STM32 MCUs Products

Regarding STM32L4Q5CGT6P I wanted to configure PB8 (I2C1 - SCL) and PB9 (I2C1 -SDA) for I2C Bus, but not able to find GPIO PB8 while configurating .IOC in STM32 Cube IDE I am using STM32 Cube IDE version 1.7.0,

What is the reason for not finding PB8 pin?

How to control a LED strip with the DMX512 decoder and the UCS512C4 IC driver with an STM32?

Hello ST Community.I have to controle a LED strip with DMX drivers LED, but i dont know how to select the chanel and the value.i already have the RS485 module to transmite the USART signal but i dont how and what to send to controle the strip and mak...

Hi, I am using STM32F030ccT6 MC. Using Timer6 & Timer7 in the project. I need to achive 1microsec. so, I need formula for calculate the timer value. I referred user manual & other resources. but that are all not helping me...

Hi, I am looking for a SPI example for STM32H747IDISO discovery kit. I found one on GitHub but it is for Nucleo boards. Thanks, Louis

I'm trying to use HRTIM to generate non-overlaping PWM pulses on 2 outputs, and be able to change which output is first in time. I've tried various methods and find when I change the output order, it corrupts the pulse lengths and they overlap.

Nulceo 64- F334R8. Using Timer A on HRTIM1 to generate non-overlaping PWM pulses on 2 separate outputs. I use 4 CMP registers, defining the start and end time of each pulse (CMP1 = pulse 1 start, CMP2 = pulse 1 end, CMP3 = pulse 2 start, CMP4 = puls...

Can we get information about the type of microcontroller directly from file *.bin ? I would like to know when analyzing the file *.bin what type of microcontroller is it intended for?

An STM tutorial on timers has errors regarding PWM mode, for STM32 MCUs

An STM tutorial on timers has errors regarding PWM mode, for STM32.The tutorial is: "STM32L4 - Timers : Advanced-control, general-purpose, and basic timers"It is a slide-set, with notes. There are at least a couple versions of it, e.g., a version for...

How to write data to flash on an STM32F413ZH

HelloI'm trying to read and write data to the flash on a STM32F413ZH using Keil MDK-ARM. I've been using the following code:uint32_t Flash_Address1 = 0x08140066; uint32_t Flash_Address2 = 0x08140067;   uint8_t Data[4] = {0x66, 0x77, 0x88, 0x99 };   v...

Suspecting the ADC measurements or PWM timer output coming wrong for every 65535 iterations.

Here below is the detail of my application.I am running the PWM timer1 at 5Khz in up-down mode. Two interrupts, one in timer counter equal to zero and ADC fast conversion done.Interrupt generates at every timer counter equal to zero then I start the ...
