STM32U0 is the first Cortex-M0+ with a static consumption of only 160 nA in standby mode with RTC (Real-Time Clock) and 16 nA in shutdown. It also achieves 118 points in CoreMark and targets SESIP level 3 and PSA level 1 focusing on firmware code pro...
Hi,I am working with an STM32L476RCT6. On STM32CubeMX, in "Connectivity", I make use of the "USB_OTG_FS" functionnality and I have choosen the "Device_only" mode. In "Middleware", I use the "USB_DEVICE" in "Communication Device Class (Virtual Port Co...
I was referring to data sheet of the STM32G070 to figure out the current consumption of individual peripherals to finally calculate the power consumption of those peripherals. The following table from page 50 of the document gives those details. Rang...
Hi,I'm trying to control multiple PWM signals simultanously using DMA (used for controlling LED drivers). However I'm having an issue I can't seem to trace, one of the lines puts out an additional PWM signal cycle that shouldn't be there, this is wei...
I'm trying to build a custom HID device with the STM32F401RE board.I've got a basic keyboard recognized by my PC as a HID Keyboard from STM32_USB_training_course example as I expected, and "normal" key strokes works fine (letters, Enter, page up\down...
Hi,I wrote an external loader and tested for writing , erasing sector, erasing chip, reading, using "\testbinary1M.bin". But it failed in verification. What could be the reason? EDIT: I'm checkin what's going on by a logıc analyzer. I'm not using qua...
Hello,I developed a custom-designed system with an STM32F767 microprocessor and controlled its parameters with a user interface through a Bluetooth module. When I power off then power on the system, I couldn't communicate with the circuit board. Is t...
Hi I am trying to read ID of an external FLASH.The code which reads it is shown below.uint16_t FLASH_ReadID(void) { uint16_t tempData = 0x0000; //Read ID GPIOB->BSRR |= GPIO_BSRR_BR2; //Reset FLASH CS while(!(SPI1->SR & SPI_SR_TXE)); SPI1->DR ...
i'm trying to communicate with a Wifi module (esp8266) using STM32F103, on keil IDE. As described in the schematic : i want making my stm32 send AT command to esp8266 through usart1 (Tx1), and getting the esp response (Rx1), then display the esp resp...
Rev. 5 of RM0455 says "Reset value: 0x0000 4000" for PWR_SRDCR.However, the description "Bits 15:14 VOS[1:0]: 00: scale 3 (default)" contradicts this. And on actual hardware reset value is indeed 0x00002000.
stm32f429 Internal peripherals mmc 4.2，but present emmc 5.1。Is it a fully compatible driver?Is there a ready-made example？
