Hardware Design

Over time, the TFT Graphic Library development board has gone through several revisions to support expanded functionality and additional devices. The latest revision enables testing of both hardware and software SPI modes, as well as full or partial software and hardware parallel interfaces for both 8-bit and 16-bit PIC microcontrollers.

Earlier versions of the development board relied on the SD card slot built into the TFT module, which limited SD card support to modules that included one. Many modern low-cost, small-format TFT modules no longer provide an onboard SD card slot, making this approach restrictive. To address this limitation, an external SD card connector has been added to the current development board.

Another important addition is an 8-pin connector, which follows a common pinout used by many small, low-cost TFT modules currently available on the market. This improves compatibility and flexibility when working with different displays.

This schematic can be used as a reference and starting point for future experimentation and development with TFT displays.
