STM32F030 Errata errata
There's no TRGO2 in STM32F030.There are no Combined slave modes in STM32F030 timers, nor there is any BKIN2.What?JWPS. Please remove the "modern feel and look".

I already have the board
Use the registration code WS-STM32H73-EMEA-MAR25-2021 to buy the STM32H735G-DK discovery board on our e-store and benefit from free shipping. The STM32H735G-DK board is mandatory to participate in this workshop, as it will be used during the hands-o...
Resolved! When timer is enabled it creates initial DMA request even CNT is 0
I want to generate waveform for 8 channel WS2812 leds using STM32F103. This device uses pulse with to transfer bits.. The longer pulse means 1, the shorter means 0.. Because I want to generate 8 channel wavefrm, I configured 3 DMA's, one moves 0xFF t...
Using DMA for USART Rx to get an interrupt whenever a byte of data is received
Hi,I have an application that is running many tasks with different priorities. So whenever the user enters data, the task containing uart_read function might not have executed. So currently I am using RXFNE interrupt which gives me an interrupt on th...
Resolved! Question1: How to know the designated USARTx & UARTx for a particular STM32 line? Question 2: Is there any available document outlining the availability of USART or UARTx peripheral to a particular line?
I did check the reference manual, but it was not stated. I have also seen in an image the same core has different counts of UART. Hence I am a bit confused.
What MCUs would be appropriate for a low power, high UART count, external RAM and ROM application
We need to replace an end of life ARM 9 based SOM and I could use some advice on what ST Micro MCU would be a good replacement. The requirements that seem to be driving the choice are low power, 9 or more UART/USARTs, 2 or more I2C, at least 8 Mbytes...
Where is the CompleteCallbacks are located in layered architecture?
I am using STM32F405xx and Cube IDE environment to evaluate my app. A layered CAN communication is requested. At this point, there are three layer to build this architecture. 1. 1.Layer is HAL library for CAN provided by ST and CubeMx: can.c and can....
Why is STM32F303RET6 not available ?
We created a design with a STM303RET6 (lqfp64) microcontroller. For the first prototype pcb's we need 5 of this type microcontroller. But the problem is that no one can deliver this item (e.g. Farnell, Mouser etc). They don't give any explanation why...
TIM1 appears to be incrementing at a strange rate when generating a pulse
I am working with the STM32F769 microcontroller and I want to generate a pulse on PE14 that is "a few" milliseconds wide. My SystemCoreClock is 216 MHz and my timer, TIM1, is hooked up to the APB2-bus, which is clocked at 108 MHz. My code looks like ...
