I'm working with the SimpleBLEPeripheral program.
I've replaced the CC2540DB drivers with the CC2541ST drivers, since I needed to use a sensor.
I noticed that the hal_sleep.c is different between both directories.
In CC2541ST, DCDC_SBIT is set to 0 before going to sleep and to 1 when waking up.
On CC2540EB, going to sleep doesn't affect the DCDC_SBIT, but the SimpleBLEPeripheral_Init function calls:
// Enable stack to toggle bypass control on TPS62730 (DC/DC converter)
HCI_EXT_MapPmIoPortCmd( HCI_EXT_PM_IO_PORT_P0, HCI_EXT_PM_IO_PORT_PIN7);
(if DC_DC_P0_7 is defined).
Is there a major difference between toggling the control on the DC/DC from the stack vs from the program?
Is there any danger in changing the DC/DC that supplies power to the processor - while the processor executes code?
The documentation of HCI_EXT_MapPmIoPortCmd specifically states "This command should be used with extreme care"...
