Multi channel ADC + SPI + I2C

[GHARI.1]

I'm using STM32 NUCLEOH743ZI2 board were I have written a code which consist of Multi channel ADC using DMA with timer, SPI and I2C protocols. SPI and I2C is not working whenever multi channel ADC is enabled else SPI and I2C is working fine. We are unable to understand how multi channel ADC is effecting SPI and I2c protocols
