hi. GPTimer has been added to the simple_peripheral_oad_offchip project. Consumption current
increased to 4 mA. without timer consumption 27 µA
cc2640
tell me how to fix this and reduce consumption?
Hi Alex,
The GPTimer is dependent on the MCU system clock which means your device must be actively running for the timer to work, thus standby modes are disabled. Here are some relevant E2E threads:
https://e2e.ti.com/f/1/t/1125349
https://e2e.ti.com/f/1/t/1097321
You can see inside datasheet Section 5.4 (Power Consumption Summary) how idle/active will require much more power than standby.
Regards,
Ryan

Thank you . means a large current with gpt is this normal? Or can the current be reduced?
this is important to me, I want to get the minimum current for longer battery operation of the device
Please refer to TI Drivers Power Management and use ti.sysbios.knl.Clock instead of GPTimer. This will allow for standby entry and will service the clock function once the timeout expires.
Regards,
Ryan
Thank you.
1. I tried different modes in Power_setDependency(). But the current consumption has not decreased.
2. I use GPTimer in pulse counter mode. Tell me how to do without GPTimer, but I need a pulse counter?
1. Standby mode will be blocked since there is a hardware dependency (GPTimer) which requires active mode
2. You can use GPIO interrupts to count pulses manually, or close the GPTimer when not counting pulses to allow entry into standby and thus lower power
Regards,
Ryan
Thank you.
1. Regarding GPIO, I have pulses with a frequency of 300 kHz. I think that its use will affect the reliability of the execution of the main program code. I'm using TI-RTOS
2. GPTimer - I do not use it all the time, but I turn it on for 100 ms and at this time the current rises to 4 mA
3. I use BLE. How to reduce core current consumption during GPTimer operation?
Given the high frequency of pulses to count, you will need to develop your application to negotiate a compromise between low power consumption and measuring pulses with GPTimer enabled. You appear to already be familiar with enabling low power modes for simple_peripheral.c and you can consult the SWRU393_CC2640_BLE_Software_Developer's_Guide.pdf document from the BLE SDK. Other options include using the Sensor Controller Pulse Counter on considering an external IC which can count pulses.
Regards,
Ryan
Hi Alex,
If you are using CC2640R2F, according to this you can use the sensor controller to count pulses.
