LP11C24 ADC in, PWM out

altec1980 — Wed, 21 Sep 2022 15:09:06 GMT

Good morning,

Hope this message finds you well. I recently bought many LPC11C24 units
for academic purposes.

I would like to know if you could share a C/C++ script taking an ADC
input (from a potentiometer) and then, proportionally scaling this input to a
PWM output duty cycle (ex: to LPC_TMR32B1->MR1 on pin # R_PIO1_2 ).

I'm using the MCUXpresso IDE (v11.6.0 ). I'm also using the common
header file "LPC11xx.h".

Thanks in advance for any help.

Hi @altec1980 .

You can find some examples on the LPCOpen folder for the LPC11C24, to install it you must click on "Import project(s) from file system…" then click on "Browse" and look for the next route on the file explorer.

"MCUXpressoIDE_11.6.0_8187\ide\plugins\com.nxp.mcuxpresso.tools.wizards_11.6.0.202112161359\Examples\LPCOpen"

Install the .zip called "lpcopen_v2_00a_lpcxpresso_nxp_lpcxpresso_11c24"

Regards, Miguel.
