Have just purchased a F769I disco board and upon powering it up both by the USB stlink connector with the stlnk power jumper enabled and a PoE injector with the poe5v power jumper enabled, the board has the "PWR" LED lit and the "COM" LED is blinking...
Hi,I need to test power consumption on NUCLEO-L432KC with UART working on high baud rate. I've removed SB9 and SB14 to do so. Board is powered by external 5V source. While trying to flash following the Chapter 6.4.2 (External power supply inputs) fro...
hi all, I am using STLINK/V2 ISOL which says ST_LINK, No MCU device found, just replacing with STLINK/V2 works keep all setup intact.what could be the reason.
Hi,I am currently optimizing some designs and started thinking about decoupling capacitors. As far as I know, it is a rule of thumb to place "one 100 nF capacitor per V+ pin".In the attached document, ST recommends exactly this. Let´s look at the doc...
I have been working with the STM32747i-Disco and the STM32F769--Disco boards. Both have the MB1166-A09 LCD daughter board attached. I have implemented the LCD_DSI_CmdMode_DoubleBuffer example for both. Teh H747 platform took a little more work as the...
I have two of the STM32H747I-DISCO boards. I have used STM32CubeIDE to create a simple project for the boards. I followed AN5361 and am able to debug and see the CM7 and CM4 cores running.I've added code to toggle the board LEDs (port I) but don't se...
I am trying to send data over I2C3 Using STM32F429 Dev Board and Everyting works fine except the HEX Data I want to sendI am Passing this function HAL_I2C_Mem_Write(&hi2c3,0x30<<1,0x09,I2C_MEMADD_SIZE_8BIT,0XFF,1,100); And Getting the Following Outpu...
I have been using stm32f429 Discovery board for a while. recently i tried to use it for programming a blue pill using onboard St-link v2. But it wasn't working even though all connections are okay. Later i figured figured out that target VDD pin whic...
Hi, I need your help in order to get running on my board "NUCLEO-F767ZI" a Web server....Thank you in advanceDaniel julio Abad
Hi,I'm working with power amplifier for which I have chose stm32f407 controller which monitors ADC, I2C eeprom SPI Flash memory, ethernet , GPIOs and interrupts. when i am doing code development and standalone testing of controller no issue of hard f...
