WebApr 27, 2016 · I assume the least significant byte is received first. Make sure the SPI mode is the right one, as indicated in your datasheet. If the slave can't handle being deasserted between bytes (which is what SPI.transfer() will do at the end of the transaction), then you can either try st2000's hardware SPI approach or use bitbanged SPI with shiftIn(). WebOnce a response packet is received, we call the function ethernet_UDP.parsePacket(). This function returns the number of bytes received and is waiting to be read. If the returned value is 48 bytes or more, we call the function ethernet_UDP.read() to save the first 48 bytes of data received to the array messageBuffer. rdt contracting in charleston sc
