Datasheet: Esp32c3 datasheet
Hi, I am trying use this lib on esp32c3 on arduino which has 3 spi.spi 2 is for normal use. By compare de loopback example. I am define cs pin 10, int pin 3. sck pin 6, mosi pin 7, miso pin 2.
replace SPI.begin() to SPI.begin(6,2,7,-1);
Everything looks working but cannot call int function onReceiveBufferFull.
I tried other mcp2515 library and get the same result. I am also tried anoter pin define. becuz esp32c3 said spi2 could be any pins. But nothing works.
Minimum example code to replicate the bug
void setup()
{
pinMode (12, OUTPUT) ;
digitalWrite (12, HIGH) ;
//--- Start serial
Serial.begin (115200) ;
while (!Serial);
/* Setup SPI access */
SPI.begin(6,2,7,-1);
pinMode(MKRCAN_MCP2515_CS_PIN, OUTPUT);
digitalWrite(MKRCAN_MCP2515_CS_PIN, HIGH);
/* Attach interrupt handler to register MCP2515 signaled by taking INT low */
pinMode(MKRCAN_MCP2515_INT_PIN, INPUT_PULLUP);
attachInterrupt(digitalPinToInterrupt(MKRCAN_MCP2515_INT_PIN), [](){ mcp2515.onExternalEventHandler(); }, LOW);
mcp2515.begin();
mcp2515.setBitRate(CanBitRate::BR_250kBPS_16MHZ); // CAN bit rate and MCP2515 clock speed
mcp2515.setLoopbackMode();
std::for_each(CAN_TEST_FRAME_ARRAY.cbegin(),
CAN_TEST_FRAME_ARRAY.cend(),
[](sCanTestFrame const frame)
{
if(!mcp2515.transmit(frame.id, frame.data, frame.len)) {
Serial.println("ERROR TX");
}else{
Serial.println("OK TX");
}
delay(1000);
});
}
the terminal just shows:
OK TX
OK TX
OK TX
OK TX
OK TX
OK TX
OK TX
