The rest is done in software, no really 'hardware tricks' required. Modbus ASCII is especially trivial to implement. RTU and it's timing requires some more brains. Just get the specs from http://www.modbus.org,

WebThe bit field will be unsigned with gcc and clang, but signed with VC++. This means that in order to store zero and one you need a two-bit bit field (a one-bit signed bit field can only store zero and negative one). Then you have to worry about packing. VC++ will only pack adjacent bit fields into the same backing store if their sizes match. WebNov 17, 2024 · Here, open the Makefile and pick any of the board presets (currently Blue Pill, Nucleo-F042K6, STM32F4-Discovery or Nucleo-746ZG).

WebDec 11, 2024 · Especially on the smaller STM32’s, the 32 bit timers can be non-existent, or scarce. If you’re running from a 12-16 MHz internal clock, the 16 bit timer doesn’t give you much of a delay ... Websetting a bit or clearing a bit requires two memory accesses on ARM (not talking about bit-banding here): read a word + modify it + write the modified word. Concurrent modifications, e.g. from main and an interrupt handler of the same word may result in unexpected results (race conditions).
