Posted on March 08, 2017 at 00:10Hi,I am using an STM32F103 connected to an I2C device. I can see that the device is responding to 2 ranges of addresses, one mapped to registers, one mapped to an EEPROM address space. I can communicate with the devi...
Posted on March 21, 2018 at 09:00I have tried to use SWV on DISCO-Board STM32F746 with Firmware V2J30M19. It does not work. But it works with Firmware V2J29M18.On Nucleo STM32F746 SWV work with both Firmware versions.Is this a common problem?
