Hello. I have set protection level 2 in stm32f407. Now I need to change the project a little bit, but st-link/v2 can't connect to the target. How will I able to reset level 2 and do 'mass erase' that chip?Thanks.

Problem calibrating MSI clock using LSE

Hello, I've been trying to calibrate the system clock of a Nucleo-64 board (STM32l152) using approach proposed in AN3300 to compensate the temperature error. The proposed solution works fine with HSI clock running at 32MHz. At room temperature the op...

Bluepill to STM32F446 with CAN Bus

Hi. I have developed a CAN based protocol to a Bluepill and now I need to test that on the Nucleo board as well. I have been trying this for a while now and for some reason CAN messages are generated from the Nucleo board. The code was working fine w...
