Posted on April 25, 2015 at 03:55What is the page size for flash on the STM32F405 chip? I can find the layout of the flash in RM0090 manual, but the page size is nowhere to be found. Is there somewhere else I should be looking? Surely it's docume...
Posted on April 25, 2015 at 04:52This error lasts a long long time, and maybe still exists other version of stdperiph or Cube. In STM32Cube_FW_F4_V1.5.0 the error is in this line of stm32f4xx_hal_uart.h: #define UART_BRR_SAMPLING8(_PCLK_, _BAUD_) ...
Posted on April 19, 2015 at 23:45Hello, I'm using IAR and I configured stm32f429 discovery board by STCubeMX and its libraies. It seems to work fine when I run my code with Download and Debug mode. But when I exit debug mode the board stop running ...
Posted on April 24, 2015 at 19:12Hi!I have STM32F407VET6 MCU with 192kB RAM. I need allocate 150kB for storing image after processing data. However I can't allocate such big array. I though I should increase heap size, but I can't increase it more t...
Posted on April 22, 2015 at 19:02I have a board using an STM32F105. There is a GPS connected to UART4. I've been trying to get the RXNE interrupt working for a couple of days now, but I must be missing something. The UART seems to be enabled, as I...
Posted on June 26, 2012 at 16:26Hi,My microcontroller is a STM32F103CB.I followed the AN2557 to do an IAP in my software. Everything works fine but now I would like to do something like a dual bank features.I can flash two firmwares at two different...
Posted on April 24, 2015 at 07:13Hi, I would like to ask how to sample adc values (potentiometer) using DMA interrupt? #adc #dma #stm32f3discovery
Posted on April 24, 2015 at 17:35Hi,I am doing development on an STM32F429 using CMSIS-RTOS/RTX. I am getting the following linker error:.\output\LmMain.axf: Error: L6200E: Symbol SysTick_Handler multiply defined (by hal_cm3.o and stm32f4xx_it.o).H...
Posted on April 24, 2015 at 15:14The problem is simple. I uploaded a buggy program using ST-Link to a stm32f303 prototype board. The bug was that the routine that kicks the watchdog in the power supervisor does not work. Therefore it keeps resetting...
Posted on April 23, 2015 at 14:55All I get is an error page that says:''An unexpected error has occurred./public/STe2ecommunities/mcu/_layouts/spcontnt.aspx?&url=/public/STe2ecommunities/mcu/Lists/cortex_mx_stm32/Flat.aspx?RootFolder%3d%252fpublic%2...
