Sie arbeitest sehr schnell! I'm impressed with how quickly you are moving through the phases. Also, how much quality of engineering you employ. Gut erledigt!

I found Olimex to be less than quality. In fact, no matter how impressive the ad, and how cheap the price, if I see Olimex, I run away. You confirmed my personal experience with that company. Sorry for your frustrations nonetheless.

It wasn't until I got to the last post that I realized this thread is 10 months old. The thought I had is that CAN and I2C both use addressing protocols. Whether it's CAN, I2C, or UART, a custom protocol can use addressing schemes to get unaffected MCUs to ignore transmissions (software instead of h...

I looked into Arduino a couple of times, but I like the control of using just the processor itself. I work with the PIC line. Microchip now has a line of Nano boards that allow you to interface the PIC processor like you would an Arduino. The PIC community suffers its own challenges with Microchip C...

There are many YouTube tutorials on soldering SMT parts, here's one:



You can look in the right side bar for more when you get to YouTube for more ideas.

My experience has been with the Microchip PIC processors. What I found is that parts more than about a decade old are slow, limited, and expensive. Newer offerings are faster, offer more peripherals, and are cheaper. I looked up the ST part number you're working with and it appears to be about 15 ye...

I work with PIC processors, but it may have something to do with page size. You may be filling a page and overflowing to another, and the context of usage cannot deal with that. Look at the disassembly for addressing to see where your linker is putting it. That may show you what's happening.

Just read through the entire thread. You mentioned using large value resistors for the resistor divider to keep parasitic losses to a minimum. A trick I use is to use a P-MOSFET (like a TP2104) to connect the battery to the high side of the resistor divider. Then I use much smaller resistor values. ...
