Posted on September 28, 2017 at 15:11Hi all,
I am currently utilizing the STM32F429 in a project. In order to display information, I am using a QVGA (320x240p) TFT display with an ILI9431 display controller.
However, I am a little afraid of EMI emissions when it comes down to my display, as the pulses of CLK, HYSNC, VSYNC as the slew rate is very high.
Form other controllers I know that some manufacturers offer a parameter called drive strength that allows to reduce the slew rate (thus improving emissions). Does ST feature someting similar? Any ideas how to solve this issue (except for ferrite beads in signal lines?)
Thank you,
Best regards.
