+# ulisp-esp32
+
+A version of the Lisp programming language for ESP32-based boards.
+
+For more information see http://www.ulisp.com/show?21T5
+
+Patches from original:
+
+* Deleted all code not for ESP32 specifically (shorter and easier to maintain)
+* Run-from-SD on startup
+* Different printgcs message
+* Used actual name instead of `stringNNN` in lookup table
+* Goheeca and Max-Gerd Retzlaff's error-handling code (https://github.com/Goheeca/redbear_duo-uLisp/commit/4894c13 and http://forum.ulisp.com/t/error-handling-in-ulisp/691/7), but replaced `sp_error` with `fn_throw` (`sp_error` caused a segfault)
+* Dave Astels' macro, intern, and generic :keyword support (http://forum.ulisp.com/t/ive-added-a-few-things-that-might-be-interesting/456)
+
+New custom functions:
+
+* battery:voltage, battery:percentage, battery:change-rate (reading from the MAX17048 on a SparkFun Thing Plus C)
