Hello, everyone. I am developing a prototype using a STM32L475 and the NOR flash memory MT25QL512ABB. I am using the QuadSPI peripheral for the communication with these parameters:I used the QSPI_ReadWrite_IT example as a reference to fill these para...
I am designing a product with an STM32G474CET (LQFP48 package) and would like to use the ROM bootloader with I2C; looking at AN2606 section 48.1, I see that I must use I2C2, I2C3 or I2C4 if I want to use the ROM bootloader.This is fine, but according...
i'm trying to run a simple blinking led program on my stm32f103c8t6 (after i run it several times before successfully), and it doesn't work, when i fix the delay in 1000 ms the led is always on, when i decrement it to 100, 200, 300 it's working prope...
I'm going to rip my hair out... I mean There has been an issue with rapid disconnect and reconnect of the USB on our product, where the USB stops communicating. We enabled early suspend and when an erratic error (EERR) bit occurs during an early susp...
Hi guys,can someone please explain the internal trigger connections for the stm32f410 controllers to me?According to the referance manual (RM0401, see below) only TIM1 and TIM5 can be configured as slave timers with just ONE possible internal trigger...
Hi,I want to power a STM32Ux based board using USB-C port. I am required to use two numbers of a Type-A to USB-C type of cable and also it should support USB-C to USB-C type of cable in OR ring. Max load current of the board is less 1.5A. I am looki...
Missing info about PG12,PG13, PG14, PG15 alternate functions in Table 22 (datasheet DS14359 Rev 2). I hope that PG15 AF9 is PSSI_D13 like PG11.
Hello, I am looking for very old STM32CubeIDE project example for IR TV remote control to see how TIM16 and TIM17 are set up and controlled.I am not interested in manuals and instructions: better one time to see then read about it 100 time and not ge...
Hi I am working on an STM32L433 using STM32IDE. When running in debug mode, the USB CDC is recognized when plugging in the cable (into Windows 10 and 11) . But when I compile as release mode the USB isn't recognized . I am using the HAL for USB . An...
Hi, i'm implementing a PWM signal using STM32, the problem i'm facing is that when i set the duty cycle of the pulse to zero... i get the pin to stay high, even if i disable the timer associated with the PWM output.This are my setting:My APB2 Bus is ...
