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'...
After running into some issues during an OS migration, I ran a firmware update on a nucelo_h743zi board using the stLink utility. After this I ran into many issues with flashing and debugging. While I can flash the board with openocd v11, it has some...
According to RM: "In the NOERASE configuration (TAMPxNOER=1 in the TAMP_CR2 register, ITAMPxNOER=1 in the TAMP_CR3 register), the backup registers and other device secrets are not erased when the corresponding tamper event is detected. In addition, t...
I'm attempting to optimize the amount of instructions/time it takes to move data from CPU to GPIO. When doing ODR = X, I lose about 40ns, closer to 80 because I need to use 2 ODR writes to different ports and in general ODR output seems to sit at abo...
