Justification[edit]
Robust, wireless communication between multiple PCB boards decreased design constraints and wiring, allowing for much more modular and adjustable designs capable. This would allow for mobility, ease of communication, reduced clutter, and scalability. Could potentially
Current Methods of Integration[edit]
ESP32 Built-In[edit]
Connections[edit]
UART Communication[edit]
- Hook up UART_TX and UART_RX to STM32.
I2C Communication[edit]
SPI Communication[edit]
Firmware[edit]
Examples[edit]
* ESP32 Chip adjusted specifically for the sole purpose of wireless communication. * Interfaced with using UART *
- uses UART To both receive and send data to other modules
Pros and Cons[edit]
Pros[edit]
Allows for convenient, easy to mount access to wireless communication. Easy to interface with, using UART in order to communicate data.
Cons[edit]
Bluetooth Modules[edit]
Component Selection[edit]
HC_05/HC_06[edit]
CYM4343W[edit]
Contains both Bluetooth as well as Wifi protocols Uses UART for Bluetooth Uses SDIO for wifi communication
Pros and Cons[edit]
Pros[edit]
- Simple implementation with supported Code
Cons[edit]
- Separate PCB Board interfaced with/ Not modular.
TODO[edit]
Look into the specific components of the Bluetooth modules to find ICS that can be easily used and interfaced with. Figure out how to interface with ESP32 software using STM32, how to send specific commands, etc.
Interfacing with Other Boards[edit]
Network Setup[edit]
Access Point[edit]
Set up one device as the master. Intended purpose of the CANdaddy. Host signal and allow other devices to connect using SSID and password. In the case of the ESP32, this is done through built in libraries that allow for
