Hello @danielholala,
You could check the "chip-specific ADC information" in the Datasheet and/or the User Manual of LPC553x. In this case, you could look the ADC Hardware Trigger information in the LPC553xRM.
For the number and sources of hardware triggers available, please go to:
- Section 46.2.2. Features,
[LPC553xRM. Chapter 46. Analog-to-Digital Converter (ADC)]
- Section 46.1.4. ADC trigger inputs, and
[LPC553xRM. Chapter 46. Analog-to-Digital Converter (ADC)]
- Section 14.5.1.22 and 14.5.1.23. ADCx Trigger input connections.
Best regards, Raul.
Hello @RaulRomero ,
Thank you for getting back to me.
Let me please repeat in my own words what I learned from your notes:
Using "INPUTMUXER" registers, I route up to four trigger sources to each ADC (e.g., via registers ADC0_TRIG0 - ADC0_TRIG3 for ADC0) selecting from 35 trigger inputs for each trigger source.
Then using "ADC" registers, for each trigger source that I routed above (up to four), I configure the ADC command that is triggered by that trigger source (e.g., via registers TCTRL0 - TCTRL3).
That's different to the LPC552x with regard to routing trigger sources using the INPUTMUXER is not available on the LPC552x.
Did I understand this correctly?
Cheers,
Daniel
PS: You seem to be looking at a different version of the manual than me. This is what I'm looking at: Rev. 3, 07/2023
https://cache.nxp.com/docs/en/reference-manual/LPC553xRM.pdf
and there the ADC section has been moved to chapter 47:
PPS: If the reference manual could be a bit more elaborate instead of trying to be as concise as possible that would help and I would not need to raise these questions here. Nevertheless, I appreciate all the help I receive through the community forum. Thanks.
