![]() The link may be broken and re-established, so a receiving MCU should be able to start receiving mid-packet, and have a simple way of telling when the next packet has begun, so it can ignore data until the end of that partial packet. ![]() - data link escape and start of headingīut what if the payload is binary data containing two consecutive bytes equivalent to DLE and ETX? how should those bytes be escaped?.The Wikipedia page on control characters says a packet could be sent like this: The problem: either I'm not understanding it correctly, or it's not capable of doing what I want. I would rather not re-invent the wheel, so I'm wondering if some ASCII implementation would work, using ASCII control characters in some standard way. To do this, check the type plate voltage above the power inlet at the back of the printer. User guide Installation Checking the printer Make sure that the device has been set to the correct voltage (e. You can check one ascii table or the device manual to see the hexadecimal values of this chars. I want a simple, light-weight way for two basic 8-bit MCUs to talk to each other over an 8-bit UART connection, sending both ASCII characters as 8-bit values, and binary data as 8-bit values. Also en- sure that there is sufficient space for the printed output. Hi Willy, Normally this are hexadecimal control chars. ![]()
