Method for a dual post-code alphanumeric display module

Disclosed is a method for a post-code alphanumeric display module. Benefits include improved error detection.

Description

              The disclosed method is a dual post-code alphanumeric display module. Also known as the Read-Only Electronic Display Eye (REDi), the method is comprised of the following components:

·        Dual 7 segment LED (see Figure 1)

·        One 10x 2 surface-mount (SMT) header (see Figures 2 and 3)

              The dual LED has 18 signal pins (see Figure 4). They are appropriately soldered to the pins of the 10x2 female header. It plugs into a male 10x

 header that is located on a storage adapter. During initial power-on, the board goes through initialization. The display module displays error codes if any errors occur during the initialization process. The codes are displayed as two hexadecimal digits (see Figure 5).

              One REDi module can be utilized on all adapters because the module is pluggable rather than soldered on every circuit board (see Figures 6 and 7).

Advantages

              The disclosed method provides advantages including:

·        Easy to install and use

·        Cost efficient due to reusability

·        Improves the development environment due to the capability to report errors during initialization

·        Saves silicon surface area due to reusability
