* 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 Transmit to Address Example
|
|
|
|
This example transmits packets using CC1101 FSK radio
|
|
module. Packets can have 1-byte address of the
|
|
destination node. After setting node address, this node
|
|
will automatically filter out any packets that do not
|
|
contain either node address or broadcast addresses.
|
|
|
|
For default module settings, see the wiki page
|
|
https://github.com/jgromes/RadioLib/wiki/Default-configuration#cc1101
|
|
|
|
