Tested PLCIOV1P0 with CTB binaries.

AI, DI, and DO - 8 channels were working when we run separately.

But when all the AI, DI, DO run simultaneously AI is not generating. I am working on that

V1P0 Board Status

Many rework, not traceable
Tested with individual binary(with separate hardware changes) for AI, DI , DO - Working as expected. With common hardware, MISO amplitude got reduced

V1P1 assembled with host interface connector and isolator ( made config as #1 )
w/o any rework, AI, DI, DO got expected results

Observation in terminal log - In DO testing, MISO MSB was 0 in terminal log ( instead of expected 1), but DO output got correct

+In CTB, menu driven code is not functional. hence DO is tested by hardcoding the values and the generating the binary+

@Resmi K.V : Please put following in an excel sheet, upload in onedrive and give link in redmine.
Test setup, input , output (relevant details formatted and parsed ), observations, summary
upload unformatted logfile also in onedrive

PLCIO#1 - Host controller interface - Tested AI-8Ch, DI-8Ch, DO-8Ch
Issue - Observation : Observation in terminal log - In DO testing, MISO MSB was 0 in terminal log ( instead of expected 1), but DO output got correct

Tested AI and DI with Binary-1, DO with Binary-2

PLCIO#2 - no Host Interface, no AI, need to stack on #1

Hardware is ready with Daisy chaining of DI and DO

What is the plan for stacked PLCIO (8AI, 16DI, 16DO(source)) ?

Test Setup for DO Sinking atleast 100mA (Relay + LED board buy from Robu)
Test Setup for 8AI, 16DI available

DO- Binary-3 (update of Binary-2)
16DI and 8AI - Binary-4 (update of Binary-1)

@Yoganand D : Update source and binary in proj. folder and update link here, (File naming format " mDAQ2-3_CTB_Datalogger_V3.4" )

I supported testing the PLCIO hardware for 8 Channel AI, 16 channel DI and 16 channel DO.
Modified code to work in iterative to test one module after another.

  1. Completed 16 Channel DI testing.
  2. Completed 16 Channal DO testing.
  3. Completed 4 channel AI current Input Testing.

I have pushed the code, binary and the logs to my drive and have attached the link to the drive. Please find the attachment below:
