Now because I do not want to re-invent the wheel—why would any engineer?—my simple protocol uses 8-bit ASCII characters to exchange data. (An ASCII table is here.) Using this protocol, each pixel can be can be addressed by sending the following data format:

<STX> <Pixel Number> <Green><Red><Blue><ETX>

<Pixel Number>の書式が不明。
各色情報の書式が不明。

各色は8bitなので16進数表記で0x00から0xFFを送ることになるが、そのまま送ると<STX>,<ETX>とかぶることがあるだろう。
BCD(Binary Coded Decimal)形式送信なのか、あるいはACSIIで0..255を送るのか。
