Other Parts Discussed in Thread: ADS1298R
I meet some problem with spi communication for ADS1298R. I try everything include the following steps:
I just replace the control pins throuth my MCU instead of TMS320, all the settings is default of the board, including the power supply.
I find that the mmb0 board spi signal level is about 5V, Now I need use my MCU to control ADS1298R,
but my chip spi is cmos level(3.3V). Could I use the 3.3V spi directly communicate with ADS1298R?
