Posted on December 06, 2015 at 11:57Hellousing MDK-ARM , I want from startup code change the initialization of global variable after warm reset (Pressing reset button) ... But I dont know where to look ?The idea is I want the variable keep its value...
Posted on December 03, 2015 at 17:15Hi All I can see a drive is attach when i plugin nucleo to my mac. If i unplug it and plug it in again, no drive is mount. How to fix this?thanksfrom Peter
Posted on December 07, 2015 at 04:02For the Chip STM32L151RBH6, we have only 1 bank, EEPROM writting halt the MCU. I make a test program to repeatedly write EEPROM. Use the code like below to write EEPROM: *(__IO uint32_t *)addr = data; 100 times r...
Posted on December 06, 2015 at 10:30I tried to copy some code from STM32F series, and make some change to let it run on STM32L151. But it doesn't work on my STM32L151RBH6 chip: code as below:int main(void) { /* System clocks configuration -------...

Posted on December 04, 2015 at 19:22Hi, In a goal of a personal project, i am trying to profile energy consumption of an ARM MCU board, so i take the ''stm32F407 discovery kit'' as an experiment example.In my power measurement experiment i always ge...
Posted on December 04, 2015 at 16:46I am working on a Nucleo152RE using EmBitz. The code generates a PWM signal (200Hz 50% duty-cycle) on PB8 (TIM4 channel 3) (It works, I tested with an oscilloscope), then gives this signal as input to PC6 (TIM3 ch...
