My solution didnt do anything wildly clever,it just oversamples the input 8 times.Looks for transitions on the input and uses a filter to work out where the middle of the bit should be.In this simulation you can see the input transtion being detected.The signal filter points to where the middle of the bit should be and the signal filter_hi2lo is where the input is sampled and the ouptout is set.Basically it just uses a lot of timeers which are started by transitions.As you can see here
http://www.8052.com/users/jezwoldspage/man1.ps the problem iam doing manchester decoding using pca of sst89e564rd mcu. for this i don't have the debugging tool.so i tried this logic in 8051f020 using pca feature . using this mcu i could get the decoded data successfully. finally my code i have to implement on the sst89e564rd.so when i loaded this logic in sst mcu i am not getting the result.i have set the configuration for pca timer of sst mcu.but iam not getting the output. for this i am using CEX0 on which manchester encoded data is received.i need to decode this data. i need some suggestion and help on this problelm |
