It has become my habbit to place pulldown resistors on inputs/outputs. This ensures that pins are not floating and are pulled to GND to a known state.Normally, this wouldn't be a problem but since I am working on ultra low power battery powered devic...
Hi All,I am working on a Dynamic graph widget on the STM32F7 board. Below is the configuration of my setup.1. Controller: STM32F756ZG 2. Display: Waveshare 7" LCD with 800x480 resolution3. External RAM: SRAM 8 MByteI have attached the project and vid...
I am designing a custom board using STM32F446RE as main MCU and STM32F103CBT6 for ST link. I am using MB1136 board schematic as reference. I have the following questions:1) Should I connect NRST of pin of main MCU to ST link MCU? But in reference sch...
vorrei utilizzare un'interfaccia grafica per visualizzare i dati di accelerazione e per utilizzare MLC sulla scheda STM32WB
Hello, I tried to use the go Command at the beginning of flash (0x08000000), the bootloader sent me back an ACK. But i've got 2 problems. First, if i don't change back my boot pins, i will be in System Memory Mode, why ? Am I reading boot pins at the...
Hi,I'm using an STM32F407VGT6 at 168MHz, SPI3 clocked at 21MHz (the SPI1, which does up to 42MHz is in use elsewhere).I did some tests with the SPI ILI9341 display 2.4" of 320x240 pixels, and to fill the screen completely using HAL_SPI_Transmit() tak...
I'm new at STM32 MCU.Is it possible that on STM32MP157D-DK1?I first set a value to DAC and then use its output as input to ADC then finally get a digital output which must same as the value i set to DAC. (Without DMA)If I can do that , how can I do t...
Hello All,The above function is used to config various clocks. For the RTC it contains this /* Enable Power Clock*/ __HAL_RCC_PWR_CLK_ENABLE(); /* Enable write access to Backup domain */ PWR->CR |= PWR_CR_DBP; // Wait for above to stabi...
I have the following setup: Master<---------I2C------------>STM slaveThe master communicates like this:1) Master I2C write: [Start bit, I2C address (from master)], [Req Data1 (from master)]2) Master I2C read: [Start bit, I2C address (from master)]...
The code runs perfectly fine, and as expected when I don't have a USB connected, given that I push the Reset button (B2) on my Nucleo-F746ZG.The problem is that when I remove power from the system, and re-power it, it seems to not reset. I have jumnp...
