 I want to display &amp;quot;hello&amp;quot; or some data on 5x21 led matrix 
 i am using nrf52832 board . 
 please provide any example code or solution

&lt;p&gt;Do you have any experience with any other microcontroller(s) ?&lt;/p&gt;
&lt;p&gt;The only thing that&amp;#39;s specific to Nordic is is how to use the SPI hardware peripheral.&lt;/p&gt;
&lt;p&gt;All the hardware peripheral documentation is here;&lt;/p&gt;
&lt;p&gt;&lt;a href="https://infocenter.nordicsemi.com/topic/com.nordic.infocenter.sdk5.v15.3.0/nrf52832_drivers.html"&gt;https://infocenter.nordicsemi.com/topic/com.nordic.infocenter.sdk5.v15.3.0/nrf52832_drivers.html&lt;/a&gt;&lt;/p&gt;
&lt;p&gt;Specifically, the SPIM:&lt;/p&gt;
&lt;p&gt;&lt;a href="https://infocenter.nordicsemi.com/topic/com.nordic.infocenter.sdk5.v15.3.0/group__nrf__spim.html"&gt;https://infocenter.nordicsemi.com/topic/com.nordic.infocenter.sdk5.v15.3.0/group__nrf__spim.html&lt;/a&gt;&lt;/p&gt;
&lt;p&gt;Hardware peripheral&amp;nbsp;examples are here:&lt;/p&gt;
&lt;p&gt;&lt;a href="https://infocenter.nordicsemi.com/topic/com.nordic.infocenter.sdk5.v15.3.0/examples_hw_peripheral_devices.html"&gt;infocenter.nordicsemi.com/.../examples_hw_peripheral_devices.html&lt;/a&gt;&lt;/p&gt;
&lt;p&gt;With that, you can refer to the&amp;nbsp;&lt;span&gt;Holtek HT1632 &lt;strong&gt;documentation&lt;/strong&gt;, and work from there&lt;/span&gt;&lt;/p&gt;
&lt;p&gt;&lt;span&gt;&lt;/span&gt;&lt;/p&gt;

&lt;ul&gt;
&lt;li&gt;Holtek&lt;/li&gt;
&lt;li&gt;Internet Search Engine; eg, Google&lt;/li&gt;
&lt;li&gt;A search on GitHub&lt;/li&gt;

&lt;p&gt;I am stuck at finding the HT1632 header file to include SPIM0&amp;nbsp;&lt;/p&gt;
&lt;p&gt;I want to display a string in 5x21led matrix through HT1632 Led Matrix&lt;/p&gt;
&lt;p&gt;where do i find header file of HT1632 LED drive&lt;/p&gt;

&lt;p&gt;Describe how the matrix is wired, and how it is&amp;nbsp;to the nRF52832.&lt;/p&gt;
&lt;p&gt;&lt;strong&gt;Post a schematic.&lt;/strong&gt;&lt;/p&gt;

&lt;p&gt;To illustrate what, exactly?&lt;/p&gt;
&lt;p&gt;How is this fundamentally different from any of the other hordes of LED Matrix project on the interwebs?&lt;/p&gt;
