Hello all! Update: I managed to get my ESP work. 8-) It wasn't a problem with the ESP but with my cellphone... After hours of different flashing trials and without any connection to my cellphone, I finally tried to connect with my laptop. Result: Tadah! Site was loaded and after connecting to my inv...

@pilt: How do you check, if there is sketch data uploaded on the ESP? You wrote, that sometimes (or often) no files exist on the device. I wonder, how I could check this; is there a possibility to dump the complete memory to check the content? I have a similar problem as many here: I use a ESP-01 (a...

I didn't miss Siemens or Aradex or Drivetek etc. I just don't see any chance as an end customer to be able to buy them somewhere. And I agree with the quality of an OEM motor. But where do you get them from? As an original spare part, they will be even more expensive, I guess. Is there a reseller, t...

Hi all, at the moment I'm searching for a motor, that will later power my VW Golf1 Cabrio. For that, I want to have a list of motor manufacturer. My choice will be an AC (asynchron) motor, but I want to list also all other variants (DC brushed, BLDC, reluctance, etc.) for it might help other interes...

Thanks dima for the information. Now it is clear, why both *.bin files come up with address 0x0000 0000. As I wrote, I unfortunately erased the initial programming of the Olimex, does this may cause any problems or side-effects? Is the initial programming or parts of it needed for the correct functi...

Hi all, in the meantime I've ordered a ST-Link/V2-Programmer and an Olimex STM32-H103 Board and installed the "ST-Link Utility" tool. Now, I wanted to program the application and the bootloader. Therefore, I downloaded for both the *.bin file as well as the *.hex file. But what was surpris...

Ok, understood. But without R50, you don’t have a parallel-resistance to R2 (3k3 on the sense board), which leads to an overall division factor of 0,733 and a 0A-voltage of 1,83V at the µC. From a theoretical / calculative standpoint, you need a parallel resistance of 8kΩ to R2 to reach a division f...

Hello all, I have some questions about the internal analog interfaces (I’m referring to the mainboard version 3 resp. „mainboardv1.1.pdf“) 1) The current measurements are realized with the MLX91205 hall sensors, these are supplied with 5V and have an output voltage of 2.5V at 0A loadcurrent. A first...

Hi, @Johannes: I'm very sorry for calling you Jens :shock: I was so deep in technical thoughts, that my mind turned wrong with your name... But thank you all for your replies! to 1) and 2) I'll get the tools and try to get everything running. Probably, I delay the compiling topics (and leave this to...

Hello to all, first of all - as this is my first post in the forum - a short introduction from my side: I'm a 46-year old electrical engineer working at a German automotive supplier and want to build my own inverter, based on Jens' Design. As I'm a hardware guy, I have some questions about the softw...
