STM32 power saving: wake up from RTC alarm and Serial – 6
As usual our microcontrollers give a wide range of wake up sources, we already see a timed wake-up, and now we introduce the wake-up via RTC alarm and Serial of our STM32.
Category: UART
A universal asynchronous receiver-transmitter (UART) is a computer hardware device for asynchronous serial communication in which the data format and transmission speeds are configurable.
i2c, SPI and UART compared
I2C, SPI, and UART are protocols that we encounter all the time in this world, but why do we need all these protocols to interconnect external peripherals? Well! The answer is simple because there are many needs to be met, and each protocol has a well-defined scope.
