Posted on December 03, 2014 at 05:10Hi ST,I connect my module usart tx/rx with STM32F072x PA10/PA9, and initial PA10&PA9 as usart1 to communicate with my module.Besides, I use printf to IAR Terminal IO window to debug, not redirect printf to usart1 ...
Posted on December 02, 2014 at 19:30Hello ST gurus! May I inquire on the right sequence of steps to unlock a device (level 1 lock) to unlocked (level 0)? The STM library reveals the following sequence is required to lock: FLASH_OB_Unlock(); ...
Posted on December 03, 2014 at 09:47Hi,we have to manage a CFP Module via MDIO with STM32F429. Unfortunately the module requires MDIO according to 802.3 clause 45. I am right that the 429er supports only the older version (clause 22)?Is there anothe...
Posted on November 26, 2014 at 02:47I am using VCP firmware from STM, but I have a problem when I am transmitting my data using the CDC classI am sending data from my firmware to my PC, if I did open the serial port in my PC side, and i am still sen...
Posted on December 03, 2014 at 05:33I am using an �030 with its internal oscillator. Thus I should be able to use F0 and F1 for anything any GPIO pin can be used for. I turned on internal pullups on these pins and only F1 worked. F0 read high or ...
Posted on December 02, 2014 at 22:56Hi All,I try to amplify audio obtained in mic(mp45dt02) with amp(CS43L22 ) and hear the voice on headphones. The way to do this is not with STM32F4, but directly via PDM_OUT port. This is possible as mic output is...
Posted on December 02, 2014 at 08:29Hello ! I am struggling to set the initial state from which the toggle mode of output compare (STM32F405, TIM1) starts. I tried to set OCM1 mode to '101 : force active level', '100 : force inactive level' respecti...
Posted on December 02, 2014 at 22:15 Hi, I am playing with stm32f4 discovery board's external interrupts. Consider 2 external interrupts:one is higher priority than the other.What i am trying to do is to decrment the priority of the higher...
Posted on December 02, 2014 at 21:24Hello,I designed my own application starting from VirtualComport_loopback example project.I have a modbus client protocol running on USB and using CDC_Send_DATA() and CDC_Receive_DATA() send and get data from PC v...
Posted on November 07, 2014 at 17:52I am working with a STM32F051xx for a real time clock application. Looking at the datasheet (page 53, table28: typical and maximum current consumption from the Vbat supply), it is noted below the table that the MC...
