Posted on August 18, 2014 at 12:37Hi all,After some battle i was able to set a jump from my custom Bootloader to the App using in Keil V5.Custom Bootloader resides in IROM 0x08000000App resides in IROM 0x08020000Need to set both mem addr in the Ke...
Posted on June 01, 2012 at 16:59 I am trying to erase and program a 16KB sector (sector 2) in the STM32F405 (rev A)on the ST3240G eval board. The problem is that two error flags (PGSERR and PGPERR)are set and cannot be cleared. Soon afte...
Posted on April 26, 2014 at 23:58Hi all, When my program is in an interrupt caused by an external rising edge, the systick interrupt no longer occurs. My first thought was that the priority of the systick was lower than that of my function, so I us...
Posted on September 23, 2014 at 13:59Hello, with regard to ADC noise on the F407, AN4547 (F407 -> F42x migration) tells: '' Resolved with new behavior to enhance the accuracy'' However I don't see any description of the new behavior! Can anybody cla...
Posted on September 22, 2014 at 11:45I want to interface LCD 800 x 600 x RGB 24 bit Display. for that i used SDRAM, NAND Flash, and other needed like touch Controller, SDCard, USB 2.0 etc. While designing in Cube i found that NAND and SDRAM shares t...
Posted on September 20, 2014 at 11:50With my STM32F4 discovery board I cannot get the UART4_IRQHandler to be triggered on incoming serial data. However the USART2_IRQHandler functions as expected and when the data is ready from the UART4 RX data reg...
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 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 17, 2014 at 01:17Hi allI need to use Timer 6 on the STM32F407VG. Its interrupt is sharedby one of the DAC overrun interrupts. Is there something extra I have to do compared to another timer with its own global interrupt in order ...
Posted on September 16, 2014 at 08:04Hi, I am a beginner in STM32F4 Discovery. I am using STM32F4 Discovery MB997C board. The firmware STM32F4-Discovery_FW_V1.1.0 contains example for LIS320DL. But my board has LIS3DSH mems accelerometer. Is there a...
