This update shows the Nucleo L476RG displaying GPS clock and position data on a pair of Nokia 5110 LCDs. Both the GPS and the LCDs are connected to the Nucleo module by a custom PCB which also incorporates a 3-axis accelerometer (which has not arrived yet) plus some switches and audio circuitry for a fuel level sensor. The electronics system is now a fully functional development platform for mobile sensors based on a powerful Nucleo Cortex M4 MCU, running off its own Lithium battery.
I struggled more than I really want to admit to get the firmware working properly, but it is now stable and doing what it is supposed to do.
This is another short update as I am still immersed in trying to get more done, but it represents a huge milestone - electronics and firmware tested and working.
