Posted on November 20, 2015 at 17:40Hey guys, I just need a confirmation, that I understood this correctly. To compute the orginal signals amplitude from the FFT amplitude, you have to divide the FFT specific frequency amplitude from the FFT length ...
Posted on November 20, 2015 at 17:37Hi All,I have recently moved over to using a Segger J-Link JTAG adapter. I'm using JLinkGDBServer, ARM Tools GDB in eclipse. The device on my target hardware is an STM32F427II. It appears that I only have R/W acce...
Posted on October 18, 2013 at 11:04Hi all,at page 135 of http://www.st.com/st-web-ui/static/active/en/resource/technical/document/reference_manual/CD00240193.pdf, I found a note: ''To know which functions are multiplexed on each GPIO pin, refer to t...
Posted on November 19, 2015 at 14:13Hi, I have problems in my project when I set the core frequancy above 100MHz. Up to 100 MHz I have no problem. When frequency is higer than 100 MHz CPU goes in hard fault. Using a frequncy of 120 MHz CPU goes in h...
Posted on October 20, 2015 at 14:44Hi,I use the UART4 of stm32f103ZGH6 on my application board as a RS 232 port. When I load the main app program with Keil uVision4 into the target flash starting at 0x08000000, the RX/TX of UART4 work fine. However,...

Posted on November 12, 2015 at 10:26This is a rather complex problem. I have an interrupt routine running under the systick handler with a period of 10mS. Within this I do 4096 reads of ADC3 via DMA2_Channel5, which works fine. Single shot modeThe p...
Posted on November 18, 2015 at 11:37Hello all, I'm currently working on an STM32F411VEH6 MCU and I'm trying to launch an application located at the flash address 0x08004000 with a bootloader at the flash base address (0x08000000). I've read a bunch ...
Posted on November 19, 2015 at 19:03 Hi, I wanted to know how could I have 5V in a pin associated with a timer. I do this configuration: /*GPIOA Configuration: TIM9 CH1 (PA2)*/ GPIO_InitStructure.GPIO_Pin = GPIO_Pin_2; GPIO_InitStruc...
Posted on November 20, 2015 at 11:00Hello,I am activating hardware watchdog (by using option byte). But sometimes, i need to deactivate this hardware watchdog, so I wrote some J-Link scripts to disable it before flashing or erasing my MCU. Unfortuna...
