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...
The STM32 families typically use Quad-SPI for executable external flash, from my research (ref)But the only H-Series options with Quad-SPI are expensive! Are there any alternative methods to executable external program space?
We have product that runs on two AAA batteries based on STM32L010K8 and according documentation this product should consume around 26uA when in low power run mode(32Khz clock source).Measurement showed that micro consumes around 90uA which is unaccep...
hello everyone, I have been trying to display even basic text on my TFT 1.8" Display and am yet to get anything but gibberish. I am using this library to interface with it. https://github.com/afiskon/stm32-st7735 I have followed plenty of tutorials...
After trying the sample code from STM32Cube_FW_L4_V1.18.0 for octo spi I getting stuck on HAL_OSPI_AutoPolling(hospi, &sConfig, HAL_OSPI_TIMEOUT_DEFAULT_VALUE); it is not working, after reading posts and STM32L4Rxxx and STM32L4Sxxx device errata I fo...
Posted on May 09, 2018 at 22:36I am using STM32L051 mcu. The mcu goes to STOP mode after initialization and only wakes up if there is any incoming byte at USART1. MCU wakes up with START_BIT_DETECTION on USART1 and goes back to sleep after it receiv...
Hello, I am currently fiddling around with a STM32G491 in bare metal. I wanted to test the write protection. So I executed following code FLASH->KEYR = FLASH_KEY1; FLASH->KEYR = FLASH_KEY2; while(FLASH->CR&bit31); // wait for unlock...
Greetings! We have custom board based on STM32F745VGT6 having Ethernet peripheral over RMII mode.Previously with the older version of Cube MX and Library our Ethernet was working, after the new update of library there are some major changes in the li...
Dear all,I am writing a bootloader and I experienced that the calculated CRC on the binary is different If I load the fw with cube IDE versus cube programmer. I use STM32F405.This happens too if I make the compairement on the bootloader programme too...
On the H743VIT6 I am seeing a strong spike on the VDDA line every time the 32 samples are completed and DMA triggers to copy them to memory.This is causes the samples to have a 1500 Hz signal with 4 harmonics in the data.The board is 4-layer, solid g...
