Kinetis Clicker SPI_0 Problem

[Alessandro Fulignani]

Hi MikroE,

I'm testing the SPI_0 on port(PTC4 5 6 7 ) with yours kinetis clicker.

While i can see the TX data on the SPI, i'm not been able to find a way to read the RX buffer.

I realized a clean uB project where i've selected only the SPI library.

With the oscillscope i can read the TX transmission CLK and MISO/MOSI correctly, but nothing appear on "take"buffer nor the SPI0 rx buffer/s

I did the test on several Kinetis clicker board, but the result it's the same.

P.S.

If i skip the routine "SPI0_Init()" and i initialize directly the registers,the SPI work fine.

Do you have any suggestions?

Thank you,

Alex

Hello,

Can you zip and send me a minimal project which demonstrates your problem?

Kind regards,

Hi Jovana,

Just create a new project and follow the library indications:

' read a word from the SPI bus

dim take, buffer as word

spi0_init()

take = SPI0_Read(buffer)


Thank you,

Alex

HI Jovana,

Do you have any news?

Hello,

I tested SPI0 (PTC5_6_7 ) on Kinetis clicker and it works fine.
I suggest you use SPI0_Init_Advanced function instead of SPI0_Init, because with SPI0_Init you need to use PTD1_3_2.

Kind regards,
Jovana
