Hi, people
New file on the Github - testing firmware for relay test.
You can switch manually each relay, use short and long pressinng the button, no power off in this firmware, download working firmware after test.

Many thanks David for this test program.

As per my previous post re my ATU-10 PCB version, I was being very cautious in saying my Sch and thus PCB was OK as it's not easy to know what relays are operating. Or not.

I found an error in switching the 47pF capacitor using the Test program. My Schematic shows Port RE2 (Edit correction) as the Relay driver, in fact it is RE1, an adjacent pin.???? I fixed this on my proto PCB and will update the Schematic and my PCB to reflect the fixed error ASAP..

All other relay switching seems to be fine running your test, although it's not possible to check with an ohm meter if the "SW IN" or SW OUT" is working correctly as there is a path to ground in the bridge.

Hi David,

my ATU-10 doesn't work as it should, have a look at /g/ATU100/topic/89736113

Due to a hint in the thread I would like to test it more closely with Relay_Test / Manual_Test. I loaded the hex but I don't understand how to use the tests. Would be really great if you could provide a short description ...

Dear Wolf,

You'll need two push-buttons connected to the mini-Jack plug (between the Ring and Tip - to the ground). Insert it into thr remote control's socket.

Regards,
Tony
