Re: Arduino Compatible Pro Micro (HCDVBD0013)

Sorted! Downloaded " current known working snapshot " rather than latest files at sparkfun and it's working :)

Re: Arduino Compatible Pro Micro (HCDVBD0013)

Hi I'm struggling to get this working under window. I have it recognised by the Arduido IDE (using the older 1.0.1) version but when I plugged it in the the PC Windows went ahead and installed some drivers for it anyway. I wasn't given the option of installing the pro micro drivers. Symptom is that ...

Re: SSD1306 128x64 Pixel OLED display module (HCMODU0050&2)

Hi,

In the diagram both s1 and s2 look like they are pulled to ground which would make the default SPI ? Is that correct ? The module I have is the same.

[EDIT}

Yep, it's SPI by default, which is good for me.

Re: Tiny RTC DS1307 + 24C32 Real Time Clock Module (HCMODU00

Ah! I just noticed I've been driving the RTC off of 3.3v (from an adafruit trinket) rather than 5v usb! Doh! With the fresh "4v" battery back in I get 2.8v across bat/gnd and the module doesn't work. Pop back in a 3v cell and I get 2.1 across bat/gnd and the clock works fine. The other two modules m...

Hi, I recently ordered 3 of these are 2 work fine but I was having bizarre problems with the 3rd - failing to set or read the time. After some real head scratching I checked the batteries. Two measure around 3v but the 3rd measures 4v! I swapped a ~3v battery into the problem module and it works (se...
