megastim question #3

Postby thedude » Mon Feb 05, 2018 8:03 pm

hello everybody! question with regard to megastim v2.2 "should i see any LEDs light up when powered up but NOT connected to MSII" i was able to successfully program the daughter board and the gauge panel on tuner studio is NOT greyed out so everything looks good but no LEDs on the megastim. the MSII im working is not fully assembled. for example i have completed the third stage (clock circuit construction and testing) does the MegaSquirtII have to be fully assembled for the LEDs to come on megastim?

The LEDs get both their power (5V) and ground from MS. Basically, the Stim just feeds 12v into MS, but is powered by the MS 5v supply.
