The EVALKIT-VL6180X is an evaluation kit that provides an introduction to the proximity, ranging and light sensing capabilities of the VL6180X sensor, combined with the powerful STM32 F401RE microcontroller.
The STM32 Nucleo board provides an affordable and flexible way for users to try out new ideas and build prototypes with any STM32 microcontroller line, choosing from the various combinations of performance, power consumption and features. The Arduino™ connectivity support and ST Morpho headers make it easy to expand the functionality of the STM32 Nucleo open development platform with a wide choice of specialized expansion boards.
The VL6180X plug-in features the VL6180X proximity sensor, based on ST’s FlightSense™, Time-of-Flight technology, and provides very accurate ranging information, as well as ambient light sensing (ALS) information. The range measurements are independent of the target reflectance.
Key Features
1 Nucleo board with STM32 F401RE microcontroller in LQFP64 package
Flexible board power supply
USB VBUS or external source (3.3 V, 5 V, 7 - 12 V)
Power management access point
1 VL6180X (proximity, gesture and ambient light sensing module) plug-in.
Slider switch controlling 2 functions:
4-digit display, displaying either the distance of a target from the proximity sensor or the lux value from the ambient light sensing (ALS).
Excellent ranging accuracy, independent of the reflectance of the target.
Equipped with Arduino UNO R3 connector.
RoHS compliant.
Full system SW supplied, download from www.st.com/vl6180x in the folder “Design resources.
VL6180X satellite board2 can be soldered to the plug-in board through flying wires, in order to integrate the VL6180X in customer’s application.
Basic gesture recognition application can be developed using the VL6180X sensor on the plug-in board or a dual sensor application by connecting a VL6180X satellite to the board.
现在用岭仪的WIFI硬件平台为PXA270接口为SPI目前系统初始化完SPI,然后读WIFI的ID可以正常通过但是到加载固件时函数static int sbi_download_wlan_fw_image(const u8 *firmware, int firmwarelen)下有时:do {tmp++;NdisStallExecution(10); //
接入信号发生器老不能正常显示频率,因此我把程序简化再简化。。。最后就让信号发生器来一个高脉冲,计数器就加1,但是即使如此数码管上的数还是乱跳。。。我都不知道是什么问题。。。数码管显示程序是无问题的,因为我在其他程序中用过。我把程序简略的发上来大家帮我看看,多余的东西我都删了(包括输出)。。我感觉就是这部分有问题,不知道用什么进制来计数有限制吗?input s
