A brand new Nucleo F767ZI. Plug in USB cable to the ST-LINK usb connection on the board. The Red "com" led comes on steady for about 1/2 sec then begins blinking several times per sec. No other LEDs on. I find the not/pwrEN line from the ST-LINK ...
Hello, i need to develop a board with stm32f103c8t6 mcu wich can communicate with an other stm32f103c8t6 using the usb.I'm studying cdc and i can create a simple program that communicate with laptop through "putty". I can transfer data from pc, recog...
Hallo,My board is the STM32F746ZG Nucleo board.I am using the LWIP_HTTP_SERVER_NETCONN_RTOS example from the stm32cubef7 package.The example works fine initially but if I leave it running for several hours suddenly the board stops responding in any h...
Sorry for my bad englishHi.I use STM32H743ZI and develop firmware.I put an example of a lwip tcp echoserver in my firmware.Example: STM32H743ZI-EVAL lwip tcp echoserver applicationI'm not using RTOS.My question: Ethernet operation relies on build opt...
Hi,I want to send 2-bytes from I2C in a single transaction with std peripheral library. For 1-byte i can handle with code below, but how can i send 2 bytes ? Any advise ?void I2C_Write_Byte(I2C_TypeDef* I2Cx, uint8_t reg_addr , uint8_t reg_data, uint...
@I am using STM32L152RE Nucleo board for my development. My goal is to bring up a PPP connection using LwIP stack in a FreeRTOS environment. The evaluation board I am using does not have an Ethernet port. I will be talking to the modem serially. Cube...
They are meant to be on the product page with the CAD drawings and IBS files but they are missing.
@Hi Team,I want to play audio clips over I2S like short audio clips - Connected to device , Disconnected etc, so. I converted .wav file to C- code (Im using WAVtoC software to convert C-code)and stored in flash memory. Below I attached the .wav to c...
Hi, I am using Nucleo F303re with STM32 HAL Libraries built by STMCubeMX in order to implement an USB Audio player with bulk transfers. I changed the USB-CDC code a little bit to implement my application. I receive the data in the CDC-Receive-FS func...
Hi All, I'm having trouble understanding a caching problem with the STM32F7. In the ExtMem_Boot example the code calls SCB_DisableDCache() just prior to jumping to the application stored on the external QSPIFlash . However it never returns from t...
