MSP-CAPT-FR2633: CapTIvate MCU Development Kit source code and uart configuration

Pedro Peixoto51

Part Number: MSP-CAPT-FR2633

I'm exploring the MSP CapTIvate MCU Development Kit and I want to use an alternative method of communicating with the PC, wirelessly. When exploring the code generated after configuring my sensor layout, I verified that the code for use of the microcontroller peripherals is compiled in a library (driverlib) and I can't find the source code. So I question if this code is open, or if it is possible to get the configurations of the peripherals namely the uart. I also checked the uart.h file but the specified parameters do not allow me to extract the necessary settings to establish a communication.
Thank you for your help

Hello Pedro,

Are you asking how to find the source code behind the DriverLib library functions?

yes, but also some guide to use it. Some parameters are not clear what they mean.

Thanks for your reply. I'd recommend reviewing the MSP430 Driver Library MSP430FR2xx_4xx API Guide and the MSP430 Driver Library MSP430FR2xx_4xx Users Guide. You should be able to find details about the modules/parameters in question.

Hopefully these help.

James

Hello

On MSP CapTIvate MCU Development Kit which baud rate is used on uart to send the data ?

i can comunicate using 256k baud rate, but that don't make sence with this configuration on uart_configuration.h:

#define UART__PRESCALER                                                     (0x08)
#define UART__FIRST_STAGE_MOD                                             (0x00)
#define UART__SECOND_STAGE_MOD                                             (0x00)

On this site i can only calculate the parameters not the baud rate:

Hello Pedro,

The default baud rate is 250k baud. You may find the following thread helpful.

Hello James

Helps a lot, thanks. I have one more question, sorry first time programing u TI.

I receive a lot of data with info sensors and elements state on uart interface, but i can´t understand that data.

Is there any guide with the formatting of the frames? I tried to see through the code but part of the functions that make up the frame are encoded in the rom and I can not see the code. Without it, I get a lot of data but I do not know what the variables are.

Thanks for your help

Hello Pedro,

I'm glad you found it helpful. The code generated by the CapTIvate Design Center assumes that you'll be using the Development Kit with the GUI. Thus, it sends a LOT of data to the PC which enables the features of the Design Center to be utilized. For an application where you want to alert a host processor that a button was pushed, you don't need that much data. So, you'll want to use call-back functions to access sensor data. This is discussed in the CapTIvate Technology Guide. See the Protocol Layer section in the Communication module (found here) for packet structure.

You may find the discussion in the following thread interesting.

James
