How to implement error Correction Codes (BCH) on nrf52840 development kit?

[ash007]

I have to execute some lightweight error correction codes (ideally BCH) to compare and subsequently correct the mismatches between two binary arrays. I am working on the nrf52840 development kit and using contiki-ng as the operating system. I have to ask if it's possible to implement BCH ECC code, something similar to this, BCH Code in C. I have also found the  emLib ECC - Bit Error Correction for Embedded Devices provided by segger, So my question is if I can use it easily. I am not a pro in embedded programming so looking for some easy code implementation suggestions.

Hi,

I don't have any experience with exactly this but I took a super quick look on the code that you've shared and couldn't see any reasons for it to not work on the nRF. However, I have zero experience with contiki-ng. Lets see if someone else on the forum has a better answer

Thanks for your kind help. I was actually curious to know if this code is lightweight in terms of memory and processing overhead. Is there a way to quickly check it? Also, I have found a few more implementations including https://github.com/torvalds/linux/blob/master/lib/bch.c and https://github.com/torvalds/linux/blob/master/drivers/mtd/nand/ecc-sw-bch.c I am wondering which among these is a better choice.
