rambo-uploader's Issues

Connection timeouts

Currently we do not use timeouts for serial connection. This leaves the server to hang.

Code Modularity

Currently there are many lines like controller.write("W3H") in the code base. Making a controller class (and the code more OO in general) would clean this up.

Command Line Arguments

Changing the python file when ports enumerate differently is inefficient. Adding parameters for final hex file upload location would make it easier to deliver pre-flashed RAMBos to vendors. Should probably use the python argparse module for this.

Mosfet verification before stepper test

We currently use one of the target mosfet outputs to trigger the stepper recording on the controller. If the mosfets are not working the recording will not initiate and the test server will hang.

1.2 VCC test point

On RAMBo 1.2 there is no pin to verify the SMPS output voltage. There is a via with mask removed near the SMPS IC output capacitors that may be used as a test point.

Board fails and server doesn't say why

When we fail a board from a time out condition we do not display any test results that might hint to the cause. An example is a MOSFET not functioning that we use as a trigger in stepper monitoring. This will lead to the stepper monitoring sequence timing out, reporting "board fail" without the prior results.

Stepper test fails when starting on flag transition

We noticed that when the stepper flag is close to a transition state on start the test will fail. It is possible the debounce setting might be too high in firmware and not catching the transition.

This is a bug, but we will wait until we improve the flag design. Current resolution is to rotate the flag into the middle of a transition.

Reset switch

Should we be testing if the reset switch functions?

Missing controller hardware files

I made a mention of this in pull request #9, but since it got merged without receiving an answer, I'm opening a new issue for this question specifically.
Is it possible for you to upload the hardware files for the controller JIG and instructions on how you are doing your tests ? That would make this repository a bit more useful if the actual JIG can be manufactured.
Thank you.
