Hello, I would like to know if it is possible to measure the length of a really long and thin copper wire. The length ranges between 5 - 15 km. I think TDR (time domain reflectometry) would be the best method for it. My plan is to generate a pulse wi...

I bought a B-L072Z-LRWAN1 with STM32L072C7 as the processor and a NEO 6M GPS module. I found a library on this site https://stm32f4-discovery.net/2014/08/library-27-gps-stm32f4-devices/ Is the TM STM32F4 GPIO Library compatible with my board?

why 200ps per inch? A resolution of 10m would be enough.

Thank your for your answer. So I would generate a PWM signal (3 µs pulswidth) with an amplitude of 12v?Buffer the signal back to 3.3v level. And capture it with a timer. But I dont understand what you mean with "You'll need a fast driver, something t...

Measure cable length

Is a STM32F4xx library compatible with STM32L072C7?

Hello, I am trying to send sensordata from my STM32 Board via LoRa to a PC/Raspberry. What would be the best way to do this? Can I use the free lora gateways registered in thethingsnetwork with stm32?
