hi i have to interface 3202 with pic 16f877a for a kit in which 3202 is connected as follows:
CS-port rd7
CLK-pin no. 15 i.e t=TICKI
DO-PIN no. 16 I.E RC1
DI-PIN no. 17 i.e. RC2
thereby disabling me from using spi feature.
Is it possible to interface it without spi feature using these pins only?
also i will like to no that for single ended modes what do + or - in ch0 and ch1 mean?
can you tell me the functioning of TICKI pin .Does it continuosly generate a clock because i was looking at a code in 8051 and there they were aartificially generating a clock for interfacing 3202
i am working as a intern somewhere.there they have made one kit of pic having multiplexed connection of pic.and changing the connections is not in my hand
cant get your question .actually the place where i am working(2 months compulsory under my college course) sell kits to colleges etc ,they have connected 3202 a long time ago but never implemented it,so i am asked to complete the task. i told them about spi feature but they are not gonna change design so have asked me to write the code other way around.
Hmmm... hope they are going to pay you extra for all your hard work !!
Should try searching the web a lot more than I did for some ready made code examples, try ' Software SPI' or 'Bit Banging SPI'.
Also look at 'PicList', they seem to have lots of code references.
