LPC17 + AIN will it work?

Testing/Troubleshooting

Hello Community

 

I wanted to know why the documentation of the LPC17 Core & AIN states: “**For MIOS32 based applications, e.g. running on a MBHP_CORE_LPC17 module, please use MBHP_AINSER64!”. **Why? Is it a supply voltage issue? Will a AINX4 work on a LPC17? I want to scan a AINX4, but want to use the LPC17 for future upgrades.

Ok I think i overlooked something. The LPC17 is limited to 8 AIN’s in the design layout. knowing this it should be capable of running 8x 4051. Am i correct?

 

I want to hook up 20 pots to the LPC17 and already have the PCB with 20 pots and 3x 4051 soldered, so the AINSER64 in not a option :no:. Will this work?

I think you are misunderstanding.

 

Without use of the MBHP_AINSER8 or MBHP_AINSER64, the max amount of pots is 8.

 

So if you use the MBHP_AINSER you can do more.

Hi

 

Thanks for the feedback. I came up with this solution (PCB2), this should work right?

I did not check the complete schedule, but the concept looks good.
