Other Parts Discussed in Thread: HALCOGEN

hi iam using TMS570LC43X evalution board(MASTER) i want to communicate with (SLAVE)arinc holt board(hi-3593) using spi(SPI3) iam not able to read the date from slave pls help me out any refrence example wil be good iam beginer in tms570.

Hi Srinivasa,

There are no direct examples on SPI but there is a loop back example on MibSPI in help section of HALCoGen

If you want, you can refer that.

Regarding your code, did you get a chance to probe MOSI line, and did you saw any data on that line?

And can you please attach entire project for easy debugging at our side? Try to zip the entire your project and share it.

Thanks & Regards,

Jagadish.

here cant able to send the zip file sir, i probe the mosi line using cro not getting any data

there is no option for attach zip file here

Hi Srinivasa,

click on Insert and then Image/Video/file option

Now click on upload option

After click on upload option, you can route to the zip file path and attach it.

Thanks & Regards,

Jagadish.

SPI_UPDATE.zippls chk sir

TI__Guru 70621 points

Hi Srinivasa,

I found one typo in your code and after correcting that typo the code working fine

Here it should be spiREG3 right but by mistake you given spiREG1, I corrected that one

also, i added one while(1) at the end of main loop

now your code is working fine, and i can see the proper data as shown below

If you want, you can take below modified code:
SPI_UPDATE_New.zip

Note: Just for testing i changed first transfer to 8 bytes instead of 1 you can change it back to 1.

Thanks & Regards,

Jagadish.

Hi Srinivasa,

1. Please make sure you are probing right signals, according to your configuration

V8 -> MISO
V9 -> CLK
V10 -> CS0
W8 -> MOSI

2. And remember we are not sending data continuously and we are sending data only one time after reset. So, try to reset board after connecting CRO.

I didn't go through the slave datasheet, so please make sure you are sending right bytes in right order.

This is my slave datasheet pls help me ,iam sending cmd RESET(OX04),TCR(0X08),AND READ STATUS CMD(0X84) ,BUT NOT GETTING ANY RESPONCE FROM SLAVE

THANKS AND REGARDS
