Posted on August 25, 2016 at 19:58Hi, i'm using your CubeMx to generate code of USB Host.Code work, but when i connect a keyboard logitech with 2 Endpoints ( 0x81 and 0x82 ), the second endpoint not work ! Endpoint 1 is used for normal keyEndpoint ...
Posted on August 25, 2016 at 09:59 Hello, I am using the board Nucleo-L476RG, the system core clock is running at 80 Mhz. I don't understand what is the purpose of ClockDivision. I thought that I can divide the frequency by 4 if I setTIM_CLOC...
Posted on August 23, 2016 at 19:58I created a project with STM32CubeMX, generated the source code (for MDK-ARM5), then expanded my code by adding a couple of new source files.Later, I went back to tweak my original Cube project and when I regenerate...
Posted on August 25, 2016 at 07:42Hello everyone, i have a st32F407 and i was thinking if it is working on 3.3V and almost all its pins are 5V tolarant what kind of protection circuit it has for overvoltage and ESD. I saw on the reference manual in ...
Posted on July 15, 2016 at 12:35 Hello there, I have just updated mxCube to version 4.0. I am genereting startup code for SW4STM I am using arm_math libarry. Since this version, I am getting warning I should not be getting... For example: ...
Posted on August 25, 2016 at 13:33Hi I'm using Nucleo STM32L031K6 for my project and I want to use an external debugger for the board instead of the internal debugger provided on the board. I looked at the data sheet of this STML031 and it says tha...
Posted on August 04, 2016 at 20:09 Hi there. i want to make a pulse counter with stm32f103RB. at first time i using EXTI to count the pulses means configure one of EXTI in falling or rising edge and in the IRQ_hander routine increase a var...
Posted on August 22, 2016 at 16:25Hi,i have a question about Timer1 of the �C mentioned above.I want to use the Timer1 for a SW-Timer with second-resolution.I have the idea, to start the timer with a frequency of 1 KHz and use the Auto-repition-Coun...
Posted on August 24, 2016 at 13:48I have been working on a STM32F051 for a while now. Though despite using reference code from the manual (page 936 in RM0091) for erasing flash, the device does not erase the page. I have traced it into the erase rou...
Posted on August 23, 2016 at 04:36I am using STM32F3 Discovery board to generate six-step PWM signals for BLDC motor drive. The switching was done in SysTick ISR by generating a SW COMG event. When I checked the PWM output on oscilloscope, however, ...
