Hello,Now I'm developing on STM32L052T8Y6TR and thinking to occur every 20msec WakeUp from systick interrupt.More concretely, after Entering Stop Mode (by HAL_PWR_EnterSTOPMode), I want to start wake-up at arbitrary time. in the SysTick_Callback.I kn...

Hello,I tried to get temperature data from LM75 via I2C on STM32L0538-Discovery.But in following test program, HAL_I2C_Master_Transmit() and HAL_I2C_Master_Receive() returned HAL_BUSY.What's wrong with it?And I couldn't check from the schematic diagr...

HelloNow I use systick on STM32L0538-Discovery and I'd stop systick during RTC Power stop mode.Please show me hot to stop the systick and restart.Thanks

Hello,I  tried to EEPROM write/read test but it seems to not have written into EEPROM normally.My defined functions corresponding to EEPROM are like following.#define FLASH_USER_START_ADDR ((uint32_t)0x8008000)#define FLASH_USER_END_ADDR ((uint32_t)0...

Hello,Now I mean to measure temperature on STM32L0538-Discovery using STLM75DS2F via I2C.I saw the Demonstrations sample project but I couldn't see the proper codes for temperature IC using I2C.Are there any information, answers or sample project?Tha...
