Please help: with format a string with numbers or allocator instance in microzig. about microzig

Hi sorry for the late reply. For embedded projects you have to setup an allocator yourself. The easiest way you can do that is to use a fixed buffer allocator.

var buffer: [4096]u8 = undefined;
var fba = std.heap.FixedBufferAllocator.init(buffer[0..]);
const allocator = fba.allocator();

For the example above keep in mind that you can't free the memory allocated from a FBA, i.e., you have to place it strategically in your code.

If you have any questions regarding Microzig and embedded programming in Zig, the best place to go is the Zig Embedded Group Discord server (https://discord.gg/XRbsd3Ee). The response time is usually pretty quick.
