While doing performance tests, I noticed that the special SPI.transfer(writebuf,readbuf,count) is only called for write, but not for read.
As this massively speeds up data throughput on supported MCUs, please accept this PR.
Here:
Optimized performance on LGT8F-MCUs (Nano/Atmega328p replacement), up to 14.1Mbit/s receive and 10.7Mbit/s send.
