Hello,

I have trouble. I use Q2501 and i want to connect ADC with 4 wire SPI interface. As i know Q2501 suports only 3 wire SPI interface.
Does anybody knows it’s real to connect 4 wire SPI ADC to 3 wire SPI Q2501? Msybe someone can provide some solutions.

Please help it’s very important.

Thank You in advance

Hi EstDev,
You can read the SPI & I2C Bus Implementation item in the “Wireless CPU Q24 Series Customer Design Guideline” for reference.
