Hi there,
I want to use arduino(UNO DUE Nano) to control ADS1298 by SPI interface.
my setup is following:
J3.3 SCLK connected to Arduino pin 13
J3.7 CS complement connected to Arduino pin 10 (CS default)
J3.8 RESET connect to Arduino pin 7 (programmed).
J3.11 DIN connected to Arduino pin 11 (MOSI default)
J3.13 DOUT connected to Arduino pin 12 (MISO default)
J3.15 DRDY connected to Arduino pin 3 (programmed)
J4.10 power supply is 5.0V
J4.9 power supply is 3.3V
J4.5 connect to Arduino GND
1) take CS LOW, SPI transfer 0x11(SDATAC ), CS HIGH then delay 5 microsecond.
2) take CS LOW, SPI transfer 0x0a(STOP), CS HIGH then delay 5 microsecond.
3) take CS LOW, SPI transfer 0x20(READ), CS HIGH.
I cannot get any data from logic analyzer and MISO bus always is Zero.
The picture is EVM jumper setting.
Many thanks
