TIC80 C Language Template

Difference comparing to official template

This template doesn't require wasi-sdk. All your need is clang(C language family frontend for LLVM), lld(wasm-ld from the LLVM project), llvm(llvm-ar tools from the LLVM project) and tic80 packages.

The advantage of not using wasi-sdk is:

• Won't invoke WASI api by mistake, which is not provided by tic80.
• No extra dependencies. Have a minimal libc (modified from wasi-sdk source).

Useage

• Clone this template.
• Modify Makefile, change TARGET_NAME to project name.
• Compile only the wasm part: make clean && make wasm
• Compile and make the cart: make clean && make cart
• Compile and run the cart: make clean && DEBUG=1 make run
• In order to speed up compiling, static linked library is used. clean the static library cache: make cleanlib

Limitation

printf function have several limitation:

• Not support float and double (%f and %lf).
• Max text length is 80 ascii characters.

math library only have a subset of math functions.
