Ouster LiDAR OS-1 (left) and OS-2 (center) Velodyne invented the modern 3D LiDAR scanner in the mid-2000s, but in recent years conventional wisdom has held that Velodyne’s design — 64 lasers mounted...[Details]
ADI has established long-term good relationships with car manufacturers and Tier 1 component suppliers. Based on its previous long-term successful cooperation with new energy vehicles and suppliers a...[Details]
OSC_IN and OSC_OUT are external crystal pins by default. If you do not use an external crystal oscillator on the STM32, how to connect OSC_IN and OSC_OUT If you use the internal RC oscillator instead...[Details]
How to convert the pin voltage value into V using the built-in ADC of STM32? V(ADC) = Value(ADC) * V(ref)/4096 (The ADC of STM32 is 12 bits, so the maximum value of the AD word is 4096)
Where V(ADC...[Details]
