Posted on February 11, 2012 at 01:17hello One question: when i am using: char table[10]; (...) *(unsigned int*)&table[1]=0x12345678; should the pointer be dword alligned in RAMy ? Can I make safely such access? Or it is forbidden in ARM architecture...
Posted on February 10, 2012 at 11:54Hi, Using STM32F205RCT6. We used ADC1/DMA with Timer 1 as trigger and worked fine. The temperature sensor is only connected to ADC1 so I have to move ADC1 -> ADC2. Now we have problems with the trigger - it doesn'...
Posted on February 09, 2012 at 17:11Hello I am using STM32RBT6 with my board and all is good except serial with 115200 baud rate, 57600 and lower is working correctly. I just see weird characters when receiving data. I can't get it work either with ...
Posted on February 08, 2012 at 16:02Hi, How can i use PC14/15 as GPIOs? I turened off LSE by using this function and configure PC14/15 as input floating: RCC_LSEConfig(RCC_LSE_OFF); But the ports does not read any data, What do i miss?
Posted on January 18, 2012 at 17:17 Here is a description of the PDM audio software decoding library from the AN3998 PDF: The PDM audio software decoding library includes one header file pdm_filter.h and binary/object codes for the following ...
Posted on February 09, 2012 at 11:51 Hello, I would like to use a timer on Reset mode, but I have some problem : My goal is to never call the timerinterrupt until the trigger input is switching. I want to enter in the timer inte...
Posted on February 08, 2012 at 03:43Hi, Currently, I am designing an application board for STM32VLdiscovery with batteries. In order to decide the parameters of step-up converter, I would like to know the current consumption of STM32VLDiscovery, alt...
Posted on February 08, 2012 at 20:30I am new to arm and designing a new prototype board with a STM32F417 and 2 NAND Flash chips. In the data sheet it says the HCLK can go to 168MHz BUT it also says that the FSMC maximum clock is 60MHz at 3.3V. Does...
Posted on February 08, 2012 at 20:49I have an application that needs 9 (yes, 9) serial ports. The STM32F103 I am using supports 5, so I am adding an external 16554 quad uart. As part of my testing before actually getting a board built, I am trying...
Posted on February 06, 2012 at 18:02I am trying to interface with an SPI port device which requires a 24bit transfer, I have successfully managed to achieve this using the example code and standard peripheral library but I am seeing gaps between byt...
