Using the MPU6050 hardware DMP to solve the attitude is very simple, the following describes the three-axis gyroscope and the value of the accelerometer to use the four-number software to solve the attitude of the method.Let's take a look at how to describe a plane rotation (coordinate transformation) with Euler's angle:A coordinate system is arranged around the rotation of the α angle to obtain a coordinate system, in space there is a vector in the c

In the use of echarts, we often use the double Y axis to show the data, sometimes, we may need to set up, specific use of a y-axis to show a specific data. As shown in the figure: we have two y-axis, there are 3 data, this figure has two bad points: 1. Does not indicate that the left and right coordinates are specifically displayed, 2. It is clear that the numbe

Highcharts build the Group category coordinate axis and highcharts coordinate axisHighchartsThe Group category coordinate axis further groups the category tags of the coordinate axes to form a dual-layer and multi-layer structure. This is more conducive to the presentation of data groups. To implement the Group category axis, you must use the third-party plug-in

Two days before the second generation of hardware finally to QI, roommate Fengfenghuohuo welding out two new hardware, did not think that the magnetic field generated on the circuit board than the magnetic field is also strong, resulting in the magnetic meter data changes are not obvious, we think it is welding problems (after all, datasheet said not recommended manual welding and temperature can not exceed 260 degrees), Is the pit of a roommate a hehe ~, in fact, a correction on the good. The p

Conclusion: The chart. aligndatapointsbyaxislabel () method is used to align data points in different series along the X axis. This method should be written after binding data in different series; otherwise, the effect cannot be achieved. Analysis: Figure 1 chart. aligndatapointsbyaxislabel () Written in series bound dataBeforeEffect Figure 2 chart. aligndatapointsbyaxislabel () Written in series bound dataAfterEffect In actual data, the n

I. Why did you choose Chart.js?There were too few chart processing libraries supported by Zepto,zepto in the original Project usage library. In order to make the project more lightweight, so the selection of chart.js.But the final result is too bad, give up the char.js, or use Jquery+highstock to complete the chart needs.Overall, the project's chart requirements are low, the project requires a lighter amount, and chart.js can be used.There are several chart.js missing interfaces listed here.　　Tw
