#define ESP32_CAN_TX_PIN GPIO_NUM_xx#define ESP32_CAN_RX_PIN GPIO_NUM_yy
I bought two FCH-Mini sensors http://www.tedcomp.se/produkter/flodesmatare/flodesmatare-fch-mini/ with 9000 p/l resolution.
- Connect e.g. MCP2562 tranceiver TX (pin 1) to Esp32 GPIO 16 and RX (pin 4) to GPIO 4.
There is a version with built-in PT100, do you think is useful to compensate for density variations? Temperature before and after the engine can be quite different.
Can I use module sach https://ru.aliexpress.com/item/MCP2515-CAN-Bus-TJA1050-SPI...
And why you would like to use external controller, while there is build in CAN?
