In my STM32CubeIDE project, the source code and project file directories are different. The source files are available as linked folder. Therefore, I had made a manual configuration for the source file paths and include file paths. Some paths are rel...

I am using STM32F070 controller. Currently, I am in need of improving performance of the software. I tried to do some measures such as optimization of my code itself and raising the optimization level of compiler to -Ofast. However, I need to gain mo...

I am using STM32F070 processor. I want to know a way of instructing the NVIC not to execute Timer interrupt in certain cases. Is there a way to do this? The situaltion is as follows-There are two interrupts- SPI and timer conifgured at same priority ...

I am using STM32F070 processor. I want to implement a function where I should measure the time difference between the change of input level on two digital IOs. There is no fixed sequence of the change in level on both the IOs. i.e. any one of the two...

I want to know if the DMA in STM32F070 supports data transfer of 2/3 bytes? Or Does it support transfer only of multiple of 4 bytes?In my project, I have a problem of data alignment. My hardware is receiving 3 bytes of data over UART periodically. I ...

Try to debug with the ST-LINK using a different project. It should work (worked for me atleast). Then again try with the original project.

Perfect. Many thanks.

A bit into the implementation, i noticed that the IO that I am talking about has to be configured in alternate function for TIMx in order to use as capture/PWM input. However, in my case, these pins are already configured as two SPI Rx. Infact I am m...

Thanks. Actually I dont want first interrupt after the first capture as the application has time contraints. But I will see what is possible with timer.

Thanks. I might use the second part of your suggestion as the maximum delay allowed in this case is 25us, beyond which it is an error condition.

Tell NVIC not to exeucte a pending interrupt

Timer measuring time between state change on two digital inputs

Does STM32F070 DMA controller support unaligned data transfer?
