Change/Editing Energia Library TivaC TM4C1294XL

[GinoP 0]

Hello everyone!

I need editing Energia Library for more flexebility. 
For example, the msp430 launchpad only have one UART available if i use Energia. How can i configure other UARTs? I need at least 3 UART  and I know that TivaCTM4C1294XL have 4 UARTs. Also I need an option for add a parity bit for serial communication.

Thank you so much!

Gino

Hi Gino,

try Serial2, Serial3... for the further serial ports (see energia/hardware/tivac/1.0.3/cores/tivac/HardwareSerial.h && .cpp files for details):

extern HardwareSerial Serial;
extern HardwareSerial Serial1;
extern HardwareSerial Serial2;
extern HardwareSerial Serial3;
extern HardwareSerial Serial4;
extern HardwareSerial Serial5;
extern HardwareSerial Serial6;
extern HardwareSerial Serial7;

For parity I have no idea if it works, but in the energia/hardware/tivac/1.0.3/system/driverlib/uart.h && .c files there are some functions handling the parity:

extern void UARTParityModeSet(uint32_t ui32Base, uint32_t ui32Parity);
extern uint32_t UARTParityModeGet(uint32_t ui32Base);

Best regards,

Liviu

Thanks for reply,
How can use it ? 
Sorry but i am new in this thing

As I said, I haven't use them. Have a look in the (4) mentioned files at the comments to the functions.

I suppose you should have something like following in your code:

uint32_t readParity0 =  UARTParityModeGet(UART0_BASE);
// until
uint32_t readParity7 =  UARTParityModeGet(UART7_BASE);

UARTParityModeSet(UART0_BASE, UART_CONFIG_PAR_NONE); //or
UARTParityModeSet(UART0_BASE, UART_CONFIG_PAR_EVEN); //or
UARTParityModeSet(UART0_BASE, UART_CONFIG_PAR_ODD);
