Just upgraded my PoKeysDevice_DLL.dll . There is a new function l bool PoILWriteMemory(byte memoryType,ushort address,uint size,ref byte[] contents). I searched for a C# code example, and can't find one, or make it work. I have a shared slot S0 with memory address of 3377 it is for controlling a LED off of PoExtBusOC16 in poblocks it is module 10, output 7. Is there an example somewhere to follow, or can you point me in the right direction. Thanks
