Tool/software:
Hi,
I am moving projects from CC1312R and CC1310 to CC1312PSIP. Most of it already working, except for radio communication. I don't know how to control DIO0 and DIO3 outputs.
Currently for CC1312 we are using SDK 4.10.0.78 and 3.40.0.02. For CC1310 4.10.1.01 and 3.20.0.23. The transition to newer SDK is very problematic for us.
Best regards,
Hi Jakub,
As you maybe can see, the DIO0 and DIO3 pins are internally owned by the RF driver on the CC1312PSIP:
Compared to the CC1312R project, there is also a special rfDriverCallbackAntennaSwitching callback:
/*
* ======== Antenna switching ========
*/
/*
* ======== rfDriverCallbackAntennaSwitching ========
* Sets up the antenna switch according to the TX power table PA type.
*
* Truth table:
*
* Path DIO0 DIO3
* ========== ===== =====
* Off 0 0
* STANDARD PA 1 0
* HIGH PA 0 1
*/
void __attribute__((weak)) rfDriverCallbackAntennaSwitching(RF_Handle client, RF_GlobalEvent events, void *arg)
{
if (events & RF_GlobalEventRadioSetup) {
/* Switch off all paths. */
GPIO_write(CONFIG_RF_STANDARD_PA, 0);
GPIO_write(CONFIG_RF_HIGH_PA, 0);
/* Decode the current PA configuration. */
RF_TxPowerTable_PAType paType = (RF_TxPowerTable_PAType)RF_getTxPower(client).paType;
if (paType == RF_TxPowerTable_HighPA) {
/*
* Mux GPIOs to RF Core signals:
* - High PA --> HIGH_PA
* - LNA enable --> STANDARD_PA
*/
GPIO_setConfigAndMux(CONFIG_RF_STANDARD_PA, GPIO_CFG_OUTPUT, IOC_PORT_RFC_GPO0);
GPIO_setConfigAndMux(CONFIG_RF_HIGH_PA, GPIO_CFG_OUTPUT, IOC_PORT_RFC_GPO3);
} else {
/* RF Core active --> 5_DBM */
GPIO_write(CONFIG_RF_STANDARD_PA, 1);
}
}
else if (events & RF_GlobalEventRadioPowerDown) {
/* Switch off all paths. */
GPIO_write(CONFIG_RF_STANDARD_PA, 0);
GPIO_write(CONFIG_RF_HIGH_PA, 0);
/* Reset the IO multiplexer to GPIO functionality */
GPIO_setConfigAndMux(CONFIG_RF_STANDARD_PA, GPIO_CFG_OUTPUT, IOC_PORT_GPIO);
GPIO_setConfigAndMux(CONFIG_RF_HIGH_PA, GPIO_CFG_OUTPUT, IOC_PORT_GPIO);
}
}
and additional temperature compensation settings:
as well as dedicated CPE patch for the PSIP device + overrrides:
My point being, I strongly recommend you to update to the latest SDK if possible.
Regards,
Arthur
