Hi,I want to give to a F103 the faculty to program any other F103 in one touch on the blue button... with a known .hex program.only the SWD link between them.User Scenario:The user plug a new F103 (SWDCLK+SWDIO+GND+3V3) to the 'loader' (without any P...

Posted on March 28, 2017 at 12:26Hi,I am using a https://community.st.com/tags♯/?tags=stm32l1 on the STM32L152c-discovery and trying to reach a lower power consumption.But I can't reach less than 0.6mA !!! (10x more than in theory).Where this curren...

Posted on February 23, 2017 at 11:48Hi,In the current datasheet of STM32F103 (DocID13587 Rev 17) it is written:5.3.14 NRST pin characteristics The NRST pin input driver uses CMOS technology. It is connected to a permanent pull-up resistor, RPU (see ...

Posted on January 24, 2017 at 07:58Hi,We configure the timer 1 to run a PWM signal on PA8 & PA9.It works well with the debugger, but when we power the MCU directly, the PWM is not running ! (We can confirm that the main is running... with a manual G...

I found my mistakes...If you read this post beacause you met similar issue, your problem is certainly different...but I suggest you to check your "ranks" in the config of channels.With G4, the ranks are not as simple as on STM32F1 family.... ! (0->6-...

Hi,Sorry to re-up this old subject... But it seems to match an issue I have... and it can be better than reopen a new one. In our case, with G431KB (+cubeide last version 1.15):- TIM6 triggers ADC2 (Both interrupts TIM6+ADC2 confirm that ADC do the j...

I have the same issue.... I think it is related with some recent changes in st-link firmware.Indeed, I use the Nucleo F103 with VCP in many contexts since years (and "student-proof" contexts!... which is.... instructive ^^).Recently, the VCP is somet...

Posted on June 06, 2017 at 14:48I had the same problem (on STM32L152)... and I found this subject last week...I tried to invert the call to have RTC_GetDate() AFTER RTC_GetTime()... and I got good results. As a feeling, I guess it solved the problem...

Posted on March 28, 2017 at 17:48Thanks,I compared and used this code, and get no difference in the current.I found 300uA in the useless boot0 pull-up. So it remains only about 400uA.I am not sure the MCU is eating this current, but there is nothing...
