STMicroelectronics STEVAL-CCM004V2

Overview

STEVAL-CCM004V2 from STMicroelectronics is an evaluation board designed to demonstrate TFT LCD panel control using the STM32F207VG microcontroller's Flexible Static Memory Controller (FSMC) interface, driving a 3.5" QVGA (320×240) RGB TFT-LCD panel at 60 Hz refresh rate with integrated constant-current LED backlight driver and STMPE811 touchscreen controller.

For engineers reviewing the STEVAL-CCM004V2 datasheet, STEVAL-CCM004V2 pinout, STEVAL-CCM004V2 application, or STEVAL-CCM004V2 equivalent, this board supports rapid GUI development via pre-integrated graphic library APIs, real-time camera image streaming validation, and plug-in daughter-board integration with the STM3220G-EVAL base board for extensible feature prototyping.

Technical Context

The board implements direct RGB parallel interface timing via FSMC with 16-bit data bus (LCD_R[7:0], LCD_G[7:0], LCD_B[7:0]), HSYNC/VSNC/DCLK synchronization signals, and dedicated LCD enable (LCD_ENB) and backlight control (PA1_LCD_BACKLIGHT). It uses STM32F207VG (LQFP100) as main controller and STMPE811 (TSSOP24) for 4-wire resistive touchscreen digitization with I²C host interface.

Backlight drive employs STLD41 constant-current LED driver (SO-8EP) delivering up to 1 A at 40 V with PWM dimming input, supporting adjustable current via R16 (8.06 Ω selected for target panel), while the LCD signal path includes 74LX1G08 level-shifting logic for voltage domain compatibility.

FAQ

Does STEVAL-CCM004V2 include the STM3220G-EVAL base board?

No. STEVAL-CCM004V2 is a daughter board only and requires the separate STM3220G-EVAL base board for operation. It connects via the 50-pin CN3 header and relies on the base board for power regulation, USB debug interface, and expansion connectivity.

What LCD panels are supported beyond the included 3.5" QVGA unit?

The board supports other RGB-interface TFT-LCDs with compatible timing (H/V sync, DCLK, DE) and 16-bit data width, provided their voltage levels match the 3.3 V logic domain and backlight current requirements align with the STLD41 driver's 1 A limit and R16 configuration.

Is the graphic library source code provided with the board?

Yes. ST provides the complete firmware package-including the emWin-compatible graphic library APIs, example projects for static display, camera streaming, and touchscreen interaction-as part of the official STM32F2xx Standard Peripheral Library and STM32CubeF2 software suite.

Can the STMPE811 touchscreen controller be replaced with another model?

No. The STMPE811 is hardware-integrated with fixed I²C address (0x41), GPIO interrupt mapping (PG6_TSC_INT), and calibrated resistor network (R1/R2/R9/R10). Replacement would require PCB redesign and firmware adaptation due to pinout, register map, and timing dependencies.
