STMicroelectronics STEVAL-PCC008V1

Overview

STEVAL-PCC008V1 from STMicroelectronics is a TFT display demonstration board implementing an embedded Ethernet web client system based on the STR91xFAW ARM966E-S™ 16/32-bit Flash MCU with integrated Ethernet MAC and PHY. It displays JPEG images captured from HTTP web servers or IP cameras, features a 2.4" TFT screen, six-button keypad, and microSD card interface for local data handling.

For engineers reviewing the STEVAL-PCC008V1 datasheet, STEVAL-PCC008V1 pinout, STEVAL-PCC008V1 application, or STEVAL-PCC008V1 equivalent, this board serves as a ready-to-run reference for networked image monitoring, JPEG decompression on ARM9, TFT-driven surveillance UIs, and microSD-assisted image buffering in resource-constrained embedded systems.

Technical Context

The board executes pre-programmed HTTP GET requests to fetch JPEG streams from non-SSL web servers or IP cameras, then performs real-time JPEG decompression using firmware running on the STR91xFAW's ARM966E-S core. Image data is rendered directly to the 240×320 RGB TFT via dedicated FSMC interface and DMA-controlled pixel transfer.

It integrates hardware-level Ethernet connectivity (10/100 Mbps), on-board microSD slot supporting FAT16/FAT32 file systems, and a tactile keypad for menu navigation-enabling standalone operation without host PC interaction. Power is managed through discrete LDOs generating 3.3 V and 1.8 V rails for MCU, TFT, and peripherals.

FAQ

Does STEVAL-PCC008V1 support HTTPS or TLS-secured web servers?

No. The pre-programmed firmware only implements HTTP client functionality without SSL/TLS stack or cryptographic acceleration. It connects exclusively to unencrypted HTTP endpoints, making it unsuitable for modern secure web services but functional with legacy IP cameras and basic HTTP image servers.

Can the STR91xFAW firmware be reprogrammed or updated?

Yes. The board provides SWD debug interface and supports firmware updates via ST-LINK/V2 or compatible JTAG/SWD programmers. The STR91xFAW's internal Flash allows full reprogramming of the web client logic, JPEG decoder, and UI layers using Keil MDK or GCC-based toolchains.

What image formats does the board natively decode and display?

Only baseline JPEG (JFIF) format is supported. The onboard firmware includes a lightweight JPEG decompressor optimized for ARM966E-S, outputting RGB565 bitmaps directly to the TFT frame buffer. BMP, PNG, GIF, or progressive JPEG are not handled.

Is the microSD card used for booting or only for data storage?

Exclusively for data storage. The STR91xFAW boots from its internal Flash memory. The microSD card holds sample JPEG images, configuration files, and cached network captures-but plays no role in boot sequence or firmware loading.
