Posted on April 30, 2018 at 10:52Hi,I have a MAX17205 Fuel Gauge connected to an STM32373C-EVAL board over I2C. I'm trying to read the DEVNAME register on the MAX17205 as a communication test but am getting a NACK error. I've checked the I2C signals...
Posted on January 31, 2018 at 13:44Hello! I've found a bug in RTC adjustment, when I used STM32CubeMX 4.24 for STM32L0.MX_RTC_Init does not activate RTC because of HAL_RTCEx_BKUPRead/HAL_RTCEx_BKUPWrite 'guard'. For example, 4.23 version did not wra...
