Part Number: MSP-EXP430F5529
Tool/software: TI-RTOS
Following this question, trying to reduce the current consumption of the MSP430F5529, running TI-RTOS.
After trying several things (see below), I still cannot get the current below ~500 uA. Questions:
- Does using TI-RTOS inherently increases current consumption?
- Assuming no interrupts are issued (I've disabled the system tick), and that the MCU is in LPM3, does MCLK frequency still effects current consumption?
Test procedure:
- I've started with a simple example project (gpiointerrupt_MSP_EXP430F5529LP_TI), and converted it for the MSP-EXP4305529
- Disabled SVM H/L, as done in pmm_ex3_lowCurrentConsumption
- In gpiointerrupt.cfg, disabled the Clock module, and configured LPM3 on Idle (see cfg file below)
