Serial peripheral interface (SPI)
Up to three SPIs are able to communicate up to 12 Mbit/s in slave and master modes in full-
duplex and simplex communication modes. The 3-bit prescaler gives 8 master mode
frequencies and the frame is configurable to 8 bits or 16 bits.
The SPIs can be served by the DMA controller.
HDMI (high-definition multimedia interface) consumer
The STM32F100xx value line embeds a HDMI-CEC controller that provides hardware
support of consumer electronics control (CEC) (Appendix supplement 1 to the HDMI
standard).
This protocol provides high-level control functions between all audiovisual products in an
environment. It is specified to operate at low speeds with minimum processing and memory
overhead.
GPIOs (general-purpose inputs/outputs)
Each of the GPIO pins can be configured by software as output (push-pull or open-drain), as
input (with or without pull-up or pull-down) or as peripheral alternate function. Most of the
GPIO pins are shared with digital or analog alternate functions. All GPIOs are high current-
capable except for analog inputs.
The I/Os alternate function configuration can be locked if needed following a specific
sequence in order to avoid spurious writing to the I/Os registers.
Remap capability
This feature allows the use of a maximum number of peripherals in a given application.
Indeed, alternate functions are available not only on the default pins but also on other
specific pins onto which they are remappable. This has the advantage of making board
design and port usage much more flexible.
For details refer to
remappable alternate functions and the pins onto which they can be remapped. See the
STM32F100xx reference manual for software considerations.
ADC (analog-to-digital converter)
The 12-bit analog to digital converter has up to 16 external channels and performs
conversions in single-shot or scan modes. In scan mode, automatic conversion is performed
on a selected group of analog inputs.
The ADC can be served by the DMA controller.
An analog watchdog feature allows very precise monitoring of the converted voltage of one,
some or all selected channels. An interrupt is generated when the converted voltage is
outside the programmed thresholds.
