Where can I get the C Library for the powerline trancievers ST7570 and ST7580 described in User Manual UM1070?
http://www.st.com/internet/com/TECHNICAL_RESOURCES/TECHNICAL_LITERATURE/USER_MANUAL/DM00026249.pdf The distributor where I purchased two EVALKITST7570-1 has no further information. The Online-Support from ST failed to respond. #arduino #st75802013-01-31 08:46 PM
Hello,
I'm having a problem interfacing my ST7580 using Arduino Mega USART. And I think I already broke 2 pcs of it and I cannot afford to lose some more.Please help me code to PING, Read/Write MIB and send even simple PHY data over the powerline.The Arduino code I used is here..../* Arduino Code – ST7580 Transceiver BoardCode Consideration: Not sure if syntax and arguments in User Manual work with all types of microcontroller. Just to be sure, per byte transmission will be used. For fields with >1 byte, endianness is assumed to start with byte index 0, which is the logical thing to do.Code Author: Patth Rick L.
