Tool/software: TI-RTOS
Hello team,
one of my customers came up with the following question:
we’re using CC1310 with the TI-RTOS (Simple Link 1.40) and wondering about the Ringbuffer-Size in the UART.
The example we use is based on the CC1310DK_7XD.c .
There is a UART-Config type
const UART_Config UART_config[UARTCOUNT] = {
{
.fxnTablePtr = &UARTCC26XX_fxnTable,
.object = &uartCC26XXObjects[UART0],
.hwAttrs = &uartCC26XXHWAttrs[UART0]
},
};
that is used to configure the UART. It uses the type
const UARTCC26XX_HWAttrsV2 uartCC26XXHWAttrs[AMB8826_UARTCOUNT] = {
{
.baseAddr = UART0_BASE,
.powerMngrId = PowerCC26XX_PERIPH_UART0,
.intNum = INT_UART0_COMB,
.intPriority = ~0,
.swiPriority = 0,
.txPin = PIN_UART_TX,
.rxPin = PIN_UART_RX,
.ctsPin = PIN_UNASSIGNED,
.rtsPin = PIN_UNASSIGNED
}
};
Usually, the type UARTCC26XX_HWAttrsV2 has the additional fields .ringBufPtr and .ringBufSize , which are initialized in the CC1310_LAUNCHXL.c but not in the CC1310DK_7XD.c
const UARTCC26XX_HWAttrsV2 uartCC26XXHWAttrs[AMB8826_UARTCOUNT] = {
{
.baseAddr = UART0_BASE,
.powerMngrId = PowerCC26XX_PERIPH_UART0,
.intNum = INT_UART0_COMB,
.intPriority = ~0,
.swiPriority = 0,
.txPin = PIN_UART_TX,
.rxPin = PIN_UART_RX,
.ctsPin = PIN_UNASSIGNED,
.rtsPin = PIN_UNASSIGNED,
.ringBufPtr = uartCC26XXRingBuffer,
.ringBufSize = UART_BUFFER_SIZE
}
};
We are wondering now, how the ring buffer and its size is defined in case of CC1310DK_7XD.c?
Debugging says that ringBufPtr and ringBufSize are Null, but I cannot believe this.
In the TI-RTOS, I cannot find any default setting for this buffer.
Thank you very much and kind regards,
Felix
