STM8L156C6T6 - clock to gpio

Hi everyone,

I need to interface my ST with an external chip and I need to provide clock to this chip as well. Can someone tell me how to do it? I mean: is it necessary to use a GPIO or is there another way?

Thanks a lot,

Gilberto

Hello Gilberto.

STM8L152C6T6 (not STM8L156C6T6, which may not exists) microcontrollers can output a clock signal at pin 43 (PC4).

RM0031 ''STM8L05xx, STM8L15xx, STM8L162x, STM8AL31xx and STM8AL3Lxx microcontroller family'' provides more details on the Configurable Clock Output of this microcontroller.

PS: I don't know if you are using an external resonator.

If such is the case, you can also use OSC_OUT (HSE resonator: pin 4 - PA3) or OSC32_OUT (LSE resonator: pin 45 - PC6)
