Posted on March 31, 2014 at 01:11Dear, as in several examples, i implemented my _sbrk function to be able to use malloc, as (copied from examples): extern int _end; /* * _sbrk needed for malloc */ caddr_t _sbrk ( int incr ) { static unsi...
Posted on March 02, 2014 at 15:43Afternoon all, I am having some problems with clock rate setting on the stm32f103 and I am hoping you can point me in the correct direction. (I think this is a very simple problem!). First up I do not have a scope on...
Posted on March 30, 2014 at 18:34Hello, at first, I try to explain my target functinality: -TIM1 generates a 3PH Center aligned PWM - the ADCs are configured in triple mode, some channels are converted and the DMA generates an Interrupt when the Tra...
Posted on March 31, 2014 at 12:49Dear All, I've recently upgraded the CPU on a product using a 407 device, to a 427 device. We are using the DMA2, in memory to memory mode, to write from external SRAM to a display controller also on the external bus...
Posted on March 31, 2014 at 12:53hi,i use the stm32f407 with atolic TrueSyudio.on the evaluation board ( stm3240G-Eval) things were OK.when i start working on our new board, different code lines (which i dont understand the common ) cause the debug...
Posted on March 26, 2014 at 11:36Guys, Does R/B pin on Nand flash needed on the software ? I can't find R/B pin on GPIO definition, Anyone knows ? thanks #nand
Posted on September 19, 2013 at 17:37Hello everybody,Is it possible to link same pin number of different GPIO ports on the same EXTI line ? For example, create an interrupt on line_0 for the GPIO pin A0 and the pin B0. It seems impossible to achieve...
Posted on March 31, 2014 at 02:51I am experimenting with the STM32F429 and wish to use the LCD-TFT controller (LTDC).I am interested in generating monochrome 640x480 VGA video and hence only need 1-bit output rather than 8-bit RGB. Does anyone know ...
Posted on March 31, 2014 at 02:29Hello, I am trying to activate the interrupts on PC4-7 so that a flag will appear whenever these pins are set high. I have the base structure of the code completed, however whenever I try to place a break point to se...
Posted on February 17, 2014 at 16:07 Hi, I'm using the F407 (Discovery) as a SPI-Slave with DMA enabled and a ''data ready'' signaling line. I'm currently trying to transfer data in dual buffer mode (the host cpu might also send configura...
