Hello, I would like to know if there are any special tricks to SPI half-duplex mode. As far as I know the configuration is done normally with only the direction as 1 line. Can anyone point me to some form of an example for setting up the SPI in half-...
I want to do ADC with 5 channels using STM32 Nucleo-144 development board with STM32F722ZE MCU.I can collect data by DMA, but I can only get data from in0~in2.Finally, I want to get ADC data from 5 channels at 1kHz using timer interrupt.This is my fi...
Hello and thanks in advance for reading my post. I am currently working on my dissertation, trying to implement a digital signing algorithm on a Arm Cortex-M0+ microprocessor. I'm using a NUCLEO-G0B1RE board with a stm32 with the same series. This bo...
Hi, I have written a custom bootlader which verifies CRC of the aplication and then jumps to the application. I wanted to know how can I check the total execution time it takes from start of the bootloader execution to the start of the application ex...
Hello I just purchased a STM32 board. Here is the link:https://www.aliexpress.us/item/3256807324905710.html?spm=a2g0o.order_list.order_list_main.5.3b001802nQFgBb&gatewayAdapt=glo2usaI ordered the Dual Channel version.Here is an image:How do I program...
Hello I want to understand Sequencer concept as per below link. https://wiki.st.com/stm32mcu/wiki/Utility:SequencerI tried to search stm32_seq.c in STM32F4 package but couldn't find. I don't see any sequencer folder under utilities folder.
Posted on February 21, 2017 at 04:53Hello everyone,I am trying to redirect printf() to ITM using the tutorial in https://www.youtube.com/watch?v=BwgPV3uKuzY and view the output. I followed the steps as shown in that video but I was unable to see the...
Hi guys, I bought a STM32F469I-Disco Board. I have played around with TouchGFX example projects and had success adding an ADC (ADC1_IN9 connected to Pin PB1) conversion to the project and display the value on the touch display as text in a textArea a...
Question the flash memory data retention is typically 30 years at 85℃ after cycling 1000 times(refer to the STM32 product datasheet for more information),and 15 years at 105℃ after cycling 1000 times,how did they get this result?Past experience?Ther...
Hi, I have the part STM32F405RGT6 with date code:2318 (does not have the ARM marking) and date code: 2440 (with the ARM marking) on the package body. Both coo: ChinaMay i know if anyone can advice or any PCN that support on this body marking changes,...
