Posted on March 30, 2014 at 19:33 Dear community, Knowing that the RTC manual stated that the LSI is not suitable for the RTC, I am trying to use the HSE clock source for the RTC. I initialized the clock and RTC but the i was unable to read the time...
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...
Posted on March 29, 2014 at 02:21 Hi, I'm entering in STOP mode with the command: PWR_EnterSTOPMode(PWR_Regulator_LowPower, PWR_STOPEntry_WFI); But, when it resume from STOP, I cannot write to EEPROM anymore. I'm unlock...
Posted on October 29, 2013 at 15:56Hello everybody, I'm looking for a working example using OUT Endpoint on STM32F4 Discovery board. I have no success with it. I modified Demo sample for an OUT Endpoint and Custom usage, and try to send one byte rep...
