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?

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
