From the project
A general purpose alarm device (with software) as a module for medical devices (and others)
This is a branch with code changes useful for testing the with the PolyVent.
1. We discovered there is a BUILTIN LED load on the CLK line. This is a problem specific to the Arduino UNO architecture which we (mostly) copied. It can be solved in rework be desoldering restor R103 on the GPAD (NOT the PolyVent SPI card. 2. The code TESTPOLYVENTLINES is a very SIMPLE test script for transmitting a SINGLE BYTE. It can be loaded on to the PolyVent Architecture to remove all dependence on the (somewhat complicated) VentOS code and test the transmission of SPI through the PolyVent, back plane…
