Tutorial on SDK_CONFIG.h

[kishanjoshi]

Usually if i am making C Program then i just include the library and get on to the code using documentation. this is same case when i am using STM32 , Samd and esp32

but with nrf52832 and nrf52840 this is not the case. i have to configure sdk_config.h why should i have to do this and there is no proper way or documentation regarding which things should be enabled or which will be in conflict why on earth you guys are making programmers life hell.

I want a automation tool or tutorial to properly configure the sdk_config.h and also an template to import it in eclipse

i just really wants to say that nordic has done very bad sdk. i have never seen something weird , over engineered architecture like this.

you should remove sdk_config.h in future release. sdk should be easy to use and we can start coding easily why is so much mess in this sdk. i really wants see what can my nrf52840 chip can do with openthread and i am very unhappy about the situation.

and yes i said you about what things should i enable or disable. i know how to open a file and edit it. but what should i edit after opening a sdk_config.h that is totally undocumented and that makes nrf un-usable.

1. can you tell me what is easydma ? exactly....

2. what is difference between normal spi api and the one which comes with spi easydma support

The Nordic Semiconductor Infocenter contains technical documentation for our current solutions and technologies. 

1. Using Inforcenter's search: EasyDMA is an AHB bus master similar to CPU and is connected to the AHB multilayer interconnect for direct access to Data RAM. EasyDMA is not able to access flash.
2. SPIM with EasyDMA  and SPIS with EasyDMA- where EasyDMA enables direct transfer to/from RAM for both SPI Slave and SPI Master
   1. DevZone has a couple of cases where people have asked similar questions here and here.

ok so is it faster than traditional spi transfer

[Øyvind]

Yes, similar to what you find on e.g. SAMD

[kishanjoshi]

We are planning to move our all products from stm and samd to nordic so we will need more support.

The Nordic DevZone is the best place to get all the support you need. Make sure to include information about:

• What part/development kit you are using
• What version of SDK you are using
• Potential code you are having issues with (Please use Insert --> Insert Code)
• Detailed explanation about the problem
