Generating 1 nanosecond update event using Timers - AN4013
According to AN4013 on using timers as time base generators, one could use a 16-bit timer to generate an update event from a nanosecond to a few minutes. Well, take for example the STM32F429 clocked @ 180 MHz. If one cycle takes 5.56 ns, which is the...
Modbus over RS485 with STM32F303K8
I'm looking to make a loop of MCUs as slaves to a PC master so that I can send commands to them. The idea is to use the https://www.maximintegrated.com/en/products/interface/transceivers/MAX22025.html and https://www.ftdichip.com/Support/Documents/Da...
