3.16.3

Serial peripheral interface (SPI)

A SPI interface allows to communicate up to 18 Mbits/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 size is configurable from 4 bits to 16 bits.

The features available in SPI1 are showed below in Table 9.

3.16.4

Controller area network (CAN)

The CAN is compliant with specifications 2.0A and B (active) with a bit rate up to 1 Mbit/s. It

can receive and transmit standard frames with 11-bit identifiers as well as extended frames

with 29-bit identifiers. It has three transmit mailboxes, two receive FIFOs with 3 stages and

14 scalable filter banks.

3.17

Infrared transmitter

The STM32F303x6/8 devices provide an infrared transmitter solution. The solution is based

on internal connections between TIM16 and TIM17 as shown in the figure below.

TIM17 is used to provide the carrier frequency and TIM16 provides the main signal to be

sent. The infrared output signal is available on PB9 or PA13.

To generate the infrared remote control signals, TIM16 channel 1 and TIM17 channel 1 must

be properly configured to generate correct waveforms. All standard IR pulse modulation

modes is obtained by programming the two timers of the output compare channels (see

Figure 3).
