Hi i am configuration UART1 as default and Tx pin switching into GPIO then reset (Low) the GPIO for 28 micro sec(delay) and set(high) the GPIO then again switching to UART1. during switching waveform level is intermediate as show in below. (my...
As, i am using stm32g474ret6 nucleo board, i try to generate a complimentary pwm signal with timer 1 (pin PA0 and PC13) it does generate properly it create a curve at the falling edge .now i change a variable and try to generate this wave of 200khz ...
Hi community people, As an introduction, please note I'm completely new to the STM32 world, and back in embedded world after a long break in the application level. I now jump in a new project that will be based on a STM32U5, and I start digging in do...
Dear Community,I'm working on STM32H743ZIT6 based project.Here I want to set up 4 ADCs which have SPI interface.On developer's forum is said "If all ADCs will be sampled at the same point in time with the same settings, then the SCLK, CS, and SDI can...
i am using a stm32f401ccu6 board to receive modbus rtu requests from a master device(windows laptop running simplymodbus) and prepare the response buffer and send itso far i can see that the response buffer is being prepared as expected in the live e...
Hello, After debugging for a customer, I have found that all ST H7 related reference manuals are simply copy/pasting old Synopsys IP settings of the USB HS and/or FS core from an ancient databook. The new driver for the H7RS is again a copy of an exi...
Hello,we are having an issue on the STM32H730 ; we would like to have a Timer Capture triggered by the USB OTG SOF signal. This should be straightforward since the USB1_OTG_HS_SOF signal is connected to TIM2 ITR5. However, we never managed to have th...
Hi everyone,I'm currently working on an STM32 project where I want to communicate with an SMBus-compliant battery (address 0x0B) using I2C. I'm using an STM32F105 microcontroller and I'm setting up I2C on GPIO pins B6 (SCL) and B7 (SDA). I've encount...
Hi I am trying to generate interrupt every 100uSec using Timer-2 using stm32f103c8t6 blue pill. I have simply set the system clock to 72 MHz pre scaled the timer two by 72 time using 72-1 and setting counter period to 100. I have also enabled TIM2 Gl...
STM32G071R8 & M95160-WMN6TP EEPROMWe have the DMA SPI TX direction working but are having issues with the data that is being returned. Technically this is a read from the EEPROM but the command and read address are sent first. The EEPROM responds wit...
