Hello,In my project I need to sample 3 phase current to see if where is short or not. I am using STM32H753 HRTIM. Not only that I must place sampling point as close to PWM transition from high to low as possible (peak current)I connected phase curren...
Hello,In my project I need to have ~25KHz high resolution PWM generation. So for this I selected STM32H753 with 480MHz HRTIM1.I am struggling producing correct outputs for my needs, maybe some one has this done already and care to share the project ?...
Hello,I need to detect input when it goes over REF/2 (1.65V). I do supply VREF+ pin with 3.3000V.My signal has offset of 1.2V, and it will go over 2V when I apply signal to it.Everything is working, but it has unexpected behavior. I can only use nega...
Hello,In my application i need to run double for loop for data inside SRAM. and I would love to speed up my program as much as possible.uint32_t xs = 0, yx = 0, sum =0, i = 0;for(uint32_t x = 0 ; x<600 ; x++){ for(uint32_t y = 0 ; y<600 ; y++) ...
Hello,In one of my boards I was planing to use CANBUS bootloader and STLink V3 with external canbus PHY to program MCU.I was unable to program it, I can see STlink V3 does try to do some TX on CANBUS pin, but where is no packet available that could b...
Created a ticket for STM32 engineers and they finally provided clarity on this matter. As it turns out, it uses completely different REF, and it is independent of VREFBUF and external reference. It is an integrated 1.2V reference that could not be ch...
Tested on NUCLEO-H723 board and used example for CUBE folder. Connected power supply with multimeter on top of PB0 pin.And now I was able to test threshold, and is exactly at 1.2V (with COMP_INPUT_MINUS_VREFINT setting). This is why half of my boards...
I am using external reference. DAC is working as it should. I can't use anything else than 3.3V . If I switch to other voltage, I would need to change my hardware, like op amp gain settings, ADC input divider values and so on.My goal was to get best ...
