Well, this blog is supposed to be about work, so here we go.
We submitted a UL build. They immediately found problems, you poke a pin
through a ventilation hole and hit the motherboard. fail. But they will
continue testing.
Then we have more features to be piglab tested. eventually the customer will
run real surgeons with the tool. Plab is tuesday, with new features.
There are response time questions; incomplete safety checks; incomplete
alarms; etc. But they want the ability to modify tool scripts by themselves,
which means making a toolchip programming system --not the crypto (authentication
capable) ics but simple spi eeproms. have to drive them via tool interface boards which have a PIC 16F part and speak RS485. They will get commands from a pc running
a 485 protocol to program the chips.
