Resolved! TIM1+DMA Driven GPIO transmit speed limit

I am using STM32F407ZGT6 and configured the TIM1_CH1 to trigger DMA2 to transmit data through GPIO. Since the protocol is using both raising and failing edges, I need to control both data pins and the clock pin. So the TIM1 is just generating PWM sig...

Resolved! How can UART_Tx impact neighboring GPIO pins?

I have a STM32G071 where, among other stuff, an UART interface an a GPIO input are configured. UART is mapped to PA9 - PA12 (Tx, Rx, CTS, RTS). PA8 is configured as GPIO input mode (no pull-up, pull-down). On the net connected to PA8 is a hall sensor...

How do I make the onboard LED blink with a button press?

I am using the Nucleo-F767ZI board. I have the normally open of the switch wired to 5V.Common is to pin A0 and to R10K then pulled down to GND.When the button is pressed the pin A0 will go from 0V to ~5V.Want to blink LED1 at say 1Hz, then when butto...

ART Accelerator allowing 0-wait state execution

On an 'F4, I was working on a lengthy piece of floating-point calculation, and had to benchmark it, so I thought I'd share some of the results. Basically, this is a linear calculation with moderate amount of constants and quite liberal amount of sinf...
