Posted on July 17, 2017 at 17:09Hi,i have multiple slaves on an I2C bus on STM32F4. Since a 'I2C_HandleTypeDef hi2c_x;' contains also fields like 'DevAddress', do i need one HandleTypeDef per slave device on the bus or should they share one handle? ...
Posted on July 18, 2017 at 11:00Hi all,For a project we have to update the firmware of the STM32F469xx over the air by a Bluetooth connectionwith a transmitter (can that be a smart phone?) and receiver on the microcontroller device part.In an articl...
Posted on July 15, 2017 at 00:48Our tech managed to mount a '407 180 degrees out. We figured out that it was because there is a molding mark 180 degrees from the pin 1 mark and they really aren't that different.Why not use the pin 1 mark as the inje...
Posted on July 07, 2017 at 08:06Hi,I use a STM32L4x6 with CubeMX 4.21 FW1.8.0 as a USB device. At some points I want to put the MCU in STOPx-Mode.How do I prepare the USB-Stack before entering STOP-Mode ?Regards.
Posted on July 17, 2017 at 16:17Hi,I'm developing a bridge USB-SPI with a STM32L052 microcontroller. In this starting moment I'm developing the same application using the evaluation board STM32L073RZ. I'm using SW4STM32 IDE and STM32CubeL0 software....
Posted on July 14, 2017 at 03:30Hello, I'm using STM 32 ST-Link Utility to program my MCU. I want to make sure that when I program the board multiple times I don't erase the data saved in a particular page on memory? Can I do that? If so, then pleas...
Posted on July 18, 2017 at 05:08Hello, I'm new with STM32 and this is the first time for using I2C on STM32.My environment is Keil5+cubeMX4.22.I can make the config by cube and I wrote following code, but couldn't compile it.uint8_t c[5] ={'a', 'b',...
Posted on May 16, 2017 at 17:08Participated in the webinar from the ST Microelectronics broadcasted emails. Invested most of the hour listening through the Milli Vanilli reborn presentation on how to use the AWS with the new STM32L4 IOT Discovery Ki...
Posted on July 17, 2017 at 17:41Hi why is ST releaing example projects for IAR but not system workbench? Is there a way convert this IAR project to system workbench?https://my.st.com/content/my_st_com/en/products/embedded-software/evaluation-tool-so...
Posted on July 17, 2017 at 07:01heyI'm use stm32f013cbtx and 8MHz crystal connect to HSE And use standard peripherals library with Keil v5.How can i config micro-controller for 72 MHz clock(with Cmsis)?is it possible?Thanks
