Posted on June 27, 2018 at 05:32Hi Everyone,I am working on I2C to sense DAC data. I generated the code using STM32CubeMX. It gives timing in hex format i.e.'hi2c2.Init.Timing = 0x10707DBC;'. It does confuse me that how does it calculate timing ? I ...
Posted on May 03, 2018 at 17:29I am trying PIL in simulink with Nucleo board with stm32. But everytime there is error with crating some file. Does somebody has similar issues? What can be wrong? Simulink model I used is attached. ### Copy algorithm...
Posted on June 26, 2018 at 14:03I am asking this because when referring to the Reference Manual I see that the vector table resides at addresses 0x0000 0000 to 0x0000 00BC:and the end of the table:But if I go the the linker script file I see that th...

Posted on June 27, 2018 at 07:33Hi,For an application we need a bulk of digital inputs(comes from sensors- about 30 inputs) and a bulk of digital outputs(go to relays- about 15 outputs). which solution would be better?1- using a high count digital i...
Posted on June 27, 2018 at 12:01I would like to power my STM32F446RE with an external source instead of using USB. Can I simply switch the position of JP5 such that it is connecting the E5V pin and the middle pin, and then provide the supply to the ...
