Multiple Sensor #7

Closed ArthurAubertin closed 1 year ago

ArthurAubertin commented 1 year ago

Is there a way to use two or more LIDAR sensors without having to rewrite a lot of argus file ?

c-berger commented 1 year ago

Hi, we are currently working on exactly that feature which will be included in the next release in approximately 2-3 months from now. A sophisticated way of operating multiple devices per MCU will become available then.

Meanwhile, only a limited support for multiple devices is available. The idea is to initialize a dedicated instance of the argus_hnd_t for each sensor and pass an unique slave identifier to the Argus_Init function that is used in the SPI layer to address the corresponding device. Once initialized, measurements can only take place in turns, i.e. a device at a time. Use the Argus_TriggerMeasurement function and wait until the measurement finishes before starting the next. Please also refer to the "simple example" on how to do so for a single device.

Hi,

We exchanged two months ago about the next release of your GitHub for multi-LiDAR sensor use. Would you happen to know more about this release?

Best regards
