complete !

Finally all is ready !

The result is not bad at all we only have just two minor issues:

• pin 4 of the DIP switch was not connected to the board solder island (re solder)
• led order is not parallel with power outlets (can be mapped in software)

I'm now started with converting my proof of concepts I did on the olimex board to our brand new board. I test every block code as I move on. Small video below shows the testing of the timers. At the moment this not yet synchronized with the zero cross and FIR it just tests the timers and nvic module. Next step will be testing the ADC and FIR for the zero cross detection.

Also the button test board (see picture) is now connected so we have a nice test kit for 12 in and outputs. Having these helper tools is indispensable as preparation for the final production release.

Button test board:

Power test with timers:

first test succeedded

Running leds as integration test:

Next test will be with power connected.

jtag testing

At the moment we do the first testing with raisonance JTAG interface:

the core is on

As promised the pictures of the cortex core:

sequel components

This time the trafo is added and other related stuff. The trafo is not used for supply reasons but to feed a reference signal for FIR filter ADC input signal.

Capacities and diodes used to work with plus/min voltages of the trafo:

What is left to do is the cortex mcu and some related resistors, capacities and crystals. So let's say ready for 75%. Next blog will be pictures focued on the cortex. Hopefully we can do the integration tests in couple of days from now. Of course these results will be posted in this blog topic.
