Other Parts Discussed in Thread: CC2652R7, SYSCONFIG
I am using Launchpad CC2652R7. I want to verify the current consumption of approx. 1uA as per mentioned in data sheet for Standby mode.
After downloading TI-RTOS sample application name- "pinStandby_LP_CC2652R7_tirtos_ccs" I found that it is consuming 0.5mA with the help of energy trace. But after checking using multimeter (by removing jumper at 3V and adding multimeter) it is come around 1uA.
Now as per my application I want to use UARt and SPI. When I add these two peripheral and sending write operation from both and go to sleep for 5 seconds, the current consumption is much higher when in sleep. I am referring "SimpleLink SDK Power Management: MSP432, MSP432E4, CC13xx/CC26xx, and CC32xx User’s Guide" and as per that after UARt write I called following api
/* Stop the receive to go into low power state */
UART_control(uart0, UART_CMD_RXDISABLE, NULL);
Post this it get stuck in UARt write operation.
Need help with this launchpad setup. Please help to provide any sample application or guide on how to achieve 1uA power when in standby mode with SPI and UART? How to configure these peripherals so that system can enter in standby mode once tx/Rx operation is done.
