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 new STM32H7R/S lines are built on the success of the STM32H7 series, offering even higher performance and security at a lower cost. The STM32H7R/S is a bootflash-based MCU powered by a Cortex®-M7 core running up to 600 MHz, with 64 KB of user fla...
Posted on January 25, 2013 at 01:05I have designed a custom board around STM32F407VET. I am using 8 MHz external oscillator (ABRACON ABLS-8.000MHZ-B2-T) with 22 pf load capacitors (CL) and 220 ohm REXT. When I probe OSC_IN or OSC_OUT pins using lo...
Posted on January 24, 2013 at 17:03Hello,I need to design a system which will compress a data with rate of 1000:1 minimum in the range of determined time.I want to compress data (tera bytes to gigabytes) and to save to SD card.I searched about open...
Posted on January 22, 2013 at 16:53 I am having some trouble setting up an external pulse duration measurement on a Timer. Ideally I'd like to capture the duration of just the first incidence of a pulse on the desired pin, but that could require ...
Posted on January 21, 2013 at 10:50having difficulty getting a custom bootloader working. Basically this is a MSD device bootloader, using USB MSD and SDIO Sdcard drivers and Chan FATFS. Note MSD only runs if there is not a valid binary file on disk...
Posted on September 01, 2012 at 05:25I'm running some ADC tests on a VLDiscovery board. The values returned for sampling the internal temp sensor and voltage reference seem to move around in surprising ways. Here's some data:> ADC samples: channel 1...
Posted on January 24, 2013 at 08:03Hello,I have been working with STM32F4 Discovery for a while. I haven't had any trouble before but I found some problems that I want to know why it happens. Currently, I'm trying to use external interrupt at 125kHz...
Posted on January 21, 2013 at 15:10Hello ; I have project where I have to record and play wav files simultaneously , but it is not clear in the datasheet of cs43L22 if that possibe or not ; Could anyone confirm that please if possible or not ? R...
Posted on January 23, 2013 at 17:28Today I update my STM32F0DISCOVERY ST-Link/V2 from version V2J14S0 to V2J16S0. I use an evaluaton version oh KEIL (version 4.60.0.0). Before the update I succeed in set breakpoints in my code. After the update I ca...
Posted on January 24, 2013 at 00:26I am using STM32F103RF chip, in the startup folder I see a full list of startup_stm32f10x_??.s files, which one is suitable for my case?
Posted on January 22, 2013 at 01:53Excuse me.STM32F103ZET6 is included in my board.Documents from internal flash is being used.I do not know what kind of flash. #stm32-internal-flash-kind
