Thank you. I went for pin 9 using 2A. P9 is defined as VCCEN for LCD SPI , which is a kind of power enabling, which seems most applicable for the backlight power.
A proposal for USB PMOD connector.
Pin 1: N.C, GPIO, ID (*) or CC1(**)
Pin 2: D-
Pin 3: N.C/GPIO or CC2 (**)
Pin 4: D+
Pin 5: GND
Pin 6: VBUS (5V)
(*) Using a Micro-B connector (OTG ID pin)
(**) Using a Type C USB 2.0 signals
Some SPI LCDs have a PWM Backlight On/OFF/PWM input. I want to create a PMOD compatible LCD board.
Which pin should be most applicable to assign as PWM on a RGB LCD PMOD connector ? Pin 9 VCCEN or P10 PMODEN ? Reference modules: PMOD MTDS, PMODOled
