Hi all,I've a board with the STM32F103C8T6 MCU.My firmware has to handle a lot of IO, display and UART logic, nothing special but just a lot of logic.So the 64K b internal flash memory is almost full.I've a couple of question here:1) can i switch to ...

Hello,I'm working on a project involving an STM32F103 and a mcp23017 port expander.I've connected the mcp23017 INTA to PA15, no pull-up or down involved.I'm able to drive the mcp23017 via I2C, no problem about that.The problem I have is detecting the...

Hi all,I'm using a Timer in Encoder Mode on STM32F103, using the HAL framework on STM32CubeIDE.I would like to change encoder filter feature (IC1F[3:0]: Input capture 1 filter) depending on the behaviour selected in my MCU operation mode (so IC1Filte...

Hello,I'm working on a STM32 project which use the timer in encoder mode.TIM2 of my STM32F103C8 is set in Encoder Mode, I've enabled the TIM2 global interrupt.I'm evaluating the counter at each interrupt.Prescaler is 0, Counter Period is 65535.Main c...

I'm working on a board design with a STM32F103C8. First time for me to build a PCB with STM32, I've always worked with "blue pill" boards.Not sure about BOOT wiring. The firmware will be uploaded using STM32CubeProgrammer. The board should startup us...

Thanks!

Thanks, so it's a yes on my request "1)", no issues replacing with STM32F103CBT6.

My mistake,I've now realized I do not read the GPIO* registers after initializing the interrupt, this way the firmware enter a states where is expect falling and does not reset the mcp23017 that is now active low and waits for the reads of the GPIO* ...

Hello GOmon.1,I'm using the macro below, which sets the CNT register of the timer instance to zero__HAL_TIM_SET_COUNTER(&htim3, 0);

I've tested and I can confirm changing the filter and polarity works without de-initialization. So updating the filter and polarity bit of htim->Instance->CCMR1 and htim->Instance->CCER works.I would like to change the Clock Division too, so change t...
