| Aug 31, 2022 at 8:06 | comment | added | TonyM | @Frog, seems weird. OP will have MCU ('uC of ST'). You propose either an ADC chip or second MCU with internal ADC ('..use a discrete ADC or a micro with an in-board ADC'). MCU2 would need a program and so cost. But an ADC chip does not need programming as it contains no CPU, only registers for output data and possibly config'/chan-sel. (An ADC IC does not need 'programming' no more than a 74x Shift Register needs programming - there's no storage and no program in it. Like we don't 'program' a HDD.) Anyway, OP could use an ADC IC, select their ST uC MCU that has internal ADC or something else. | |

| Aug 25, 2022 at 16:04 | comment | added | TonyM | @user253751, a discrete ADC IC doesn't need programming. It just needs reading. | |
| Aug 25, 2022 at 13:56 | comment | added | Criticizing Israel not allowed | @TonyM can you explain how you would use an ADC here without programming? | |
| Aug 25, 2022 at 13:53 | comment | added | TonyM | @user253751, you've gone off at some tangent... | |
| Aug 25, 2022 at 13:46 | comment | added | Criticizing Israel not allowed | @TonyM A comparator doesn't need programming; a discrete ADC isn't useful for much unless you wire it up to a more complicated logic circuit. | |
| Aug 25, 2022 at 10:25 | comment | added | TonyM | An MCU would need programming though, while a discrete ADC doesn't. Why would you incur dev/manf/support costs and overheads with no return on that spend? | |
