Hello,
I'm trying to connect my new BQ76PL536EVM board to my F28M35 control card, but things doesn't work out.
I have adapted the software for MSP430 to this uC and seems I can only write the registers. The problems I see are listed below:
1. I can not get the falling edge DRDY signal on P4 connector on the board. I have attached an interrupt (XINT1) to get this signal, but it never appears. I couldn't even check it at the scope. What else could I try?
2. Even without the DRDY, I have sent command to turn ADC_CONTROL on, initiate ADC_CONVERT and turn ADC_CONTROL off, but still without sucess.
3. I have configured the CS pin of the SPI to be drived by software, not the peripheral multiplexer. I don't know if it could be an issue.
4. I turned off the SPI FIFO. For ever register I put into TX buffer, I read the RX buffer.
5. I have already configured the CONV signal to be hardwired, but it didn't work out as well.
So, it would be great if you could send me some hints.
Thanks in advance.
