Thu, 20 Nov 2008 22:12:15 -0800 http://backend.userland.com/rss092 I am reading the ADC of the master controller and sending the data to the slave through SPI.Master is sending the data accurately, but slave is receiv <noauthor@nospam.com> http://www.8051projects.net/forum-t7020.html i do not understand this..you are sending one byte and on receiver side you are getting bytes like 8 or 9 bytes... Ajay<contact@nospam.com> http://www.8051projects.net/forum-t7020.html I am sending from master 179 continuously, while slave is receiving the correct byte after 8 or 9th byte.That is correct data received after every 8th Hanzala<hanzala1409@nospam.com> http://www.8051projects.net/forum-t7020.html can you explain me in the slave code what are you doing here? and why?CODE:output_b(data);
            &nbs Ajay<contact@nospam.com> http://www.8051projects.net/forum-t7020.html By toggling D4 I am just want to make sure that slave is receiving the data and I am sending this data on port B. I have attached LED's on Port B and Hanzala<hanzala1409@nospam.com> http://www.8051projects.net/forum-t7020.html try doing this way...in slave controller setup SPI as..CODE:setup_spi(SPI_SLAVE|SPI_L_TO_H|SPI_SS_DISABLED);i mean.. L->H data transition.. pl Ajay<contact@nospam.com> http://www.8051projects.net/forum-t7020.html It is still not working properly. May be it is a synchronization problem. Does any one has a program which he has tried himself?Can any one tell me th Hanzala<hanzala1409@nospam.com> http://www.8051projects.net/forum-t7020.html hello, Maybe the 'master' is running (and sending data) faster than the slave (because it has few instructions). Therefore, the data in the slave PI Rocha<fabio.rocha@nospam.com> http://www.8051projects.net/forum-t7020.html
