Arduino for STM32

Thank you for the replies. I’m going to try using timer DMA with an external clock. If I can get it to work it’ll be fast enough.

Here's the code I used:


#include <Arduino.h>

HardwareTimer *MyTim;
volatile uint32_t afterMicros;

void Clear() //Interrupt callback
{
MyTim->pause();
}

void setup()
{
Serial.begin(115200); // opens serial port, sets data rate to 115200 bps
while (!Serial) {
digitalWrite(LED_BUILTIN, HIGH ...

Thanks for replying. I suspect something is wrong with the way I'm measuring the cycles. The docs say it should respond in 12 cycles, so 600 is way out of line. I suspect there's overhead added to resolve pins and stash all the states, but it can't be that many ticks. I've been reading about timer ...

Hello,
I'm new to STM32's. I'm using an L432KC to develop for convenience to learn timers and interrupt handling. I'm trying to read an encoder that uses an SSI protocol. I filter the values and send it on via SSI. SSI protocol is a simple clocked serial stream.

I have a couple questions:

1) I ...
