Posted on May 01, 2017 at 09:11Hi,i am using STM32L151 in our borad and for main clock source i have used pericom 8mHZ crstal and when i am trying to observe clock on scope ,i am unable see the clock.But SW team programmed the controller and with LE...
Posted on April 28, 2017 at 10:17Hello family ST,I would like to use stop mode with an interrupt Pin,I tried the PWR Stop example in STM32Cube_FW_L0,When I put the PA12 Pin to Vcc I have ?c wake up after it runs the program and so it resumes stop mo...
Posted on May 01, 2017 at 15:08I've implemented on my board the UDP packet server as a task for a board which has to support ethernet, but nothing is defined for the interface. So far so good. I send UDP packets to it and it receives and echoes th...
