Posted on June 14, 2016 at 22:54Hello,Where can I find info on hardware needed to run USB to my STM32F072CB? I found the reference design and read hardware getting started. Neither specify how to get USB levels down from 5V to uC VDD. 5V can't go...
Posted on June 15, 2016 at 18:33Hello, We would like to read hal sensor outputs(H1,H2,H3) of bldc motor by xor gate of TIM4 channels. We select SLAVE mode for RESET MODE to read number of squarewave of xor gate outputs of TIMER4 but it does not wor...
Posted on June 15, 2016 at 17:44Hello guys, I'm trying to install u-boot on my development board STM32F407 . After loading the binary image, the UART1 interface does not work . I'm using the version available from the website emcraft for the board S...
Posted on June 14, 2016 at 21:16Hi all,I have a design based on the STM32F405 working, I would now like to try out the STM32F415, is it the case that on the hardware side I can just replace the STM32F405 on PCB with the STM32F415 - given that...
Posted on June 15, 2016 at 08:26Hi, In STM32F105xx datasheet, in part numbering section, it has an option named ''Software option'', and it has two options: internal code or black. What does it mean? #!stm32 #part-numbering
Posted on June 15, 2016 at 16:03Hi, I made a loader with usb STM32F105 and working properly. When I active the read protection bit, the loader not erase the pages. The security bit is on and of course, I can not debug and find where is the problem. ...
Posted on June 15, 2016 at 15:50Hello all, I'm facing an issue with sending commands (and time-stamp) from PC to MCU (Stm32L151) via USB_VCP. Following the idea from http://www.instructables.com/id/Synchronise-DS3221-RTC-with-PC-via-Arduino/?ALLSTEP...
Posted on June 14, 2016 at 16:31I am using NUCLEO-L11K4 board for my low power monitor project. I want to wake up board periodically every 5 minutes and send message center. Meanwhile i want to wake up the board with external interrupt in the case o...
Posted on June 15, 2016 at 00:58 Hi I have written a small proeject where I have set up an STM32F407 on a discovery board as an I2C slave, and I'm pleased to say that it is mostly working. The problem I have is that when I send the follo...
Posted on June 14, 2016 at 17:32 Hi everyone, I'm quite new in the world of stm32 and microcontrollers in general. Here is the thing: I want my f334 to generate a sine waveform which is going out by the DAC. I want it to adapt the fr...
