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...
Hi,Processor : STM32f429Frequency :180 MhzFatFs : ChanIn my project, I am copying the files from the SD card to the USB stick.I having the problem with copying speed. Currently a 45 MB file copies in 1.55 minutes.How to improve Speed? What are the pa...
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...
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...
Issue with the customized board is that, it does not detects USB(FS CDC) comport every time as we plug/unplug the device.whereas the same firmware works fine with ST nucleo board of STM32F070RBTx.1. Do programmer needs to add any additional delay for...
