Stop mode with Interrup EXTI
Posted on April 28, 2017 at 10:17Hello family ST,I would like to use stop mode with an interrupt Pin,I tried the PWR Stop example in STM32Cube_FW_L0,When I put the PA12 Pin to Vcc I have ?c wake up after it runs the program and so it resumes stop mo...
udp packet sender
Posted on May 01, 2017 at 15:08I've implemented on my board the UDP packet server as a task for a board which has to support ethernet, but nothing is defined for the interface. So far so good. I send UDP packets to it and it receives and echoes th...
My MCU works fine in debug mode but out of debug mode it suddenly fails
Posted on March 25, 2017 at 21:09Hi,Something is driving me crazy.Actually I have written a program thatit:receive 100chars each 60ms from USART1 and 2 with RXNE interrupt(baudrate 57600)receive100chars each 100ms from Ethernet with PHY and after pr...

UART problem betwen stm32f407 and fpga
Posted on April 30, 2017 at 10:03Hello,i have a design where a fpga sends a packet of 10bytes at a baud of 57970 to USART2 of the stm32f407VE device.The idea was to use USART2 where RX pin is receiving data from the fpga, and the TX pin sends the ...
