Dear Friends,
We have a custom SPI Device (It contains ADS1602 Analog to Digital Converter). We would like to interface (or connect) this SPI device to C6748 processor of our OMAP L138 LCDK. To achieve this goal, we will use McBSP (Multichannel Buffered Serial Port). Our final goal is to transfer and receive data from this SPI Device to our OMAP L138 LCDK, and store the received data as an array of data. We are using the MCBSP example code in OMAPL138 package ,(pdk_OMAPL138_1_01_00_02\packages\ti\drv\mcbsp\example), as our starting point. As mentioned in Table.2 of (www.ti.com/.../spru580g.pdf), McBSP has the following interface pins.
My Question:
1. Which pin on the Extension of OMAP L138 LCDK is connected to the DR (received serial data), DX (Transmitted serial data) of the McBSP Peripheral?
2. I've already checked the OMAP-L138 LC DEV KIT VER A7E (OMAP L138 LCDK schematics), but it seems to me that non of J15 and J14 extensions of OMAP L138 LCDK have a designated pin which connects to McBSP. Perhaps, should we use the SPI pins such as J15.21 and J15.23?
Thank you :)
