STM8L+BC26 dual low power consumption, micro ampere-EEWORLD

Collect

I am working on a project that requires STM8L and BC26. To connect to the server after a long disconnection and send the current status, I need to use the low power consumption of STM8L and BC26.

STM8L has low power consumption, so HALT mode is used here, and RTC wakes up at a specified time.

The first step is to turn off all peripherals, set all pins to output, and output low. Set the pins according to the specific environment, and output high level if necessary. After turning off the peripherals, you need to _DeInit first, and then turn off the peripherals. It is important to clear all interrupt flags when entering halt mode, otherwise the RTC wake-up will not work.

The second step is to set some low power configurations.

After the third step configuration is completed, it will enter low power consumption.

The project needs to use external high-speed clock and BC26 communication, so when entering and exiting halt mode, it is necessary to reinitialize the clock and peripherals in active mode. When low power consumption is required, configure it to low power consumption configuration. In this way, switching configurations back and forth can achieve low power consumption. After testing, the low power consumption current is: 10uA.

Implementing IAP (In Application Programming) on STM8L

1. To download Boot and App to different addresses of FLASH, we need to configure the link script. The default link script of IAR is in the installation directory C:\Program Files (x86)\IAR Systems\Embedded Workbench 7.0\stm8\config. Find the corresponding chip and open it. You can see the following words: ////////
