* Update CC1101.h Add Max packet size for FIFO Refills * Define FIFO Size, Max packet Length for FIFO refills * FIFO REFILL - Go through FSTXON State - Check MARCSTATE to ensure ready to tx - Initial FIFO fill - Check FIFO bytes twice in accordance with errata - Refill FIFO - Check MARCSTATE is idle before returning * Fix typos * Fix another typo * min -> std::min per build check * Revert std::min back to min * Use RADIOLIB_MIN Macro instead of min * Move MARC State check for Idle to finishTransmit function Change allows startTransmit to stop blocking once the last bytes are added to the FIFO * Add timeouts for both MARC state checks * Fix typo * No interrupt for packets bigger than 64 bytes * Initialize state as RADIOLIB_ERR_NONE if avoiding ISR * Update example with packet size and discussion link * Update example with new packet size and discussion link * Update example, clarify blocking on greater than 64 bytes link discussion * Update doxygen comments for 255 byte limit, limitations and discussion link

RadioLib CC1101 Blocking Transmit Example
|
|
|
|
This example transmits packets using CC1101 FSK radio module.
|
|
Each packet contains up to 255 bytes of data with some limitations (https://github.com/jgromes/RadioLib/discussions/1138), in the form of:
|
|
- Arduino String
|
|
- null-terminated char array (C-string)
|
|
- arbitrary binary data (byte array)
|
|
|
|
Using blocking transmit is not recommended, as it will lead
|
|
to inefficient use of processor time!
|
|
Instead, interrupt transmit is recommended.
|
|
|
|
