hello! i have a question about the power voltage detector in (external input analog voltage) i have a adjustable power supply connected on the pin (using a nucleo-G0B1RE) i was thinking that if i drop the voltage on the pin under the vref int voltag...
Hello,I am using a custom board with the STM32L452RET. On this board:SPI1 is connected to an IIS3DWB accelerometer,SPI2 is connected to a 240x280 TFT display with an ST7789 controller and TouchGFX,SPI3 is used with FatFs to access an SD card, followi...
Hi everybody.I'm facing a strange behaviour on my application. I'm using a STM 23H562, and I'm usign LL library to drive a SPI display (classic iLi).I take the example from c:\Users\[..]\NUCLEO-H533RE\Examples_LL\SPI\*and the display do what I want.....
When using this microcontroller for emulate eeprom process, i got some problems like freezing at start-up, when writing OLED, sprintf function can not write characters- writes silly words. I am not sure if the problem is about my emualte_eeprom proce...
Hi everyone, I am trying to implement HID communication using the classic USB library on the NUCLEO-U5A5ZJ-Q. Until now I tried to follow this tutorial https://community.st.com/t5/stm32-mcus/how-to-use-stmicroelectronics-classic-usb-device-middleware...
Hello everyone,Today I'm writing to you because I'm trying to implement a PPPoS connection over the USB CDC Host of a STM32H745. The modem I'm trying to connect to is a SIM7500 of SimCom.I managed to establish the connection between the modem and the...
Hello STM32 community!I'm relatively new to the embedded field and have been diving into communication protocols through small projects. Currently, I'm working on implementing USB CDC on an STM32H563ZI, and I've been facing challenges for the past tw...
HiI'm using this example:en.stm32cubef7_v1-16-0\STM32Cube_FW_F7_V1.16.0\Projects\STM32F767ZI-Nucleo\Applications\LwIP\LwIP_HTTP_Server_Netconn_RTOS\EWARM(I have applied patch 1.16.1)I'm using a Nucleo-144 STM32F767ZI.The board has a static IP address...
I cannot get OTG_HS to communicate with a USB host, and I'm out of ideas. Any help would be greatly appreciated.The problem:I've instrumented HAL_PCD_IRQHandler to print whenever an interrupt occurs. Right after USBD_Start, I get:0x800 (USBSUSP)0x100...
Hello STM32 community,I am currently working on an embedded application using the LPTIM1 (Low Power Timer Mode) on an STM32WL55JC16 microcontroller. My goal is to count pulses from an external signal connected to the BP5 pin (assuming this is the cor...
