Hello @SebB,
The SPI interface is compatible with the TI protocol. (which is the default case)
However, I inform you that STM32F4 has his own internal ADCs. In fact, you must know, the 12-bit ADC is a successive approximation analog-to-digital converter. It has up to 19 multiplexed channels allowing it to measure signals from 16 external sources, two internal sources, and the VBAT channel. The A/D conversion of the channels can be performed in single, continuous, scan or discontinuous mode. The result of the ADC is stored into a left- or right-aligned 16-bit data register.
Would someone have a external ADC that works with SPI TI mode to recommend?
You must choose your ADC regarding your application and what you are searching in terms of :
- Resolution (bits)
- Architecture (Delta-Sigma, SAR...)
- Number of input channels
- SNR
- Price...
Best Regards,
Pierre
