Posted on September 19, 2014 at 06:42Hi, Can anyone please tell me why there are 4 different Access modes i.e A,B,C and D to access SRAM or NOR flash?. Furthermore can anyone tell me how to add more wait states to access memory mapped peripheral wit...
Posted on September 19, 2014 at 03:46Hi,I working with STM32F103 chip and trying to test SPI2. I use the example from: STM32F10x_StdPeriph_Lib_V3.5.0\Project\STM32F10x_StdPeriph_Examples\SPI\SPI_FLASHBut replace#define sFLASH_SPI ...
Posted on September 10, 2014 at 08:54Hi All,I have a quadrature encoder interfaced to my STM32F427 using TIM2.In encoder mode, TIM2 counts up in one direction of the motor but does not count up/down in the other direction.I am adding my init code be...
Posted on September 16, 2014 at 17:38Hi everybody,I'm working about the creation of an automotive dashboard and I'm going to use a STM32 microcontroller, in particular a STM32F103.I'd like to have some suggestions about the LCD display choice, here ...
Posted on January 30, 2014 at 14:47I've been running the demonstration code and it's been failing in the MEMS selftest.The function call below puts 0x3F into temp whereas the value in the datasheet and in the function states it should be 0x3B. The v...
Posted on September 16, 2014 at 13:54I am trying to use multiple interupts on my nucleo board. I have used the cube hal. My problem is that I dont get the interrupts generated on the PB0 pin, but the PB1 works ok. I have tried to do the intializati...
Posted on July 31, 2014 at 03:55 Hi there, I am using the STM32CubeMx code generator with the STM32L053 discovery board. In CubeMx, I enabled USART2 and changed the baud rate to 9600. Also, I configured the pins PA0 for user push button, PA5 for...
Posted on September 18, 2014 at 02:05I want to change polling SPI to DMA SPI. Now I get stuck and have looked up lots of material. None of them is working for me. The original polling SPI code works fine. I implemented the following code for the DMA...
Posted on September 18, 2014 at 13:24Hello community,first of all I’m using the STM32F103RCT6, CooCox IDE 1.7.7 and ARM GCC 4.8. Now to my problem. I’m trying to implement a task similar processing by using the Systick timer. I initialized the SysTi...
Posted on August 01, 2013 at 10:33Hi,I need to store a byte array in the STM32F205 flash memory. I've followed an approach that was working on a STM32F103 mcu, but now it doesn't work anymore.The problem is that the first call to the FLASH_ProgramBy...
