Do STM32-Nucleo boards support intrfacing LIDAR (RPLIDAR, YDLIDAR) modules with embedded ROS? Or do we need to interface the Nucleo MCU board with a SBC like Raspberry Pi to talk to LIDAR?

I have a prototyping project to make a wheeled-robot maneuver with LIDAR using SLAM algorithm. So, can I use a Nucleo-board to control a LIDAR device with embedded ROS without the need of a SBC like Raspberry Pi? Please refer to the image attached.

STM32L552 CMSIS DSP Performance Issue

I am using the NUCLEO-L552ZE-Q board to check the cycle counts for some of the CMSIS DSP library functions and getting unexpected results. I am comparing against ST AN4841 benchmarks and getting over 2.5 times more cycles than the Cortex-M4 in the a...

ADC reading correction per VREF_INT

Using STM32F030 Discovery board.I read the ADC channels including the internal temperature sensor and vrefint.#define TEMP30_CAL_ADDR ((uint16_t*) ((uint32_t) 0x1FFFF7B8)) #define VREF_INT_ADDR ((uint16_t*) ((uint32_t) 0x1FFFF7BA))The calibration val...

I am designing with an STM32H745. I need to use the FMC bus to access my own ASIC. What is the full cycle time on the FMC access if I do back to back single read or single write with multiplexed address/data.

The access time of the FMC is not the whole equation, I need to include the delays introduced by having to go across domains and buses. Back to back reads or writes would shine more light on this for me. Or possibly a read followed by write so that ...

The issue on FMC EXTMODE ModeA write access

Hi community,I'm developing on STM32F7, it accesses the external device via FMC.Then it can read the external device's register, but it cannot write to the register.The external device expects EXTMODE ModeA timing like the following figure. Reference...
