About STM32F072 device , Problems when use HAL_SPI_Receive function of HALL in single wire and half-duplex mode.
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...
Resolved! Problems with custom bootloader on STM32F4
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...
I2C send 0x00 and 0xFF for sensor reset
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...
Resolved! Confused about F413 flash programming and bootloader
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...
How to set required voltage on STUSB4500 IC
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...
RTC - [STM32CubeL4][1.13.0][stm32l4xx_hal_rtc_ex] Missing EXTI interrupt activation
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...

Hello,I created UDP server with LwIP stack on STM32F407.I tried example udp_echo _server. It works.Now I need send from server my own answer data in callback function.The program hangs in callback function.void udp_echoserver_receive_callback(void *a...
how to switch between HAL_SPI_Receive_DMA and HAL_SPI_Transmit_DMA ?
to develop a SPI full-duplex dma communication, I use an stm32L4 as MASTER and an stm32L0 as a slave.firstly to check if the slave is ready, master send tram "is OK", the slave receives the trame and if he is ready he sends tram "ok".After when the m...
