Hello everyone I have one lpc1788 evolution board. There is already an SDRAM connected on the board. I want to learn how can I write data to SDRAM and read when needed. I am a beginner so any doc or link which I can visit to begin with would be appreciated. Thanks in advance.

Thanks for your reply. There is no SDK available for LPC1788 Evolution Board. Can you suggest me any other way that i can use to learn?

An EMC example in a SDK for the LPC1788 perhaps ?

Or a SDK for a similar board ?

As an embedded SW developer, you cannot always rely on ready-made examples. In the worst case, on the basis of the datasheets.

You can create a SDK for your MCU online on the NXP website, and download it. With plenty of options to include middleware components like communication protocols, or graphics. Have you tried that ?

Select you MCU on the NXP product page, and go to the Design Resources / Embedded Software page:

I don't really know the LPC1788.

Trying to check that myself, I couldn't find my way through. Not sure if the LPC17xx is supported by the SDK generation tool (https://mcuxpresso.nxp.com/en/welcome).

Perhaps the NXP staff can chime in.

Hello @frank_m,

This MCU is not supported in the SDK, this has a library called LPCOpen where you can find examples for most of the peripherals (link), there's an example code called periph_memtest that use an external DRAM that you could take a look.

Best Regards,

Alexis Andalon

SDK examples for your eval board ?

Worked for me, with a LPC54xxx board.
