laforge has uploaded this change for review. ( https://gerrit.osmocom.org/c/simtrace2/+/27387 ) Change subject: simtrace: Enable VCC detection via ADC (voltage dependent) ...................................................................... simtrace: Enable VCC detection via ADC (voltage dependent) SIMtrace should reject any card activation at 1.8V as it is a 3[.3]V device without level shifters. For this, we must include the ADC in determining the VCC voltage.
