RTOS/CC1310: RF- UART COMMUNICATION

Hi, you say that in ROV task mode is ready. Have you checked if the stackPeak is not exeeded? Have you tried the BIOS->'Scan for errors' to check if the RTOS is in a bad state (e.g. blown stacks, corrupted data because of bad application pointers or buffer overflows, etc.)?

Hello EMRE,
What boards are you using? The project should work as is on CC1350 and CC1310 launchpads with both receiver and transmitter together in the same project. If it is not, can you try replacing the board files with the correct files.

Hi PrashanthS,
I managed to run project.The problem was caused by the program I was using for serial monitoring.When I changed it with coolterm,I managed to control boards .Could you briefly explain why?
Thanks for the help,

Hello EMRE, 

Good to hear that it is now working. I used coolterm for my tests. What serial program were you using when it was not working? Did you have the same serial port setup as coolterm?

Prashanth

Hi PrashanthS,

I was using HTERM for serial .There is no Local echo feature unlike coolterm.
I also want to say that I am using TTL converter for communication and I see the communication led flashing indicating that the information is being transmitted.But board doesnt reply .when I use HTERM.

I am working with a custom board . I managed to communicate boards with this project.There are a few problems I encountered.

1.Boards are very stable when first running.After waiting for a while, when I want to send message it sends message a few moments later .
Could it be because of my boards?

2.When I send data very often the boards are freezes?


PrashanthS,I am very grateful for your help.

Hi PrashanthS,
I have checked SmartRF studio,
1)We made a custom board it has cc1310 and cc1190 when i use hgm ,my custom boards signal level is -30dB.
cc1310 launchpad signal level is -14dB(max) athough there isnt cc1190.How can we increse signal level ?

2)My second question is about uartread .In uartTxTaskFunction we are trying to read data in while loop.If I do it with uartreadcallback, does the system get faster? I try some codes but it is not working completely.

here is the code changes

I have change tasks priority
#define RX_TASK_STACK_SIZE 1024
#define RX_TASK_PRIORITY 1

#define TX_TASK_STACK_SIZE 1024
#define TX_TASK_PRIORITY 4

#define UART_RX_TASK_STACK_SIZE 1024
#define UART_RX_TASK_PRIORITY 2

#define UART_TX_TASK_STACK_SIZE 1024
#define UART_TX_TASK_PRIORITY 3


and uartTxTaskFunction


char input;
uint8_t charIndex=0;
static void readCallback(UART_Handle handle, void *rxBuf, size_t size)
{


//size_t i ;
// Copy bytes from RX buffer to TX buffer
//for(i = 0; i < size; i++)
//txBuf[i] = ((uint8_t*)rxBuf)[i];
//input = ((uint8_t*)rxBuf)[0];
// Echo the bytes received back to transmitter
//UART_write(uart, txBuf, 1);
// Start another read, with size the same as it was during first call to
// UART_read()
/* Skip the line feed that appears after an enter as the first character of new line */
if (input == (char)CHAR_LINEFEED)
charIndex--;


if ((input == (char)CHAR_LINE_END_1) | (input == (char)CHAR_LINE_END_2)) // (charIndex < UART_SERIAL_LINE_SIZE))
{
/* Cancel Rx */
RF_cancelCmd(rfHandle, rfRxCmd, 0);
Semaphore_post(semTxHandle);
/* reset index to zero to point to begining of the line */
charIndex = 0;
}
else
{
/* Store the input character */
//uartTxBuffer[charIndex++] = input;
txPacket[charIndex++] = input;
}

UART_read(uart, &input, 1);
}

static void uartTxTaskFunction(UArg arg0, UArg arg1)
{
/* Open UART if not already open */
if (uart == NULL) {
/* Create a UART with data processing off. */
UART_Params_init(&uartParams);
uartParams.writeDataMode = UART_DATA_BINARY;
uartParams.readMode = UART_MODE_CALLBACK;
uartParams.readDataMode = UART_DATA_BINARY;
uartParams.readCallback = readCallback;
uartParams.readReturnMode = UART_RETURN_FULL;
uartParams.readEcho = UART_ECHO_OFF;
uartParams.baudRate = 115200;
uart = UART_open(Board_UART0, &uartParams);

if (uart == NULL) {
System_abort("Error opening the UART");
}
}

UART_read(uart, &input, 1);

while (1)
{
//UART_read(uart, &input, 1);
}
}

Q: We made a custom board it has cc1310 and cc1190 when i use hgm ,my custom boards signal level is -30dB.
cc1310 launchpad signal level is -14dB(max) athough there isnt cc1190.How can we increse signal level ?

A: Please verify that PA_EN and LNA_EN are set correctly.

I assume the power levels you have measured are conducted?

Hello TER,
I set and verified signals like that

(1=3.3V)
HGM = 1;
LNA = 1;
PA =0 ;

Are these values correct ?

Here is the code part :

PIN_Config pinTable[] =
{
Board_HGM | PIN_GPIO_OUTPUT_EN | PIN_GPIO_HIGH | PIN_PUSHPULL | PIN_DRVSTR_MAX,
Board_LNA_EN | PIN_GPIO_OUTPUT_EN | PIN_GPIO_LOW | PIN_PUSHPULL | PIN_DRVSTR_MAX,
Board_PA_EN | PIN_GPIO_OUTPUT_EN | PIN_GPIO_LOW | PIN_PUSHPULL | PIN_DRVSTR_MAX,

PIN_TERMINATE
};

and I set them in rxTaskFunction like that

PIN_setOutputValue(pinHandle, Board_HGM,1);//high gain
PIN_setOutputValue(pinHandle, Board_PA_EN, 0);
PIN_setOutputValue(pinHandle, Board_LNA_EN, 1);//rx mode
