Detailed Description
Structure holding important informations about enc28j60 and about the latest transmission performed.
TODO: Modify this structure so you can figure out which SPI port to use (or hardcode it and keep this struct untouched, as you wish).
Member Data Documentation
◆ frame
| char* enc28j60::frame |
Used internally when asynchronous request is called and error happens to retry the request if needed.
This is an argument of enc28j60_readframe or enc28j60_writeframe.
◆ length
| unsigned enc28j60::length |
Used internally when asynchronous request is called and error happens to retry the request if needed.
This is an argument of enc28j60_readframe or enc28j60_writeframe, or this can be less if the actual length of the received frame was less.
◆ rxstatus
| uint16_t enc28j60::rxstatus |
Status read from buffer.
See datasheet page 41 and 44 and ENC28J60_RXSTATUS_* macros for testing each bit.
