Posted on August 23, 2014 at 09:52 Hi, I am using a custom board withSTM32F401RB MCU and I want to run it at 84MHz from PLL<-HSE configuration. I have an 8MHz crystal on the board. But I don't know how to do it. I ran the STM32CubeMX (I don't...
Posted on August 22, 2014 at 06:05Hello, I load several example projects unmodified into Keil and compile as soon as I enter. When the project enters the linking phase, I get an error that HAL_DMA_Init is an undefined symbol, and the project won't c...
Posted on July 06, 2014 at 15:59 hi guys, i create a program to generate pwm signals in stm32f407 i did it in past for another timer but when i wanna do it for timer1 i doesn.t work. here is my code : #include <stm32f4xx.h> voi...
Posted on August 21, 2014 at 20:08Hi, I am trying to use CANbus on STM32F303VC6. I get it working in loopback mode. But the message is not getting sent in Normal mode. I have turned on SB21 and SB22 to connect the ports PA11 and PA12 to P2. When I d...
Posted on August 16, 2014 at 06:06HiI have problem in sharing the PA5 functionality on STM32f407IGT6.As I need to use both of DACs in my design, and HS_ULPI_CK is also routed only on that pin (there is no multiplex to any other pins).I can not use O...
Posted on August 21, 2014 at 16:14 I am trying to use theSTM32F429 Discovery boardin order to communicate in a transmit only mode to an LCD over SPI. However, every time I write to the data register to output, I see nothing get loaded in my debug...
Posted on September 04, 2013 at 18:42Hi, I would like to know if TIM16 and TIM17 can be used in external clock source mode 1. There is any reference in the Reference Manual that it doesn't. So I suppose it is possible. I develop my board and now I w...
Posted on August 21, 2014 at 14:46Hi everyone, I've been working on the STM32F4 and I would like to count pulses from some odometer. There are two types of odometer, the ones that output two signal in quadrature and the other that output pulse on ...
Posted on August 21, 2014 at 10:02Hi,i am facing problem for the PiD controller.what parameter i have to use it for the positive & negative nos for calculation purpose.Kindly look following code New_Duty_cycle_buck=(Previous_Duty_cycle_buck + Error_...
Posted on August 21, 2014 at 02:53As far as I knew, SYSTICK Timer is a 24-bit down counter. For now, I need to know the precise consumption time for the memcpy function. Suppose I set SysTick->RELOAD = 511, it will turn out two cases as the followin...
