Display controller
The STM32MP157 provides two display controllers with different interfaces:
a MIPI-DSI host controller with two data lanes
a LCD-TFT display controller provides a 24-bit parallel digital RGB
The parallel 24-bit RGB-interface of LCD-TFT display controller has a special feature on the
emSTAMP-Argon module. All pins 24-bit RGB interface are connected to SMD-pads on the bottom
side of the module (see picture below).
The DSI-interface is connected to the castellated mounting holes on the edge of the module.

Display Serial Interface (DSI)
The MIPI-DSI-Interface of the STM32MP157 supports two data lanes with 1Gbit/s. The DSI controller
supports color mapping of a16, 18 and 24-bit RGB. The pixel clock for the display data can be
generated by an internal PLL. More information about the DSI interface of the STM32P157 system
can be found in chapter 36 “DSI Host” of the Reference manual of STMicroelectronics.
