Posted on June 19, 2013 at 08:02I have an STM32F4 project that uses DMA for UART transmission, and it's working well. I now need to add the ability to interrupt the DMA process and send a single byte immediately (or, more specifically, once the byte...
Posted on June 19, 2013 at 13:20hey all when i include the header stm32f4_discovery.h it recognizes it well , but it dont recognize ''GPIO_InitTypeDef'' !! and ''RCC_AHB1PeriphClockCmd'' and all GPIO_Pins! and to be sure of the header i attached ...
Posted on June 19, 2013 at 16:25Hello to everyone!What does it mean the ''FM+ capable'' feature of a pin? There is 5V tolerant, and 5 V tolerant I/O, FM+, pin (STM32F051x4 datasheet - pin PB6, PB7, PB8, PB9) and what is the diference? This feature i...
Posted on June 05, 2013 at 22:36 told me to report on this forum any corrections needed in reference docs and code. These corrections apply to the latest published reference manuals for STM32F3xx: RM0316: STM32F302xx, STM32F303xx and STM32F313xx...
Posted on June 17, 2013 at 14:52I need to update this function to stm32f4xx.h.void delay_us(u32 Nus){ SysTick_SetReload(delay_fac_us * Nus); SysTick_CounterCmd(SysTick_Counter_Clear); // error: 'SysTick_Counter_Clear' undeclared (first use in...
Posted on June 17, 2013 at 08:50 Hello, I want to put the data from buffer(RAM) to the GPIO port(transmit) and from another GPIO port to the buffer(RAM)(receive) with the 2MHz clock. So I'm using DMA with input capture mode of the timer. ...
Posted on June 18, 2013 at 11:25I write this code witch turn on the 4 leds of the stm32 when pushing the bouttan and after it wait for some time and turn off the 4 leds. I checked the code without the delay it work fine but whith the delay the progr...
Posted on June 17, 2013 at 18:30I build my own STM32F405RG Stamp and try now to get the USB FS running. For to make good progress I use the libraries, which are available for the stm32F407 Discovery. I use Atollic True Studio Lite and ST-Link/V2 SWD...
Posted on June 17, 2013 at 10:37Hello,I use the STM32F407 and I have to link 3 different slave devices on the same SPI bus (an accelerometer, a touchpad controller and a screen). I have no other solutions. Each device is activated with chip select p...
