If you need to send or receive bytes to or from an LJM-supported device, consider using the LJM ByteArray functions.
These functions automatically split writes or reads into multiple packets, if necessary. Because of this, you can write or read a large number of bytes without worrying about what the maximum packet size of the connection is. This is especially useful for buffer registers. For example:
Name versions:
Address versions:
[C/C++] Use LJM_eWriteNameByteArray to write a Lua script to device
int LJMError; int ErrorAddress; const char * luaScript = "LJ.IntervalConfig(0, 1000)\n" "while true do\n" " if LJ.CheckInterval(0) then\n" " print(LJ.Tick())\n" " end\n" "end\n" "\0"; const unsigned scriptLength = strlen(luaScript) + 1; // handle comes from LJM_Open() LJMError = LJM_eWriteAddressByteArray( handle, LUA_SOURCE_WRITE_ADDRESS, scriptLength, luaScript, &ErrorAddress ); if (LJMError != LJME_NOERROR) { // Deal with error }
See the LJM C/C++ examples download for a full example.
