WebPeripherals API » GPIO & RTC GPIO Edit on GitHub GPIO & RTC GPIO ¶ Overview ¶ The ESP32 chip features 40 physical GPIO pads. Some GPIO pads cannot be used or do not have the corresponding pin on the chip package. For more details, see ESP32 Technical Reference Manual > IO MUX and GPIO Matrix (GPIO, IO_MUX) [ PDF ]. WebJun 8, 2024 · This is the time register from the STMicroelectronics STM32F407’s RTC peripheral. Notice that the tens digits for hours (HT), minutes (MNT), and seconds (ST) are less than 4 bits wide since they don’t have to span the whole range of 0 through 9, some RTCs will save bits by allocating only the number of bits that are absolutely necessary.
