Question
X-NUCLEO-53L1A1 in MultiSensorRanging one interrupt per sensor
Hi all,
I'v modified the example of MultiSensorRanging in STM32CubeExpansion_53L1A1_V2.1.0.
I'v fitted JMP U11 and U18, and modified the file X-NUCLEO-53L1A1.h as indicated.
All sensors renging but only the centered generates interrups!
