I'm very new to the STM32, so sorry if this sounds stupid. As far as I could understand looking at the datasheets, the STM32F407XX has 2 DACs, but when embedded in the discovery board an external DAC (CS43L22) is used. Why is that?
I'm using a STM32F429ZI Nucleo-144, and need a counter/delay function with 1 microsecond resolution, but want to keep the HAL_Delay function at 1 millisecond resolution for other uses.I'm looking at potentially reconfiguring the SysTick interrupt to ...
Posted on June 02, 2017 at 21:28I have a STM32F746NG Discovery board on which I have implemented a USB Composite device with MSC and custom HID classes. I also want to run Elm-Chan's FATFS to read and write files locally on the micro-SD card whilst ...

Hlello. I want to use single wire and half-duplex mode for spi master.Init works, and HAL_SPI_Transmit function works .But it will go to timeout when call HAL_SPI_Receive function from HALL. it still can't get RXNE FLAG . I measured it , it didn't g...
Posted on June 01, 2017 at 17:34Hello, I have some problems to implement a bootloader in a STM32F4. I searched on internet and I found coherent informations and examples, but I 'm not able to make simple test work.Here my simple code:bootloader (wri...
Hi,in order to reset my I2C sensor TLE493D-W2B6 A0 I need to send 4 bytes which consist of 0xFF->0xFF->0x00->0x00 . So no address or anything else, only the 4 bytes transmitted with 4 consecutive I2C accesses.Now I am using a slightly modified versio...
We're looking at using the F413 for a slave in a many MCU product, and using its SPI bootloader so master can reprogram an array of slaves over SPI. I'm confused about the bootloader and flash programming, in particular:(1) Is high voltage VPP and hi...
Hello Requirement is:we are using 3 cell(3.7*3 = 11.1V) battery in our design.so we are using charging IC for that.charging IC need 15v(max 2A) to charge LIPO battery.so we are going to use universal type c charger that Supports 5V,9V,12V, 15V an...
Problem: RTC Wakeup interrupt is not working on STM32L4 after calling the HAL_RTCEx_SetWakeUpTimer_IT.Cause:A preprocessor macro check rules out a call to the __HAL_RTC_WAKEUP_EXTI_ENABLE_IT for uC other than STM32L412xx / STM32L422xx in the file stm...
