Hi Christophe, after having a quick look at the Ublox Protocol Spec. and testing on a M8T it seems the only solution will incorporate some parsing of messages. The UBX-CFG-TP5 message allows for a user delay but only about +-2s and an alignment to top of second. You could however parse the UBX-T

Hi I suspect that even with setting the timepulse to 60 seconds and aligning it, you still will be routinely parsing the serial just to be sure “all is well”. There are always random things that come along and mess this or that up ….. Bob > On Feb 4, 2020, at 10:11 AM, Tim Shoppa wrote: > >

freqPeriod is in microseconds up to 2^32 so you ought to be able to set it to 60,000,000 and get one pulse a minute. If you set alignToTow will align it to the top of second but not top of minute so you'd have to parse the UTC timestamp and use it to "start" the 60 second cycle at the correct seco

Hi There are a lot of different designs out there. What you find on eBay and in most OEM systems these days has a common ground pin for everything. The typical logic on the system designer’s end is “we only have one ground on the PC board, it’s all going there immediately”. Out of a thousand d

Hi The great thing about a wire wound pot is that as a voltage divider, it has a very low temperature coefficient. The problem with adding resistors is that their temperature coefficient will not match that of the winding material on the pot. The “value” of the wire wound is lost in this case. You
