+
+You probably need to enable a time driver for your HAL (not in `embassy-time`!). For example with `embassy-stm32`, you might need to enable `time-driver-any`:
+
+[source,toml]
+----
+[dependencies.embassy-stm32]
+version = "0.1.0"
+features = [
+    # ...
+    "time-driver-any", # Add this line!
+    # ...
+]
