144 mcu #31

Closed BeerMoneyMotorsports closed 1 year ago

BeerMoneyMotorsports commented 2 years ago

Please make optional files for using a 144 pin mcu. Relatively urgent request.

andreika-git commented 2 years ago

What do you mean by "make optional files? Do we need a new rev.D for NA6?

BeerMoneyMotorsports commented 2 years ago

I need to order NA6 boards with 144 pin mcu. Do you create an alternate Gerbers and BOM? This should not require nee rev as board ID should take care of firmware differences.

rusefillc commented 2 years ago

One revision is one set of schematics and gerber files. If we change MCU that really wounds like new revision.

@BeerMoneyMotorsports why do you care for revision to not change?

andreika-git commented 2 years ago

I propose to do a new revision (rev.D)

BeerMoneyMotorsports commented 2 years ago

My concern is customer interpretation of revision stability. This is my only problem with a new rev already.

If we are just changing the MCU module, to me, that is not a revision change. I feel like it could be defined as rev C 144 and rev C 176

If it requires changes outside the MCU module, then we should absolutely do a rev D

mck1117 commented 2 years ago

every non-bom change should get a letter rev

rusefillc commented 2 years ago

MCU change is a huge change with very wide implications. I hear the user perception concern but we have to go new letter.

BeerMoneyMotorsports commented 2 years ago

Ok, understood. @andreika-git please continue with rev D for 144pin MCU.

andreika-git commented 2 years ago

@BeerMoneyMotorsports Can you please specify the exact LCSC# for the 144-pin MCU?

BeerMoneyMotorsports commented 2 years ago

C19156

BeerMoneyMotorsports commented 2 years ago

The pinouts match and schematics look good. i have reviewed the pin changes for the MCU and only found two which is great.

I think we can move forward.

Note- noted changes are 1G- ign1 I8 to C13 3I- out tach I0 to G12

BeerMoneyMotorsports commented 2 years ago

yaml tested for the pinout differences from 176 to 144. it seems to work as in it will break those particular outputs when changed. I think we are OK to move forward @andreika-git
