Hi,
We have a MSP430F5438A custom board and want to evaluate "CC4000-TC6000GN EM".We are confused with the RF1/RF2 Connector.
Below wiki page mentions two UART (GPS_RX,GPS_TX) ports to be connected to the MSP430.are these two UART ports required for the communication? http://processors.wiki.ti.com/index.php/CC4000_GPS_MSP-EXP430F5529#RF1_.26_RF2_Interface
And the user manual from GNS mentions,for port 18 & 20 "UART Rx Input; duplicates Pin 7, UART Tx Output; duplicates Pin 8”http://www.tc6000.gns-gmbh.com/files/tc6000gn_em1_user_manual_v01.pdf
Please let us know if it is ok if we leave the pins 18,20 open on the RF1/RF2 Connector.
Regards.Paddu
Hello Paddu,
Yes, the UART ports are definitely required for operation. When they say "UART Rx Input; duplicates Pin 7, UART Tx Output; duplicates Pin 8", this is a typo. It should be pins 7 and 9. Thank you for alerting us to this, and I will let GNS know about this discrepancy.
On connector RF1, you can just use pins 7 and 9, and leave 18 and 20 as unconnected.

Hello Aaron,
Thank you.
I understood that on "RF1 Connector" we can leave 18 and 20 as unconnected.
Regarding the "RF2 Connector"the pin "20- GPS PPS OUT" is mentioned as "precision pulse per second. Available only, when 3D fix is available. logic level = 3.3V"Should this pin also be left unconnected?
And regarding the Evaluation software for CC4000-TC6000GN EM + MSP430F5438A,do we have to contact GNS or is it available from TI?
Regards.Paddu.
Paddu,
If you aren't using the 1 pulse per second feature, then you should leave that pin open. The demo software is available from TI and is at: http://www.ti.com/tool/cc4000gpsem
