Hello.I have a TIM3 configured to generate a PWM signal with frequency 1 MHz and duration 200 ns using CC1 channel. TIM3 also generates a DMA request on CC1.DMA1 is configured to transfer value 0xFFFF from AXI SRAM to SPI2_TXDR register, triggering t...
I use STM32L431 to enter STOP1 mode, the original power consumption is 53uA. Before entering stop mode, I call HAL_ADC_DeInit(&hadc1) to disable ADC, and call MX_ADC1_Init() to re-enable ADC after exiting STOP1 mode. The measured power consumption is...
Moved from https://community.st.com/t5/stm32-mcus/stm32-arduino-stm32duino-tutorial/ta-p/49649 After you have finished the arduino project, how do you then remove everything from the MCU and use it again for normal STM32 projects in CubeMX and so on?
Good morning everyone!I have a question regarding a USB to UART IC. I’ve seen that the FT231XQ is used in ESP32s to program and communicate via UART. Is it possible to do the same with STM32s?
I'm having an issue when using the DMA with SPI. I'm using the SPI for a 320x240 LCD and want the DMA to help with blocking while transferring large amounts of data with touchGFX.I'm able to paint the screen one color just using the SPI but when I t...
Microcontroller : STM32L476RG, External flash : AT45DB041E (4Mbit, 256 bytes of page, 2048 bytes of block),SPI2 communication protocol, using HAL.I am not able to use the LittleFS library in order to read a file that is written into the flash or any...
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...
I am new to Arm but old to assembly coding (inc Toshiba 32 bit CISC - now extinct).. Just completed RCC startup code for a STM32F344 chip by looking at the 1124 pages (!) of the RM0364 manual and the CUBE LL start up code (!!!). The CUBE code has wai...
I am using the Nucleo-H743ZI with a c++ project, and have used this code many times before with this board and c++; however, now the printf() function no longer prints to uart:int __io_putchar(int ch) { HAL_UART_Transmit(&huart3, (uint8_t*) &ch...
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...
