alchemist Posted December 12, 2013 Report Share Posted December 12, 2013 Hello, Can I plug the outputs of the DOUT to the inputs of the DIN modules, so that I can test them togheter through a serial line ? My idea is : - send 16 bits (16 clocks) - send latch signal - send load signal - read 16 bits and compare Will it work? Quote Link to comment Share on other sites More sharing options...
TK. Posted December 12, 2013 Report Share Posted December 12, 2013 Since you are only shifting 16 bits, I've to doublecheck: you've only connected 2 74HC165 SRs and 2 74HC595 SRs together, right? Or do you have more than 2 SRs per module? How exactly do you want to send the clock and latch/load signals? And why are you not using a common core module, running with MIDIO128 or similar, for the test? This has the advantage, that you would test the whole system. Best Regards, Thorsten.

alchemist Posted December 12, 2013 Author Report Share Posted December 12, 2013 Hello, These are the MBHP_DINx4 and MBHP_DOUTx4, so yes, they have 16 bits each one, and will test first a OUT module and 16 LEDs, then a IN plugged on that OUT, and check the output of the IN. Why I cannot test with the core? Please take a bucket of pop-corn : because I destroyed the optocoupler yesterday (yikes, I punched it and broke 1 pin, it was very late, and I was nervous...), but I ordered one other. So, the MBHP_CORE seems working (at least it doesn't burn, and voltages are OK at the control points), but with the bare bootloader. Meanwhile, I will solder the IN and OUT modules and test them with an Arduino. Quote Link to comment Share on other sites More sharing options...
