When dialing with WINCE5.0 and SIM300 module, the system prompts: The connection with the remote computer is disconnected, please verify the "baud rate" setting and try to connect again. But I can dia...
I want to use 74151 as an 8-to-1 input selector, but I can't find an 8-to-1 output selector. I only see 74155 as a 4-to-1 selector, so I might need 2 to match the output. I wonder if there is an 8-to-...
