Simple FOC for esp32 in arduino with 東哥

 Here is the thing I purchased in Taobao

it's a modified version of simple FOC with esp32,It comes with info on git:

https://github.com/ToanTech/Deng-s-foc-controller

and a chinese colone of git: https://gitee.com/ream_d/Deng-s-foc-controller

the programing is based on:

Arduino IDE 1.8.13

SimpleFOC Library 2.1.1

ESP32 Arduino Libiary 1.0.4 

 Dong also provide a zip file for the set: https://github.com/ToanTech/Deng-s-foc-controller/tree/master/Arduino%20IDE%20for%20Deng%20FOC

but I think it's better to install yourself.

Dong also provided schematic, but in Json format, it's a format supported by easyEDA

The schematic:

U2 is a esp32: ESP32开发板 lolin32 lite

base on the schematic

IIC pins for encoder: SCL0:18 SDA_0: 19

                                  SCL1:5   SDA_1: 23

Pins for motor drive L6234:

motor0:

M0_EN        :22     

M0_IN1       :32

M0_IN2       :33

M0_IN3       :25

motor1:

M1_EN       :12

M1_IN1      :26

M1_IN2      :27

M1_IN3      :14

pins for current sensing INA240:

M0_OUT1 => M0_OUT1_CS : VN

M0_OUT2 => M0_OUT2_CS : VP

M1_OUT1 => M1_OUT1_CS : 35

M1_OUT2 => M1_OUT2_CS : 34

These pins need to be updated in simpleFOC example.

And the 3.3V for sensor pins, are from on board regulator, I read not thing with only USB powered. 

I have attacched2 AS5600 on the 2 iic bus of ESP32, the due iic sensor did not work at first shot. Since:

1. the pin out : on the Dong board I have to use this to make the example works:

   Wire.begin(19,18,400000);// for IIC0

   Wire1.begin(23,5,400000);// for IIC1

2. 12V power needed to be applied, otherwise the sensor power won't have 3.3V even yuo plug USB on ESP32.

I start to attach motor: 

BLDCDriver3PWM driver = BLDCDriver3PWM(32, 33, 25, 22);// for motor0

BLDCDriver3PWM driver = BLDCDriver3PWM(32, 33, 25, 12);// for motor0
