Posted on December 03, 2014 at 12:15I have ADC1 and ADC2 sampling by using the hardware signal (external interrupt) from a timer. They use the same timer, but two different channels.It works for 10 minutes+, but then the ADC ISR is no longer called....
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...
