The relationship between variable 'speed' and the real angular velocity of the wheel?

I am working on a project require accurate measure of the angular velocity of the wheel. The most related variable is in https://github.com/MoebiusTech/MecanumRobot-Arduino-Uno/blob/master/arduino%20ps2 , line26, char speed;//小车速度

What is the relationship between variable 'speed' and the real angular velocity of the wheel?

The actual angular velocity could be effected by motor power, size of wheels etc. The number of speed should be related to these measurement. And what is the that relationship?

我正在做一个基于你们这个四轮车的项目，需要比较精准的轮子转速相关的参数。所以想问一下你们在设立 speed这个variable的时候，具体的数字int speed传进这个代码里和轮子实际的角速度是怎样一个关系？

可以不考虑轮子和地面的摩擦，只是空转的话，这个数字是不是和空转角速度有关呢？如果是的话，单位/scale是什么？

uno-pca9685.zip is not being added in the arduino IDE library

Hi, When I try to add the "uno-pca9685.zip" in the Arduino IDE add library it gives the following error (attached). Can you tell where to included "FaBoPWM_PCA9685" library as the name is also not same in the repo? Please check and let me know.

How to resolve this issue?

Servo random movement right after upload

Hi,

The servos move to random position during Arduino upload, is there any way I can solve it? The /OE is tied to GND on the PCB....

Thanks

Wire connected to A4/A5 instead of SCL/SDA pin

According to https://www.arduino.cc/en/reference/wire.
The board didn't work with mega256 and a lot of other board.
It work only for UNO and Ethernet board.

PCA9685 library issue

Hi,

I am getting this error after even after installing the PCA9685 library. attached is the serial output

Expected 0x41, 0x73 or 0x79, but got FF
No controller found, check wiring, see readme.txt to enaFind PCA9685
StartController mode not matched or no controller found
