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 February 12, 2014 at 14:42Dear all, I am using the STM32F429i-Discovery, and I experience some problems with UART communication: received symbols are differents from TX. Discussing with some colleagues points out the baudrate might be in ...
Posted on February 13, 2014 at 22:59Hi forum!Here is a very strange problem I'm facing with the SPI1 peripheral of the STM32F417 connected to the LIS3DH. I have to single-step through my code with my debugger in order to get the right data from the ...
Posted on February 08, 2014 at 20:52I'm currently testing I2S between two F4 Discovery development boards.One board is master, running DMA, one is slave. Both are configured with the same sample set for verification purposes, so the data sent can b...
Posted on February 13, 2014 at 22:30Hullo , ...... Im working on Waveshare board (PORT207Z) , it has the STM32F207ZG chip , I can use the simulator debugger properly , but when I use my J-Link debugger , debugging does not work properly , it says (J...
Posted on February 13, 2014 at 14:07I've set up my DMA to transfer 106 half-words via the SPI to a memory buffer. I am quite confident that my buffer size is correct. However, when the transfer actually occurs, it is twice the size I expect (and is ...
Posted on February 13, 2014 at 20:30Hello, I am working on the STM32F429 with Keil uVision version 5, and am trying to get the USART1 module working. In attempting to use the functions provided in the stm32f4xx USART library files, I am getting very...
Posted on February 13, 2014 at 14:00I use stm32f4-discovery board. I am working with the ADCs, and for my prpose I need to set the ADC reference VREF+ at 3.2V. in the reference manual RM0090 it is said that stm32f4 LQFP100 has VREF+ VDDA pin. But th...
Posted on February 12, 2014 at 18:03I'm using custom code which is somewhat ported from the STM3240-G USBD-MSC example application. I also made modifications to the read/write functions to take blocks as arguments vs. bytes. I've stepped through the...
Posted on February 13, 2014 at 14:11Hi all,I'm using stm32f100c8 with an external oscillator 8MHz to produce a system clock of 24MHz. All the peripherals are on the default division lines.Now the ADC1 which is with the TIM1 on PCLK2 is supposed to r...
Posted on February 10, 2014 at 10:39HiI'm using STM32F373x SPI in slave mode. I get errors in about 0.1% bits transmitted, occurs in 50% of units from first production series of custom board. SPI lines have RC filter installed to improve EMC immunit...
