I 'd like to use a GPIO of STM32 to generate a clock for other peripherals. This clock should have the same precision as HSE.Also, the clock should be stable.Also, once set successfully, its stability is not disturbed by running code/interrupts.And i...

I need to use the I2S of uC to communicate the Codec with the full duplex mode.Can I use the two half-duplex I2S in STM32F07X (e.g., STM32F071CBT7TR) to get that? I know that in the STM32F4 series, this function can be achieved with two half-duplex I...

Thanks . Maybe MCO is the best option. Can I expect a more general solution?Using HSE as clock source, route to a GPIO through PLL to generate the required clock.:grinning_face:

Okay, I will look for it .

Thanks，But why modify the SPI/I2S resource for this functionality in the STM32F4x family?(The means of provision can be internal connect I2S_SCK, I2S_WS of 2 I2S together)In my opinion, Other than that （ connect both clocks externally）, STM32F07x ...

How do I generate a clock for other devices using STM32's GPIO

Can I get the reference design about STM32F401X ?

Merge the two half-duplex I2S in STM32F07X to 1 full duplex I2S
