- Export
MPP_DIR
to directory that contains thempp-lib
. - Export
SYS_INCLUDE
to the directory that contains the system headers. - Export
SYS_LIBDIR
to the directory that contains the system libraries.
The toolchain and the mpp-lib you can get from the BSP sdk.
Envionment Defaults
Hi3516EV200
The Hi3616EV300、Hi3616EV200、Hi3618EV300 use the same SDK.

Building
To build the package, you must set cross compile environments first.
There is some preset in .cargo/
can help you fasten setup the cross compile.
Example:
# Setup for Hi3559AV100 boards
cp .cargo/hi3559av100.toml .cargo/config
# or for link static libraries
cp .cargo/hi3559av100-static.toml .cargo/config
# Build the package ...
cargo b
Make sure the
hi3559av100
feature is enabled in the Cargo.toml, Thehi3559av100
specified the target board, you can change to others, like:hi3531v100
Examples
use himipi_sys::{HI_BOOL, HI_MIPI_SET_HS_MODE};
use libc::{close, ioctl, open, O_RDWR};
use std::ffi::CString;
fn main() {
unsafe {
let dev = CString::new("/dev/hi_mipi").unwrap();
let fd = open(dev.as_ptr(), O_RDWR);
assert!(fd > 0);
let val: lane_divide_mode_t = lane_divide_mode_t::LANE_DIVIDE_MODE_0;
let err = ioctl(fd, HI_MIPI_SET_HS_MODE.into(), &val);
assert_eq!(0, err);
close(fd);
}
}
