Posted on May 11, 2016 at 13:01Hello. I made a code to send and receive data via USB bus based on the CubeMX CDC (Virtual COM Port).Now I can emulate one virtual COM Port with STM32F407VGTx Discovery Board, but actually I'm thinking if I can emulate...
Posted on May 09, 2016 at 06:15How can we get the timestamp information in a better way in ms - using systick configured @1ms and calling HAL_GetTick() to get the time in ms or using RTC? #systick #priority #!stm32f4-!stm32f401-!rtc #stm32f4
Posted on May 10, 2016 at 21:08The examples in the CubeMX repository do not use CubeMX to generate init code. This means that they may be a little useful for showing examples of on-chip and on-board peripherals working, but give little assistance i...
Posted on May 11, 2016 at 10:51Hello! Can anybody explain how to calculate SDRAM memory bandwidth, please? One example.
Posted on May 10, 2016 at 15:21I have to measure current and voltage rms as well as frequency for three phase sinusoidal. Is there an application note about measuring rms and/or frequency with the stm32f4 series? I 'm checking the specification and ...
Posted on May 11, 2016 at 12:27In the description of a break function of TIM1 there is the following statement (in 16.3.12):The break status flag (BIF bit in the TIMx_SR register) is set. An interrupt can be generated if the BIE bit in the TIMx_DIER...
Posted on May 08, 2016 at 11:07It is far from intuitive how to re-create the functionality of the CubeMX example or Application example programs using CubeMX. So why are they part of the CubeMX repository environment. For example, I am currently tr...
