Hello everyone, First things first this appears to be an amazing group with a wonderful project behind it. Second, I’m planning on making my own equatorial mount, capable of carrying around 75-80 lbs

#arduino #ascom #drv8825 #ds3231 #skyplanetarium

Yeah, I like the L2596S DC-DC bucks. They give you an assured 3A out, ara cheap enough and easy to use with the granular pot. The OKI type with fixed output is safer, but I have to be careful not to m

Finally got it working. Howard Dutton is right, both Stm32f103s I had were bad . I ordered a new and as soon as I flashed it, everything worked as expected. It just took a month to ship from China. I

Still no luck, Here's the relevant config file parameters I'm using as well as the flash command I'm using too: // Parameter Name Value Default Notes Hint #define PINMAP STM32Blue // OFF, Choose from:

Thanks for the replys, I'll give re flashing with the libraries a try and see how it goes. Hopefully I can get it working. I'll post what I end up doing.

I'd say its very likely a hardware problem of some sort. A bad PCB, bad soldering, bad Stm32f103 that sort of thing. Seems very unlikely its the DS3231 RTC / AT24C32 EEPROM module as you've tested els

It has been some time since i used the onstep bluepill so my memory has faded but have you tried the bluepill memory size test? they were available in 64k and 128k ( officially bluepills are only 64k

Anyone?

#bluepill #blackpill #ds3231

I've put together a Bluepill board from a PCB kit from George with OnStep V4 flashed to a Stm32f103. The problem is when I power it on I get "NV (EEPROM) failure!" Everything I've read points to probl

Received the new RTC DS3231 today. I2C scanner picks up both RTC and epprom. So seems to be good. I couldn't find any faults on the other board SMT solders, but refused to pick it up with separate ard

Thanks for the quick reply! I will order another and also get this under the microscope at work tomorrow to see if there is a leg of the ds3231 that has been lifted. I also found out I need to desolde

#rtc #blackpill #maxstm3 #ds3231 #pps

Yes. The DS3231 is not being detected. The NV chip (AT24C32 EEPROM at 0x57) is there and appears to be working. We've seen SMT soldering problems on ZS042 modules before. I'd check/fix that and/or try

Measured battery, is at 3.3V and was taken from a newly bought package. Soldering appears to be good. I measured RTC chip getting power from battery on the chip pins. Pin-socket on PCB has good solder

First, check battery voltage and check if battery is properly inserted (it can be shorted if inserted inproperty by accidentally bending contact plates). Then connect RTC module to other device (i.e a

#rtc #blackpill #maxstm3 #ds3231 #pps

Battery? Bad DS3231? Bad soldering? Jumper installed under the DS3231 that connects PPS to Aux2? EEPROM is a separate chip. No. This feature has been tested and is working. Turn on debug mode (OnStep.

Hi So first of all, massive thanks to everyone helping and contributing to this project. I am new in the astro world but stuff like this is amazing! Had a fun time getting it all collected and built!
