i think that when onion decided to use the omega2s in the alarm clock that they decided not to release a public update to the omega2 thinking that it would reflect what the current problem status, if any, was with the alarm clock and might hurt sales.

Hi, An update, received the Onion shields and they worked without issues. Working with ControlEverything on their unit Tx for the advice all Bas

@Maximilian-Gerhardt Hi Maximillian, There is an issue with the Python code that causes reads to not return correct results (http://community.onion.io/topic/2347/issues-with-controleverything-ad7999/6). ControlEverything recommended to try the C code. I'll give your fix'ed up code a try tonight! Tx Bas

Hey, I know it's been a while since you posted, but have you had any success cross-compiling individual packages? In case you're still needing the steps: Cross-compile Instructions : Step 6b. OpenWRT build guide : Building single Packages.

I put the whole code in a loop to let it run continuously. With nothing connected, the most common result I get is 16. Don't understand what the divide by 16 (2 bytes?) does. But big coincidence that is my most common reading? If I put 2x 1.5V cell on, the reading only goes up to 33 or so Bas

@Chris-Stratton said in 48V DC-DC converter [if to off-topic, admin pls remove]: Do you want to monitor it or derive power from it, or both? They are somewhat different problems - power supplies may hide moderate variations in input voltage, while just measuring voltage could be as simple as a divider made with high value resistors (possibly a few in series) and maybe a clamp as backup input protection. Hi Chris, I should have been more clear. The way I wrote it is confusing. I'm wanting to use a Omega2 /w AD converter to measure cells of the battery bank. The input to the AD will be done using a divider circuit. My other problem is to power the Omega2 directly from that same battery bank as efficiently as possible. It's typically not recommended to use power from one of the 12V cells in the battery bank (unbalance), otherwise I could have used any cheap car adapter. @WereCatf @Ken-Conrad Awesome, thank you very much for these suggestions!!
