Function pamoja_ds18b20_build_scratchpad 

#[unsafe(no_mangle)]
pub unsafe extern "C" fn pamoja_ds18b20_build_scratchpad(
    celsius: f32,
    bits: u8,
    alarm_high: i8,
    alarm_low: i8,
    out_bytes: *mut u8,
) -> PamojaStatus

Builds the nine bytes a DS18B20 in the given state puts on the bus, CRC last.

This is the inverse of pamoja_ds18b20_parse_scratchpad, so a node can be written and tested against what a thermometer sends without one attached.

Returns

PamojaStatus::Ok on success, with the nine bytes written to out_bytes, or PamojaStatus::InvalidArgument if bits is not 9, 10, 11, or 12.

Safety

out_bytes must point to at least nine writable bytes.
