Newbie level 1
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.
