PB14 and PC9 of STM32G070RBT6 can't use PWM at the same time

[sunnyguhz]

I set PWM for PB14 and PC9 of STM32G070RBT6, but only one of them can work.
What can I do to make them work simultaneously?

void setup() { analogWriteResolution(12); analogWriteFrequency(10000); pinMode(PB14, OUTPUT); pinMode(PC9, OUTPUT); } void loop() { analogWrite(PB14, 2048); analogWrite(PC9, 1024); delay(1); }

Hi @sunnyguhz
This is normal:

Both pin used TIM1 by default.
Simply suffix one by _ALT1 to not use the same TIM instance

 analogWrite(PB14, 2048); analogWrite(PC9_ALT1, 1024);
