Hey!I have been with a problem with the stm32l452 comparator for a few days now and I can't figure it out. The interrupt of COMP1 triggers on both edges rather than rising edge.I tried differents configurations but main is the following:hcomp1.Init.I...
Hello, I made a an esc using an arduino a year ago and I wanted to try it with my stm32L476RG, for some reason my code doesn't seem to work, and I think that I'm doing the switching of the comparator input minus wrong, can you tell me if this is the ...
Hello I have a Nucleo board L476RG and I would like to change the trigger mode of the comparator on the fly, the problem is that I cannot find the register responsible of this in the datasheet.I guess it's not related to the comparator but to the EXT...
Hi,I am using STM32L476. COMP1 and COMP2 are configured in window mode, and that is working great. I am also using TIM1 break function. Below is a summary of the problem that I am encountering:If I use COMP1, and only COMP1, as a source for BREAK or...
Hi， I'm using comp1 of stm32g474rbt6 and setting 70mV hysteresis.when a DC signal input PB1,the output always shake。But comp4 do not like this.
I want to generate differential signal from this MCU itself. I'm using NUCLEO-H723ZG doing this which has DAC, COMP and TIM built-in.I've used 2 DAC for generate 2 simultaneous UART signals (If there's other ways to do this please recommend) but it's...
I tested with NUCLEO-F303ZE (72Mhz clock).I checked the time when comparator makes interrupt as below ------------------------------------------------------------------------------------void COMP7_IRQHandler(void){ DRV_GPIO_Port->BSRR = (uint32_t)DRV...
My STM32F0 won't show up under "Ports " in my device manager. It does, however, show up under "Universal Serial Bus Devices". I'm trying to print to a serial monitor. I've spent over 12 hours (low guess) trying to troubleshoot this issue. Here is wh...
I have NUCLEO-144 H723ZG board. I created a frequency meter app for the NUCLEO board, but the quality of the frequency measurement a sinusoidal voltage is very poor. I have a generated 720mV RMS, 126.7Hz signal between 0 and +2.5V (max) biased to +1....
Hi, I going to use on-chip comparator of STM32-Nucleo board G474RE in my application, the sensed voltage could go negative, the general operating conditions table (page 84) in the datasheet (Datasheet - STM32G474xB STM32G474xC STM32G474xE - Arm® Co...
