Hi all,

Can someone please share an example?

Hello

Hope you are well. Unfortunately, we don't have a specific example of I2C with DMA; the available examples for this part number are in the LPCOpen: https://www.nxp.com/design/microcontrollers-developer-resources/lpcopen-libraries-and-examples/lpcopen-software-development-platform-lpc15xx:LPCOPEN-SOFTWARE-FOR-LPC15XX
I suggest you refer to the periph_dma_uart example as starting point to your I2C application.

If you have more questions do not hesitate to ask me.
Best regards,
Omar
