|
||||
|
||||
## Installation
|
||||
1) install [esp-idf](https://docs.espressif.com/projects/esp-idf/en/stable/esp32/get-started/index.html#installation) if not installed on your computer already
|
||||
2) open esp-idf terminal
|
||||
3) plug in your esp32 to computer via USB cable
|
||||
4) Run these commands:
|
||||
```
|
||||
git clone https://github.com/PrincessPi3/Sillyfilly-CAN.git
|
||||
cd Sillyfilly-CAN
|
||||
idf.py set-target esp32s3 # example idf.py set-target <your_esp32_ type>
|
||||
idf.py menuconfig
|
||||
```
|
||||
5) Under "Sillyfilly-CAN Configuration" set your settings like wifi and CRX and CTX pins.
|
||||
6) Wire transceiver to the pins: CRX->RX, CTX-TX, GND->GND
|
||||
7) run this command
|
||||
```idf.py flash monitor # ctrl+] to exit monitor```

# Installation
|
||||
```
|
||||
git clone https://github.com/nopnop2002/esp-idf-can2http
|
||||
cd esp-idf-can2http
|
||||
idf.py set-target {esp32/esp32s2/esp32s3/esp32c3/esp32c6}
|

idf.py menuconfig
|
||||
idf.py flash
|

```
|
||||
|
||||
# Configuration
|
||||

|
||||

|
||||
|
||||
## CAN Setting
|
||||

|
||||
|
||||
## WiFi Setting
|
||||

|
||||
|
||||
You can use static IP.
|
||||

|
||||
|
||||
You can connect using mDNS.
|
||||

|
||||
|
||||
## External HTTP Server Setting
|
||||
The External HTTP Server receives CAN Bus received data.
|
||||

|
||||
|
||||
__Note__
|
||||
The Built-in HTTP Server receives CAN Bus transmittion data.
|
||||
|
||||
# Definition from CANbus to HTTP
|
||||
When CANbus data is received, it is sent by HTTP POST according to csv/can2http.csv.
|
||||
The file can2http.csv has three columns.
|
||||
In the first column you need to specify the CAN Frame type.
|
||||
The CAN frame type is either S(Standard frame) or E(Extended frame).
|
||||
In the second column you have to specify the CAN-ID as a __hexdecimal number__.
|
||||
In the last column you have to specify the HTTP-POST-Path of external HTTP server.
|
||||
Each CAN-ID is allowed to appear only once in the whole file.
|
||||
|
||||
```
|
||||
S,101,/post
|
||||
E,101,/post
|
||||
S,103,/post
|
||||
E,103,/post
|
||||
```
|
||||
|
||||
When a CAN frame with ID 0x101 is received, POST with the 'canid':257.
|
||||
When a CAN frame with ID 0x103 is received, POST with the 'canid':259.
|
||||
|
||||
POST Parameter Example:
|
||||
CAN-ID is a decimal number, not a hexadecimal number.
|
||||
|
||||
```
|
||||
{"canid":257, "frame": "standard", "data": [16, 17, 18]}
|
||||
{"canid":257, "frame": "extended", "data": [16, 17, 18]}
|
||||
{"canid":259, "frame": "standard", "data": [16, 17, 18]}
|
||||
{"canid":259, "frame": "extended", "data": [16, 17, 18]}
|
||||
```
|
||||
|
||||
__CAN messages not registered in csv/can2http.csv are discarded and not POSTed to HTTP.__
|
||||
|
||||
# Definition from HTTP to CANbus
|
||||
Not exist.
|
||||
You can send any CAN-ID.
|
||||
|
||||
|
||||
# Send CANBus frame using curl
|
||||
CAN-ID is specified in __decimal number__.
|
||||
```
|
||||
$ curl -X POST -H "Content-Type: application/json" -d '{"canid": 513, "frame": "standard", "data": [16, 17, 18]}' http://esp32-server.local:8000/api/twai/send
|
||||
twai send successfully
|
||||
|
||||
$ curl -X POST -H "Content-Type: application/json" -d '{"canid": 513, "frame": "extended", "data": [16, 17, 18]}' http://esp32-server.local:8000/api/twai/send
|
||||
twai send successfully
|
||||
```

|
||||
|
||||
## Using node.js
|
||||
There is a lot of information on the internet about the node.js + __real time__ visualization library.
|
||||
- [epoch](https://epochjs.github.io/epoch/real-time/)
|
||||
- [plotly](https://plotly.com/javascript/streaming/)

||||
|
||||
# Troubleshooting
|
||||
There is a module of SN65HVD230 like this.
|
||||

|
||||
|
||||
There is a __120 ohms__ terminating resistor on the left side.
|
||||

|
||||
|
||||
I have removed the terminating resistor.
|
||||
And I used a external resistance of __150 ohms__.
|
||||
A transmission fail is fixed.
|
||||

|
||||
|
||||
If the transmission fails, these are the possible causes.
|
||||
- There is no receiving app on CanBus.
|
||||
- The speed does not match the receiver.
|
||||
- There is no terminating resistor on the CanBus.
|
||||
- There are three terminating resistors on the CanBus.
|
||||
- The resistance value of the terminating resistor is incorrect.
|
||||
- Stub length in CAN bus is too long. See [here](https://e2e.ti.com/support/interface-group/interface/f/interface-forum/378932/iso1050-can-bus-stub-length).

# Installation
|
||||
```
|
||||
git clone https://github.com/nopnop2002/esp-idf-can2http
|
||||
cd esp-idf-can2http
|
||||
idf.py set-target {esp32/esp32s2/esp32s3/esp32c3/esp32c6}
|
||||
idf.py menuconfig
|
||||
idf.py flash
|
||||
```
|
||||
|
||||
# Configuration
|
||||

|
||||

|
||||
|
||||
## CAN Setting
|
||||

|
||||
|
||||
## WiFi Setting
|
||||

|
||||
|
||||
You can use static IP.
|
||||

|
||||
|
||||
You can connect using mDNS.
|
||||

|
||||
|
||||
## External HTTP Server Setting
|
||||
The External HTTP Server receives CAN Bus received data.
|
||||

|
||||
|
||||
__Note__
|
||||
The Built-in HTTP Server receives CAN Bus transmittion data.
|
||||
|
||||
# Definition from CANbus to HTTP
|
||||
When CANbus data is received, it is sent by HTTP POST according to csv/can2http.csv.
|
||||
The file can2http.csv has three columns.
|
||||
In the first column you need to specify the CAN Frame type.
|
||||
The CAN frame type is either S(Standard frame) or E(Extended frame).
|
||||
In the second column you have to specify the CAN-ID as a __hexdecimal number__.
|
||||
In the last column you have to specify the HTTP-POST-Path of external HTTP server.
|
||||
Each CAN-ID is allowed to appear only once in the whole file.
|
||||
|
||||
```
|
||||
S,101,/post
|
||||
E,101,/post
|
||||
S,103,/post
|
||||
E,103,/post
|
||||
```
|
||||
|
||||
When a CAN frame with ID 0x101 is received, POST with the 'canid':257.
|
||||
When a CAN frame with ID 0x103 is received, POST with the 'canid':259.
|
||||
|
||||
POST Parameter Example:
|
||||
CAN-ID is a decimal number, not a hexadecimal number.
|
||||
|
||||
```
|
||||
{"canid":257, "frame": "standard", "data": [16, 17, 18]}
|
||||
{"canid":257, "frame": "extended", "data": [16, 17, 18]}
|
||||
{"canid":259, "frame": "standard", "data": [16, 17, 18]}
|
||||
{"canid":259, "frame": "extended", "data": [16, 17, 18]}
|
||||
```
|
||||
|
||||
__CAN messages not registered in csv/can2http.csv are discarded and not POSTed to HTTP.__
|
||||
|
||||
# Definition from HTTP to CANbus
|
||||
Not exist.
|
||||
You can send any CAN-ID.
|
||||
|
||||
|
||||
# Send CANBus frame using curl
|
||||
CAN-ID is specified in __decimal number__.
|
||||
```
|
||||
$ curl -X POST -H "Content-Type: application/json" -d '{"canid": 513, "frame": "standard", "data": [16, 17, 18]}' http://esp32-server.local:8000/api/twai/send
|
||||
twai send successfully
|
||||
|
||||
$ curl -X POST -H "Content-Type: application/json" -d '{"canid": 513, "frame": "extended", "data": [16, 17, 18]}' http://esp32-server.local:8000/api/twai/send
|
||||
twai send successfully
|
||||
```

# Visualize CAN-Frame
|
||||
|
||||
## Using python
|
||||
There is a lot of information on the internet about the Python + visualization library.
|
||||
- [matplotlib](https://matplotlib.org/)
|
||||
- [seaborn](https://seaborn.pydata.org/index.html)
|
||||
- [bokeh](https://bokeh.org/)
|
||||
- [plotly](https://plotly.com/python/)
|
||||
|
||||
## Using node.js
|
||||
There is a lot of information on the internet about the node.js + __real time__ visualization library.
|
||||
- [epoch](https://epochjs.github.io/epoch/real-time/)
|
||||
- [plotly](https://plotly.com/javascript/streaming/)

|
||||
# Troubleshooting
|
||||
There is a module of SN65HVD230 like this.
|
||||

|
||||
|
||||
There is a __120 ohms__ terminating resistor on the left side.
|
||||

|
||||
|
||||
I have removed the terminating resistor.
|
||||
And I used a external resistance of __150 ohms__.
|
||||
A transmission fail is fixed.
|
||||

|
||||
|
||||
If the transmission fails, these are the possible causes.
|
||||
- There is no receiving app on CanBus.
|
||||
- The speed does not match the receiver.
|
||||
- There is no terminating resistor on the CanBus.
|
||||
- There are three terminating resistors on the CanBus.
|
||||
- The resistance value of the terminating resistor is incorrect.
|
||||
- Stub length in CAN bus is too long. See [here](https://e2e.ti.com/support/interface-group/interface/f/interface-forum/378932/iso1050-can-bus-stub-length).
