C++ (Cpp) onewire_read_bytes Examples

Example #1

File: ow.c Project: AbuShaqra/nodemcu-firmware

// Lua: r = ow.read_bytes( id, size )
static int ow_read_bytes( lua_State *L )
{
  unsigned id = luaL_checkinteger( L, 1 );
  MOD_CHECK_ID( ow, id );
  u32 size = ( u32 )luaL_checkinteger( L, 2 );
  if( size == 0 )
    return 0;

  luaL_Buffer b;
  luaL_buffinit( L, &b );
  char *p = luaL_prepbuffer(&b);

  onewire_read_bytes(id, (uint8_t *)p, size);

  luaL_addsize(&b, size);
  luaL_pushresult( &b );
  return 1;
}

Example #2

File: ow.c Project: Dxploto/nodemcu-firmware

// Lua: r = ow.read_bytes( id, size )
static int ow_read_bytes( lua_State *L )
{
  unsigned id = luaL_checkinteger( L, 1 );
  MOD_CHECK_ID( ow, id );
  u32 size = ( u32 )luaL_checkinteger( L, 2 );
  if( size == 0 )
    return 0;

  luaL_argcheck(L, size <= LUAL_BUFFERSIZE, 2, "Attempt to read too many characters");

  luaL_Buffer b;
  luaL_buffinit( L, &b );
  char *p = luaL_prepbuffer(&b);

  onewire_read_bytes(id, (uint8_t *)p, size);

  luaL_addsize(&b, size);
  luaL_pushresult( &b );
  return 1;
