LPC43S37 analog pin?

luca_bonora89 — Sun, 28 Apr 2019 23:21:56 GMT

Hi everybody, I have got an PLC43s37 and I'm looking for a way to configure an analog pin on the board to read a value from a sensor, temperature for example?

Hello luca bonora,

You can download and refer to the LPCopen , there is periph_adc demo:

LPCOpen Software for LPC43XX | NXP

Hope it helps,

Have a great day,

Thanks a lot Alice, I'm reading that book very deep... my question is even easier: if I want to use one of the analog pin (A0-A5), how I know which GPIOx[y] pin it refers??

Hello Luca,

Please refer to User Manual about "Table 1108.10-bit ADC0/1 channels for different packages on parts LPC435x/3x/2x/1x (without 12-bit ADCHS))".

About how to enable the pins to ADC function, please have a look at "17.4.6 ADC0 function select register" of UM.

Have a great day,
TIC

Hello Alice and thanks a lot!

Now that I'm able to read analog input (temp sensor) from ADC0 with M0 processor, I would like to send information to M4 processor via Interrupts, DMA or something else, so that it can do something while M0 keep on reading.

Thanks in advice

Hello luca,

You can refer to the multicore demo under LPCopen, you can know how transfer data from the two cores.

Hope it helps,
