Hi there,

I configured MibSPI3 as master and MibSPI1 as slave

On the Hercules TMS570LC43x Launchpad, I connected SPIclk, SIMO and SOMI pins.

Which pin of the 6 available MibSPI3CS [0..5] do I have to connect and

what configuration (CS_0 ... CS_7) do I have to choose within HalCoGen for the affected MIBSPI-TransferGroup (in TransmitBuffers) accordingly?

I would be very glad about some documentation regarding the CS-pins for the MibSPI's.

Hello Matthias,
In HALCoGen you could specify TG0 to use CS0 and set all other CS pins as GIO (not functional).

In TRM, Section 28 Multi-Buffered Serial Peripheral Interface Module (MibSPI) with Parallel Pin Option (MibSPIP) you could find more info about CS.

Best regards,
Miro

Hi Miro,

thanks for your reply!

If I choose CS_0 for my TransferGroup in HalCoGen, which pin do I have to use therefore?

I do not understand the logic, how the eight CS_0 ..CS_7 map to the six MIBSPINCS[0..5] pins.

On the launchpad, only MIBSPI3NCS[1..3] are available on connector J2

What do you mean by TRM? could you provide a link to this docu, please?

thanks a lot

Matthias

Hello,
Sorry I meant device TRM (Technical Reference Manual ): www.ti.com/.../spnu563a.pdf
