Analog to Digital Converter
Hi, I would like to trigger ADC conversion with GPT capture and compares events without using the FSP configuration. I couldn’t figure out how to do it, is there any example project about it? Thank you

The DA7212 supports 2 Digital mics on MIC1 channel and can support one Analog mic on the MIC2 channel.
The datasheet says that the ADC digital filter is shared for the analog/digital mic channels. So either the analog mic or digital mic can use this ADC digital filter
Can I get the Analog Mic ADC data to the I2S without using the ADC digital filter. If this is possible, then can I add 2 digital microphones on the MIC1 channel( I can do the digital filtering on the Analog mic in my firmware )?

You can use the AMIC and DMIC, however both will effectively go through the ADC filters. If you enable the ADC_FILTER1, which has the voice and music filters both paths (AMIC, DMIC), will be effected by the filters.

See lessI would like to know the level of Renesas RA2E1 ADC internal reference voltage. Is it fixed or adjustable? What voltage is it?

Hi dev , refer below link & download user manual hardware for RA2E1 & there is table given on page 1003 for ADC internal reference https://www.renesas.com/us/en/document/man/ra2e1-group-users-manual-hardware Thanks

Hello, It’s easy. see the section, 3 of the manual (RA4M1) To trigger the A/D, write to register ELSR8 (R_ELC. ELSR (8), and the number you write to that register is the event number shown in table 18.3, nearly between 0x57 and 0x96, depending on which timer, which event (and maybe which processor).Read more
Hello,

First, you have to enable the ELC registers by writing 1 to R_ELC. ELCR and writing to the module stop register.
You also have to inform the A/D by writing 9 to ADSTRGR (see section 35.2.12)
Thank You
