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...
After writing some code for PLC01A1 and STM32 F446RE, I'm trying to port it on my F767ZI.PLC Board uses SPI PA5, PA6 and PA7 for CLK, MISO and MOSI, and F4 & F7 have the same pinout. In addition PLS01A1 uses F4's PB10,PB6 and PC7, but the same pins a...
When the MCU goes into stop mode 2, the VREFINT keeps drawing current. Is there a control register to turn off VREFINT when the MCU goes into stop mode 2
Hi all, I tried to configure the clock to run at 32MHz and I was using Systick to toggle the LED every 1 Sec by configuring the Systick reload value by 32Mhz -1. But, Somehow toggling is not happening for exactly 1 sec I also used a logic analyzer to...
Posted on March 24, 2017 at 03:57My MCU is STM32F205ZET6, and i want to use it to drive a external FRAM-FM22L16 by using the FSMC, but i have no idea to how to config the FSMC, also, I get confused about computing the ADDSET: address setup time,DATA...
