Resolved! SPI communication issue on STM32F103RB (sort of buffer over/underun)
Good day.I've got an issue when trying to connect two STM32 MCUs via SPI.STM32F429ZI is master and STM32F103RB is slave.Master is running at 168MHz and slave runs at 72MHz. SPI clock is the lowest possible - 164.062kHz.Slave select is hardware contro...
Looking for PVD example with STM32G0
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...
STM32L452 TouchGFX and SD Card
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...
Resolved! Different data after the 1st transfer using SPI via DMA (using LL Libs)
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.....
STM32F070CBT6 Emulate Eeprom Issue
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...
HID communication with classic USB library on STM32U5
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...
Resolved! PPPos Lwip Issue
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...
STM32H563ZI: implement USB CDC communication using ThreadX & USBX middleware
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...
