Hi all,im trying to bring a timer interrupt to work. In the first step I want to create an LED blinky.For that I followed the instructions from the Knowledge base example (How to generate a one second interrupt using an STM32 Timer). The only differe...
hello i am working with i2c i used register for coding i2c but when i configure AFRH register i cant upload my code to my board i have target not responding error then i tried hal library but nothing changed
Hi, I am trying to detect whether a reset event was caused by power on rather than any other reset such as a button reset or a software reset. I attempted to use if (__HAL_RCC_GET_FLAG(RCC_FLAG_PORRST) != RESET)but the compiler reports that PORRST ...
The RM0440 ch. 28.3.18 rev7 mentions on page 1128:> An interrupt is generated if the BIE bit in the TIMx_DIER register is set. A DMA request can be sent if the BDE bit in the TIMx_DIER register is set.Unfortunately, the DIER register does not contain...
Hello. I've noticed that DCMI/PSSI code does not provide this functionality, but it is very handy when using DMA in circular mode (ADC, frame buffer pumping to other interfaces, etc.). I've tested DCMI+DMA circular mode on F4 and PSSI+DMA circular mo...
Some ARM/STM32H7 CPUs have a problem with single stepping through code. Which CPUs didn't have this problem? I have planned to use STM32H750 because it is now somewhat available, but I could swap.
I have tested all 3v connections going into the st-link chip, but the bi-color led is not blinking when it is connected via USB. Please help.
Good morning.....I have a CubeIDE prj with .ioc and main. All compiles fine. I have created a second file with a main function (gfsk.c). I have excluded the original main.c for build. I would like to know when I go back into the .ioc to make a sm...
Hi, I'm trying to do embedded 103c8t6, and I'm having some trouble with selecting the right crystal.Here is my Schematic. I'm using ABS07-32.768khz with 12.5pF load Capacitances and the equivalent series resistance is 70kR. I took Cstray as 5pF that'...
