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...
Posted on June 27, 2017 at 22:08I developed the code for my application using Nucleo F446Ze. I use CubeMX and gcc on macOS. All works fine.Next I want to develop my own PCB with the same processor. Thinking ahead to how I will flash it, I broke off ...
Posted on June 26, 2017 at 16:03Hey,I have a problem with the I2C1 on the STM32F746G-Discovery.I'm using the example-code for communication with DMA, but I changed the address mode from 10bit to 7bit.Now it's getting strange. The ST-Board is the mas...
Posted on June 27, 2017 at 14:45Can OSC_OUT pin be used as GPIO pin when OSC_IN is used as clock input ?CubeMx shows that both of OSC_IN/OSC_OUT should used as clock pins with HSE(bypass clock source) options.
Posted on June 26, 2017 at 08:34Hello, I am developing an entertainment firmware for a custom board that mounts an STM32F469 microcontroller. This has 2Megs of FLASH and I would like to do something 'unusual' with the memory use. My idea comes from ...
Posted on June 27, 2017 at 13:33HelloI am working on STM32F405. I need to detect falling/rising edge or high/low pulse using timer capture mode. Basically I am trying to interface an IR remote which works on RC5 protocol with STM32. But before that ...
Posted on June 26, 2017 at 15:25This is my first experience with USB as virtual keyboard.I have configured in CubeMX a Human Interface Device (HID). After that, to have someting written in my notepad I have written the following function: uint8...
Posted on June 27, 2017 at 10:02hi everyone,i�m working with the STM32F051.I want to programm the System memory over the Serial interface using the ST Flash Loader Demonstrater.So i set the BOOT0 Pin high, and connected the STM32F051 to the Computer...
Posted on June 27, 2017 at 16:06With our custom board (STM32F103) i debug with Segger J-Link. No Problem with 'WFI' instruction.Now i tried to use ST-LINK/V2 with latest firmware (2-28). Download and single step actions are ok, but in run mode the a...
Posted on June 27, 2017 at 13:57I am controlling the M24SR from a STM32F030R8 over I2C, trying to configure it so the GPO pin is triggered by the SendInterrupt command over RF. I have been working from the example code given http://www.st.com/en/eco...
Posted on June 26, 2017 at 17:14Hello,the STM32H743 datasheet is out. I think the datasheet disaggrees on 'Max timer clock'. Table 4 in footnote 1 tells that 400 MHz is possible depending on the TIMPRE bit, while electrical characteristics 6.3.31 T...
