Platform Status Notes
The eLua peripheral modules attempt to provide similar functionality on all platforms for which they are implemented, however some module function varies between platforms. Some known inconsistencies are listed below.
-
STM32: Only timer 2 is supported for clocked conversions.
-
STR9: Clocked conversions are not supported by hardware.
-
LPC17xx: Only timer 1 is supported for clocked conversions.
-
LPC24xx: Only timer 1 is supported for clocked conversions.
