| 説明 | Fischertechnik - Lego project.This is the TXT scope recording function. The signals come from the Lego mindstorms 51515 color sensor.There are 16 balls of 14mm in 4 colors. They are passed through a feeder. The slope is about 10 degrees. There are approximately 4 balls running per second. A lego color sensor reads the color of the rolling balls and sends the new data serially to the Lego hub port every 10 msec. This serial line is also intercepted by the FPGA module. Thus, the sensor info is simultaneously available to lego and to the FPGA without the need for additional software. The TXT now reads this data from the FPGA via an I2C. The readout is a separate task that can ideally be done every 10 msec. Thus, the new data is available in the TXT for further processing. You can further see the TXT program in this pictures:flic.kr/p/2nmYUNMflic.kr/p/2nmWkzYA video of how the balls are processed can be seen here:flic.kr/p/2nmLDa1With this TXT scope record, you can see the results. On the red signal, you can see that the data sometimes goes on and off. The program takes this into account so that no additional false sequences are counted.The blue signal sometimes switches between the value 3 and 4. This has also been taken into account when counting the colored balls.For Lego, the program word blocks is used. For the TXT, the RoboPro software is used. |
