About SWD signals
Posted on June 14, 2018 at 16:00Hello, please tell me, what is the minimum number of signals required for the SWD interface: SWDIO, SWCLK? NRST is also required or possible without it?

Posted on June 15, 2018 at 17:43Hey guys, I am using a STPM34 Evaluation board with a STEVAL-IPE023V1 USB interface to measure a current from a simple circuit through SPI interface. for some reason I always read 0 for the current for C1 and 4.6189 ...

Posted on September 13, 2017 at 23:53I am using https://community.st.com/0D50X00009XkdsSSAR method to drive a servo-like motor interface. In the system, if E-Stop is pressed, I'lI have stop the motor immediately. Is there a way to find out the numbe...
Posted on June 14, 2018 at 22:58Hello!I used STMStudio on the NUCLEO-F303RE for plotting signals and it worked fine. Now I built my own PCB with an STM32F303RC, broke off the debug-part of the NUCLEO board and startet debugging with the SWD connecto...
Posted on June 15, 2018 at 13:28Hi !We are working with X-nucleo-IDB05A1, we had some disconnection issue without reason. and we figure out that there is HCI_DISCONNECTION_EVT generated each time. The reason is connection timout ,which can be genera...
Posted on June 15, 2018 at 13:26I'm using stm32l100C6-A to communicate with gas gauge by I2C. My code tries to start I2C transfer, like this:I2C_GenerateSTART( i2c_periph, ENABLE );and sometimes it works, transfer is completed, all is well. But some...
Posted on August 10, 2016 at 09:39I am used to chips being marked for example ''STM32F405VGT6''. However, from several people I hear that now chips marked with an additional ''U'' at the end are showing up. Date code 1613 or something like that. One...
Posted on June 14, 2018 at 08:37Hello,Could you describe difference in use FIFO0 and FIFO1 for CAN1 and CAN2 in stm32f4 mcu? For example if I configure CAN2 for receive in FIFO0 and configurate filters 14 all work success, but if I try use FIFO1 wit...
