Posted on June 20, 2013 at 15:29Hi all, On my STM32F102R8T6 board, when the STM32 goes into standby mode, power consumption goes down to a few µA. But if I touch some pins of the STM32 with my finger or with a metal stick, power increases to severa...
Posted on June 20, 2013 at 15:05I recently extended the eeprom emulation code provided by ST to perform asynchronous page transfer when a flash page has no more space left. I need this feature because my embedded system runs in real time fashion (10...
Posted on June 20, 2013 at 14:18 I have found strange behavior of CPAL library when device is in slave mode. I use interrupt mode. When I'm waiting for read from master, I prepare data by: if ((I2C2_DevStructure.CPAL_State == CPAL_STA...
