I want to use RoundDisplay and L76K GNSS at the same time, but when I connect both, the green light on the GNSS module is always on and I can’t get the time or position. I can get the time and position just fine with the GNSS module alone. How can I use both?
Welcome… which device?
without the small cell battery (not provided) attached… the memory for remembering the gps codes is lost on power ut and it may talk a while to calebrate after a cold start
there is a conflict with pin D10 being used as SPI on the display and Reset on the GPS
How can I start using it?
Hi there,
Re-map the pins you use for reset but that’s just the beginning, the Touchscreen TPint (D7) which is the Serial port f(RX)for the uart mode of the GNSS so that’s a NO-GO as well. and the SD-card CS is also SPI
here is the Xiao FP for the Round Display.
You would need to remap the SPI (MOSI) pin just for a one on one, the Round Display adds too much complexity over an I2C display and a Xiao MCU.

maybe just use another XIAO and communicate with it via bluetooth or something
