CCS/CC2652R: How to use UART_readPolling

Hi,

I am not sure when this will come about. However, you can use the register level driverlib APIs to write a polling UART driver.

See code below.

// UART pinmapping
#define EXAMPLE_PIN_UART_RXD IOID_2
#define EXAMPLE_PIN_UART_TXD IOID_3
#define EXAMPLE_PIN_UART_CTS IOID_UNUSED
#define EXAMPLE_PIN_UART_RTS IOID_UNUSED

int UARTinit(void){

PRCMPowerDomainOn(PRCM_DOMAIN_SERIAL);
while(!(PRCMPowerDomainStatus(PRCM_DOMAIN_SERIAL) == PRCM_DOMAIN_POWER_ON))
{ }

//
// Enable the UART clock
//
PRCMPeripheralRunEnable(PRCM_PERIPH_UART0);

//
// Apply clock settings and wait for them to take effect
//
PRCMLoadSet();
while(!PRCMLoadGet())
{ }

//
// Disable UART function
//
UARTDisable(UART0_BASE);

//
// Disable all UART module interrupts
//
UARTIntDisable(UART0_BASE, UART_INT_OE | UART_INT_BE | UART_INT_PE |
UART_INT_FE | UART_INT_RT | UART_INT_TX |
UART_INT_RX | UART_INT_CTS);

//
// Map UART signals to the correct GPIO pins and configure them as
// hardware controlled.
//
IOCPinTypeUart(UART0_BASE,EXAMPLE_PIN_UART_RXD,EXAMPLE_PIN_UART_TXD,
EXAMPLE_PIN_UART_CTS,EXAMPLE_PIN_UART_RTS);

//
// Configure the UART for 115,200, 8-N-1 operation.
// This function uses SysCtrlClockGet() to get the system clock
// frequency. This could be also be a variable or hard coded value
// instead of a function call.
//
UARTConfigSetExpClk(UART0_BASE, GET_MCU_CLOCK, 115200,
(UART_CONFIG_WLEN_8 | UART_CONFIG_STOP_ONE |
UART_CONFIG_PAR_NONE));
//
// Enable UART
//
UARTEnable(UART0_BASE);
}

You can use the following APIs for the communication:

 cThisChar = UARTCharGet(UART0_BASE);

UARTCharPut(UART0_BASE, cThisChar);

Thanks.
