PPS info missing

Post by jfrydrys » Tue 16. Aug 2016, 13:48

I am trying to figure out how to read and transmit ´Pulse per Second´ signal over CAN. It's pin 4 of u-blox MAX-7W chip but I haven't found in manual whether it's even connected to the NXP LPC40xx or how to do it.

Yes, you could use the TIMEPULS Signal for internal use. We have build a example which use this PIN to generate a IRQ for sending CAN Frames. The PIN 4 (PPS) of the uBlox Device is connected to the GPIO of the used µC (P0.29),
Please see sample "Irq" on the Product DVD --> Develop\Microcontroller hardware\PCAN-GPS\Examples\Irq\
