Silicon Labs / EFM32_SegmentLCD

This is a driver for the segment LCD found on the Silicon Labs EF32 Giant, Leopard and Wonder Gecko platforms. NOTE: This driver will not work with other platforms, because it contains EFM32-specific code.

Information

All examples in this repo are considered EXPERIMENTAL QUALITY, meaning this code has been created as one-off proof-of-concept and is suitable as a demonstration for experimental purposes only. This code will not be regularly maintained by Silicon Labs and there is no guarantee that these projects will work across all environments, SDK versions and hardware.
