Posted on May 11, 2016 at 12:30The Application Note doesn't seem to consider the case of a Repeated Start Condition.Are there any special considerations?Although the App Note specifically addresses STM32F10x, I am actually using an STM32F411 - See: ...
Posted on May 05, 2016 at 19:13Folks, I have code for using the F103's USB device port as a virtual com port. Does anyone know: 1. Could I use that ''as is'' on the F107's OTG port. I only ever want to use it as a device. 2. Do I really have to hav...
Posted on May 12, 2016 at 17:53 Hi, I need a custom DFU bootloader. I started from the one given as example with Cube 1.5. It is located in STM32Cube_FW_L1_V1.5.0\Projects\STM32L152D_EVAL\Applications\USB_Device\DFU_Standalone ...
Posted on May 11, 2016 at 15:43Hello, I use the HAL EXTI callback function on an STM32F411 and have made the following strange experience: When changing data types from float to uint64_t for Efficiency in another callback function (actually from DMA...

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 ...
