How to Build LED 5X21 MATRIX

[gain]

Hello ,

I want to display "hello" or some data on 5x21 led matrix 

i am using nrf52832 board .

please provide any example code or solution 

Thank you.

There is nowhere near enough info to answer your question!

Describe how the matrix is wired, and how it is to the nRF52832.

Post a schematic.

What board?

Post a link.

To illustrate what, exactly?

How is this fundamentally different from any of the other hordes of LED Matrix project on the interwebs?

What have you tried?

Where are you stuck?

I am new to NORDIC ,

I am stuck at finding the HT1632 header file to include SPIM0 

I want to display a string in 5x21led matrix through HT1632 Led Matrix

where do i find header file of HT1632 LED drive

kindly Provide Solution

We do not have any support for the Holtek HT1632, I suggest you direct your inquiry to Holtek.

Do you have any experience with any other microcontroller(s) ?

The only thing that's specific to Nordic is is how to use the SPI hardware peripheral.

All the hardware peripheral documentation is here;

https://infocenter.nordicsemi.com/topic/com.nordic.infocenter.sdk5.v15.3.0/nrf52832_drivers.html

Specifically, the SPIM:

Hardware peripheral examples are here:

infocenter.nordicsemi.com/.../examples_hw_peripheral_devices.html

With that, you can refer to the Holtek HT1632 documentation, and work from there

• Holtek
• Internet Search Engine; eg, Google
• A search on GitHub

I take  your suggestion, do you have any LED driver IC Library files supported by nRF52DK
