Creating a project in mcuxpresso using only cmsis defined access layer

[topspin]

Hi community,

I would like to create a new project in mcuxpresso for the lpc845 microcontroller using only the cmsis files to access the peripheral registers. I do not want to use an sdk or other higher level layers.

As far as I know I should only need the lpc845.h file and some other files related to the clock.

Can you help me?

Is there a reference document for this topic?

Best regards

Hi @Alice_Yang 

thanks for the support. 

In this way I am able to create a project with the following structure

but I do not see the LPC845.h file that let me access to the register with the CMSIS definitions. Where can I find it?

Let's say that I currently have some fuctions  like this one below made for the LPC8xx microcontroller

void spi0_init(void){

LPC_SYSCON->SYSAHBCLKCTRL|=(1<<11); /* enable clock to SPI0 */
LPC_SYSCON->PRESETCTRL&=~(1<<0);
LPC_SYSCON->PRESETCTRL|=(1<<0); /* reset SPIO0 */

LPC_SPI0->DIV=12; 

LPC_SPI0->CFG=CFG_MASTER | CFG_ENABLE; /* enable SPI0 as master */
}

My goal it is to create a project to have all these functions running on the LPC845 instead of the LPC82x therefore I need the LPC845.h file to rewrite everything with the correct syntax.

I hope you can help me.

Best regards

Hello @topspin 

It seems from  legacy driver Code_Bundle, you can import demo as my attachment video, then development your own code based on it.

Hi alice,

First of all thanks for the video. However it is really short and barely understable. Can you do a more detailed one?
The video stops after you press "deselect all". Which are the next steps?

Hello  

Just show you how/where import Code_Bundle demo, next steps is based on your own requirement to import which demo, then it will generated the project like you said above.

Hello @topspin 

When create new project, you don't have to choose SDK, as below:
