Dimmer UART communication and testing

[KKallas]

UART Communication Protocol:

• Baud Rate: 250,000 baud (bits per second).
• Data Format: 8N1 (8 data bits, no parity bit, 1 stop bit).
• Character Encoding: UTF-8.
• Frame Structure: Each message consists of the following components:
  • Start Sequence: The message starts with the characters "DS" to indicate the beginning of a data packet.
  • Command: Two alphanumeric characters that represent a specific command.
  • -> Delimiter: Use '->' to separate the command from the payload.
  • Payload: The payload of the message, which can be variable in length and content.
  • Double Colon Termination: The message is terminated by two consecutive forward slashes ("//").
  • Checksum: A checksum value, typically in hexadecimal (HEX) format, can optionally follow the double colon terminator. It helps ensure data integrity. 0000 to ignore
  • Final Terminator: The message is concluded with three consecutive colons (":::") to indicate the end of the data packet.

Example Message: DS01->Hello World//05DD::: In the example above:

• "DS" indicates the start of the message.
• "01" is the command.
• "Hello World" is the payload.
• "0A1B" is the checksum (HEX).
• ":::" marks the end of the message.
• By using '->' as the delimiter, you maintain a clear structure for your UART communication while customizing the delimiter to your preference.

Must pass:

UARTtest.ipynb

• [x] test one message with checksum
• [x] test one message without checksum
• [x] test one message with parameters with checksum
• [x] test one message with parameters without checksum repeat all with 3 messages with no params, more than one param and empty params

Answers are human readable DS10->the answers here [value] and some other text [value]//0000:::: So the non human portions can be quickly found
