Contract - 8051 Firmware I2C Enhancement - Urgent

Peter Fedorow 

Kiosk provider seeking an 8051 assembly language developer to patch firmware to:

* Add two i2c commands:
    1-turn on
    2-turn off


Notes:

1.  Device has pre-existing soft power control.

2.  Device has pre-existing operational I2C interface.

3.  Current firmware is available only as ROM image.

4.  We -possibly- have some C source code for the 8051-based controller, but it is not configured for the product, nor includes past manufacturer provided customizations.  It is probably mostly useful as a reference tool.



Deliverable Requirements

1.  ROM image:
    a.  With new I2C on/off command functionality.
    b.  Upon boot, the device must start in the existing on state.
    c.  All existing functionality must still be operational.
    d.  Provided in the same ROM-able Intel hex format the original firmware image was supplied in.

2.  New functionality in deliverable #1 must pass 100 I2C command off/on test cycles.

3.  Assembly language listing for deliverable #1, with descriptive comments documenting changes.

4.  Deliverables must be provided within 6 business days from when both parties agree to commencement of work.


Available Resources

We can provide for the duration of the work:

* One controller board for development/testing.
  -and-
* One end-product module which uses the controller board.


Work Quotation

Please e-mail:

* Your all-in fixed price for the work.

* Relevant qualifications.

* The option of partial payment mid-way through project requires two strong references.  Otherwise, payment is upon receipt of the required deliverables.
