 The TFT-LCD assembly arrives taped to the printed circuit board (PCB) and connects through a 45-pin FPC connector. The FPC cable carries both the digital display interface and analog touch panel signals. The TFT-LCD assembly arrives taped to the printed circuit board (PCB) and connects through a 45-pin FPC connector.

-  The display interface is a straight-forward 24-bit RGB pixel bus. The support circuitry on-board the FMC-HMI provides backlight intensity control with pulse width modulation.+The display interface is a straight-forward 24-bit RGB pixel bus. The support circuitry on-board the FMC-HMI provides backlight intensity control with pulse width modulation.
  
-  The four analog signals, X+, X-, Y+, Y- comprise the X and Y plate electrodes. To determine the touch coordinates, users must bias the plates and measure the resistive divider formed by the electrically charged resistive plates using an analog-to-digital converter (ADC) count. When operators use the Shanghai Tianma with system boards that have XADC support, they can use the AMS header to digitalize the analog touch panel signals. An on-board analog multiplexer (MUX) switch helps users select the correct panel electrodes for measurement.+The four analog signals, X+, X-, Y+, Y- comprise the X and Y plate electrodes.

 The FMC-HMI uses a Samtec ASP-134604-01 low pin-count male connector as the main connector for digital signals. Everything except for the PCB dimension requirements conforms to the VITA 57.1 specs. The connector supports the full range of 1.8V-3.3V bank supply voltages (VADJ). The FMC-HMI uses a Samtec ASP-134604-01 low pin-count male connector as the main connector for digital signals.

 A female double Pmod connector offers users the option to connect various Pmods to the system board.  Operators can utilize the ADG3308 auto-sensing bidirectional level translator to level shift from 3.3V to VADJ. It is important to note that due to its low drive current this level translation prohibits the use of strong pull resistors (<60kOhm) on data signals A female double Pmod connector offers users the option to connect various Pmods to the system board.  Operators can utilize the ADG3308 auto-sensing bidirectional level translator to level shift from 3.3V to VADJ.
