Hi, I have an application that should trigger an interrupt on a falling level signal. For argument sake, let's say that I expect it to trigger about once a second. Now, when I run my code, it triggers(the EXTI12 ISR) more like 30 times per second. I ...

Hi, I want to do something extremely basic. Trigger a pulse using software for Timer 1 which is configured in Retriggerable One-Pulse Mode. Background: I can do the above if the Timer 1 is in normal One-Pulse mode. By simply Writing the CEN bit in TI...

Hi, I want to read flash memory to determine whether or not valid data is in the flash. And if this data can be used in my application. in my code, if I deference a Flash memory address I immediately get a ECCD error. Why is this happening? Thanks,

Hi, For my application I need the following, I want to store variables in Flash memory, in order to preserve the data after a Hardware reset. My approach is as follows: 1.) Modify the linker script to keep a page of flash memory outside of the progr...

Hi, I would like to, trigger an update event interrupt using software. My timer runs in One Pulse mode, the idea is, that another event should also run the code in my Timer ISR. So after this other event happens in my code, I don't want to wait for t...

Have you ever done a basic ADC on any MCU ?

Hi Neil,Sure you can if you have the time.If you're already reading the Datasheet/Reference Manual, easier for me to just use the direct register access.

-My implementation relies on the STM32 HAL.The problem with HAL is that you don't know what they do in their predefined functions. To do proper Firmware development you need to check the registers and verify everything is correct as I already previou...

Hi, Have you investigated the following method for your application. In my view it is better to use one Timer(Like Timer 2) as a Trigger input into another Timer.To use Timer 2 in PWM Input Capture mode, can do the period measurement between the puls...
