Connect The S5U13781R00C100 With The Stm32 F4-Discovery - Epson S5U13781R00C100 Demonstration Manual

3.1.3 Connect the S5U13781R00C100 with the STM32 F4-Discovery

A connection example for the S5U13781R00C100 reference board and the STM32 F4-Discovery via SPI
is shown in Figure 3-2, Connection Example for STM32 F4-Discovery (via SPI).
If noise on the SPI signal causes problems, place a resistor of several hundred ohms between the
S5U13781R00C100 and STM 32 F4-Discovery SPI port for the purpose of noise damping.
