Posted on January 13, 2017 at 13:29Hi, i have problem, i can's understand, can i connect STM32F407 MAC(RMII) to MAC(RMII) KSZ 8863 without PHY level. In STM datasheet shown only RMII->PHY connection. I use lwIP lib, but it need PHY level. What can i...
Posted on January 15, 2017 at 21:27I am working with a Nucleo L031K6 board and my application showed strange behaviour that I could finally track down as two C variables sharing the same memory location....Not being a specialist in neither C nor the...

Posted on January 15, 2017 at 08:37Hello,I'm currently trying to write a library for the stm32f4 to output dmx via the uart. With other mcu's I've done this by generating the required start code etc by changing the port baud to a specific speed, sen...
Posted on January 14, 2017 at 14:30I have stm32 gpio pin connected through 5k resistor to the 12V supply. What voltage can I expect on the pin depending on the gpio configuration and processor model? Is there any internal clamping in the MCU?Do I ne...
Posted on January 14, 2017 at 20:38HelloIt is mentioned in the stm32f303vc that it's opamp GBW is 8, but as i measured in the lab, the opamp output (i tested opamp 1&2 in follower mode) can't follow a sine wave above 700KHz in frequency, i.e output ...
Posted on January 14, 2017 at 15:09Hi allI am wondering if I could use the 32K memory.If somebody know it, pls tell me how to do it.Because 96K bytes isn't enough for me.Thank you all in advance.
