Hi , I want to drive White Led 7 Segment Display. MCUs power supply is 3.3V (STM32F030C6T6), and white led voltage about 2.8V when the current is 20mA. So, light intensity is too low. Is there any way to increase intensity or need to use STM8S005C6T6 ?

Yes, we found it too. but the company rejected it because of the price. And they decided to use stm8.

Thanks for useful answers.
