P&gt;&lt;P&gt;&lt;/P&gt;&lt;P&gt;&lt;/P&gt;&lt;P&gt;&lt;BR /&gt;Have a great day,&lt;BR /&gt;Kerry&lt;/P&gt;&lt;P&gt;&lt;/P&gt;&lt;P&gt;-----------------------------------------------------------------------------------------------------------------------&lt;BR /&gt;Note: If this post answers your question, please click the Correct Answer button.
