Why not control spi nrf_drv_spi_transfer ?

[kevin.ko]

Hello

Nordic Team.

I controling nrf spi.

testing for example nrfSDK14.0.0\example\peripheral\spi\pca10040\blank\arm5_no_packs\spi_pca10040

But i have problem. difference project spi is not working.

drv_max30003.c => max30003_initchip => MAX30003_Reg_Write

Problem here ==> MAX30003_Reg_Write(SW_RST,0x000000);

but source change board is working ==>//MAX30003_Reg_Write(SW_RST,0x000000);

And i have 1 more another question. cccd_handle number difference... not solved question. plz help me.

Kevin, your questions are basically asking for understanding and debugging your complex custom projects. This typically takes hours or rather days of someone's life and I doubt anyone would do it for you just from pure altruism. These are not usual support requests with simple isolated problems. Either learn how to get your problems under control and ask in simplified way so someone can try to answer or give you a hint or hire some consultant who could sit with you for days and weeks, review your projects and help you with all the issues. I'm really not surprised that such questions are left unanswered and that Nordic team cannot spend their time on this. (and no, this isn't sales pitch trying to get hired as a consultant;)

[kevin.ko]

Well ... I understood what you said.

I'm not asking you to fix it, but trying to get a hint of it.

For example, I want answers when controlling SPI

1. Try Timer control.
2. Try Task control.
3. more...?

Obviously, this is something I am developing, and the Nordic Team seems to have undergone a lot of different situations, so I wanted to get help from Spi handling.

It is good to look for and study in project development, but if there is a better way to save time, get a hint from the people you first developed. I asked about notifications in SPI Handling, bluetooth service, but did not ask me to fix everything.

Thanks,

Bestregards,

1. Since nothing gets printed on your serial terminal I bet your code has asserted and ended up in an error handler or hard fault. Have you tried to debug your code and gone through it line by line and checked the return values of for example nrf_drv_spi_transfer()? Here is a short guide to debugging and return codes: devzone.nordicsemi.com/.../

2. The code you have posted at the top prints "SPI example" in one of the first lines and doesn't contain any BLE stuff at all. Your screenshot of TeraTerm on the other hand, prints completely different messages with reference to BLE. This leads me to believe that you have two different applications? I'm very reluctant to help you debug one application based on the output of another.
