Porting STM32F1 Firmware to STM32F4
Hey all, I want to port this https://github.com/ArduCAM/STM32/tree/master/STM32F103 package to use for an STM32F446RE development board. Can anyone offer any advice as to the best practices of accomplishing this? Would it be modifying mapping of GPIOs, c

ADC - conversion time 계산
Conversion time
According to the datasheet, the total conversion time is calculated as follows:
Tconv = Sampling time + 12.5 cycles
Example: With an ADCCLK = 14 MHz and a sampling time of 1.5 cycles: Tconv = 1.5 + 12.5 = 14 cycles = (14cycles/14MHz) = 1 µs
There is an entire article on the Conversion Time and Frequency calculation. You can read it
https://controllerstech.com/adc-conversion-time-frequency-calculation-in-stm32/
How to calculate ADC Conversrion Time and Frequency in STM32
ADC Conversion Time = Sampling Time + 12.5 Cycles. Here Sampling Time is something that you can choose during the setup in the CubeMX.

응용: STM32F107 , ADC clock:
- ADC clock : 12MHz
- 5.1 (Typ)~ 17.1(Max) us
- 5.1us , ADCCLK=12MHz, sampling time of 5.1us: Tconv = 1.5 + 12.5 = 14 clcyes = (14cycles/12MHz) = 1.16us
