Posted on January 26, 2017 at 18:21When using CubeMX V4.18 with the Nucleo-144 board with STM32F767ZI processor to configure the Ethernet RMII, I discovered that using the MII pins as GPIO cause pin configuration warnings. For example, pin PB0 is no...
Posted on January 26, 2017 at 15:18HiI just buy a JLLINK TRACE and I want to add the trace function in my programI use GNU ARM GCC and eclipse.Do you know how to activate the trace ETM 4 bits ? I found these articles :https://mcuoneclipse.com/2016/1...
Posted on January 26, 2017 at 16:32Hi,I have two freshly created projects with the STM32F407 in 100 Pin LQFP housing. I admit I didn't read the datasheet properly and found out afterwards that not all timers are 32 bit timers (which I would expect i...
Posted on January 26, 2017 at 16:18 Hi everyone, I'm new in STM32 and try to run I2C but when I try to connect with other device program stay in endles loop while (I2C_CheckEvent(I2C2, I2C_EVENT_MASTER_MODE_SELECT) != SUCCESS); What coul...
Posted on November 18, 2016 at 13:17Is it possible to wake an stm32l4 from shutdown or standby modes using the swd interface and swd protocol ? I know it is possible to set control bits that enable debug during shutdown/standby, but I'm asking so...

Posted on January 24, 2017 at 11:58Hi,I'm running in some communication problems with USB at the STM32L052 on Linux. If the device is connected via /dev/ttyACM0 and transmitting data to the host, I see an echo on the receive buffer inside the STM. I...
Posted on January 26, 2017 at 01:55I have 'Getting started with STM32F4xxxx MCU hardware development' pdf. It is from December 2016, probably the newest. In page 30/40 Table 8 there are 5 pins needed for programming? Five pins. But on the next page ...
Posted on January 26, 2017 at 12:04Hi,can you read the UID of the mentioned processor bny means of the bootloader? Reading AN2606, Table 106 it seems that the UID is out of reeadable range. Maybe somebody could confirm?Regards
Posted on January 26, 2017 at 08:35Hi all,I try to read ADC values from the STM32f303 without success. With one channel everything is working fine but when I want to read the next channel it is not working any more. maybe I am doing something wrong ...
