**PLEASE, NO BIDDING BEFORE READING FULL DESCRIPTION**
We require an API for Windows to be developed in ASP.NET, to interact with a board that connects to a computer via USB. The communication with the board is to be accomplished through AT commands.
Some of required functionalities
2 types of commands,
- Functional - related to the operation of inputs and outputs
- Informative - Help List of the commands and the firmware version.
The API must load a config file on the same directory as the parameters:
AT + f n e <CR> <LF>
All commands must first terminate by carriage return <CR> (0x0D) (/ r), optionally new line <LF> (0x0A) (/ n) can be included next
This board has 4 fixed inputs (1 @ 4) and an AUXILIARY (A) that is shared with an output according to the position of a JUMPER. If nothing is connected to that entry, read 1
This board have 5 power outputs (1 @ 4) and an AUXILIARY (which is shared with an input according to the position of a JUMPER) with 4A power management.
IMPORTANT NOTE: The developer select will NOT have access to the actual board. It is the developer job to write the code, and deliver it to us for testing and approval.
Full description of the requirements are in the .PDF attached
Target budget for this job is 150$, we might be able to stretch it to 200$, and should be done within 5 to 7 days.
