I have developed the custom board for stm32F103 series. now i want to replace F103 series with L07 series. i am using Arduino IDE and STM package

[Tesla DeLorean]

Ok, is there a question in there somewhere?

[TVard.1]

I have 2 copy of PCB ,one with stm32F103 and other with stm32L071. The stm32L0 doesn't work! By looking at datasheet both have same pin compatibility.

Do stm32L0 require different crystal oscillator?

What exactly doesn't work?

Blinking a LED works?

Blinking doesn't work!

How do you program the L0?

Show us the LED blinking program.

[TVard.1]

void setup() {
  // initialize digital pin LED_BUILTIN as an output.
  pinMode(LED_BUILTIN, OUTPUT);
}
 
// the loop function runs over and over again forever
void loop() {
  digitalWrite(LED_BUILTIN, HIGH);   // turn the LED on (HIGH is the voltage level)
  delay(1000);                       // wait for a second
  digitalWrite(LED_BUILTIN, LOW);    // turn the LED off by making the voltage LOW
  delay(1000);                       // wait for a second
}

PC 13 is the default LED pin.

i got PWM working on only pins which are assigned in Thunderpack . https://cdn.hackaday.io/images/7315331605831459582.png.

pin like PA15 or pin which are not assign in this board are unresponsive.
