AT-MINI (Atmega328) CANSPI library?

[Nikitos]

Hi everyone! Is it possible to use CANSPI library with AT-MINI? I used the same code on Atmega32 and Atmega328(AT-MINI). One Atmega32 everything is working, on Atmega328 not working. I sure 100% that this code is working. Can somebody explain me something about? Or should I buy again something extra to program AT-MINI? Or should I write my own library for it?

There is only one difference. I'm using

Code: Select all

sbit CanSpi_CS            at  PORTC2_bit;
sbit CanSpi_CS_Direction  at  DDC2_bit;
sbit CanSpi_Rst           at  PORTC1_bit;
sbit CanSpi_Rst_Direction at  DDC1_bit;

Not portA or portB.

Hi,

Have you established your connection right?
You can check AT-MINI schematic to see SPI connections:

If you are using CAN-SPI board check position of onboard sw1 switches for MOSI, MISO and SCK.
Connect CAN-SPI board to MINI-AT with wire jumpers.

You should get it working.
