again: core & d-in testing

[mike303]

hi

i try it again to ask you. i finished a core and a d-in modul. upload mios_v1_9f_pic18f452.hex and setup_midibox16e.hex on the pic via midi. the d-in module are connected from j1 to j6 from core. but when i move a (endless) encoder nothing is showed in the midi monitor. how can i test the pcb's? any usefull tips are welcome.

thanks.

If yor using smash's Din board with the IDC 10 pin header, try moving the wires @ J1 of the din to the other row (NOT J2). I found that making single connectors for each cable was very useful in testing. I purchased some crimp connectors then crimped them to each wire then added some heat shrink to avoid connectors touching each other. It worked out great. Also you can go to the download page and check out the encoder test app which should be able to tell you that encoder one has been turned and so on. Good luck.

thanks for your replay. i use my own pcb and the connections between are plugable. which encoder test app you mean? i try enc_speed_v1_3.zip but no messages on

midi-in monitor. the digi-in pins are all at 4,9V. i use alps encoder and i think the left and right pins are up/down signal. the middle pin is the ground, or?

the only thing that happend when i power on is this:

ok, slowly i come out from the fog. the a-in modul @ j5 works, also the d-in modul @ j9. only d-in @ j6 isn't working yet. i use ain64_din128_dout128_v1_3 as test application. i believe thats not the right app for the j6 input's, right?

If your getting voltages at the J1 of the DIN board thats good. Try this app srio_interconnection_test_v1.zip. I think only one of the pins @ J1 isn't supposed to get voltage (can't quite remember) Does someone else want to chime in? As far as the alps encoders I would look up the specs for which is ground. I always encourage making your own stuff but smash's boards are second to none. The way solder flows on them is magical ;) Sorry if I am just repeating things that have already been said. Always search the forum for more answers as TK has probably already written about it.
