Posted on October 21, 2014 at 19:36The STM32L152VC includes an internal voltage regulator with contrast control from 2.60 to 3.51V. Those voltages then get used to drive the individual segments. In my case, I'm running the processor at 2.6V (VD). Wh...
Posted on October 15, 2014 at 10:14Hello all, Following some hardfault error with my code running into a STM32F415, I found a solution that leave me puzzled. In my main, I declare a array of 600 uint8_t called data;uint8_t data[600]; I call a funct...

Posted on September 24, 2014 at 09:37We have good experience with STM32f100, STM32F05x but for our new product we used STM32F030 and I am not able to program it over GDB. The interesting think is that F05x can be programmed over GDB without errors (...
