I have to use the AT90CAN128 as the SPI master to communicate with the ADC ADS8344 of TI. The procedure is something like this: MCU sends a control byte to tell which channel should be measured and some configurations => MCU must generate 16 clocks to read back the data. The problem is, the clock can only be generated by sending a byte by MCU and this byte is interpreted as a control byte by the ADC. Has anyone any experiences? I would be very thankful if you could post some codes.
