Old hardware HW_ID=2600:
v55
  - in case of e8r FWID 10, 12 or 13 is detected, after broadcast is sent, host does not send other requests immediately, but waits until all answers received or timeout is fired.
v54 
  - added life counter in IR19
v53 
  - v51 software adapted to work on both chips -> STM32F100VCT6 and GD32F103VC 

New hardware(G) HW_ID=2601: 
bootloader v6(G)  
  - v5 bootloader  ported to new hardware b01_d with STM32G0B0CET6 
bootloader v7(G) 
  - added delay at startup to avoid LCD starting problem 

v60(G)
  - in case of e8r FWID 10, 12 or 13 is detected, after broadcast is sent, host does not send other requests immediately, but waits until all answers received or timeout is fired.
v59(G) 
  - added life counter in IR19
v58(G)
  Bug fixes:
  - fixed error when trying to read MB registers in Multiadress mode
  Changes:
  - removed writing extension manual settings/values to FRAM
  - added delay to init Modbus intefrace function until first extension read cycle will be completed or after 4s timeout(in case no extensions is connected).
    The main reason of this is to fill Modbus IRs with an actual values before the first Modbus access.
  - writing to FRAM is allowed only when measured power supply voltage is over 18V (to avoid memory corruption in case of power interruption during writing operation).
v57(G)
  Bug fixes:
  - system clock settings wern't overwritten after bootloader (bootloader uses reduced system clock frequency).
  New features:
  - added FRAM access logging function (if uSD card with fram.txt file is inserted, at each startup system writes to this file complete FRAM dump
    and logs all FRAM write operations)
  - added FRAM write operation verification
  Improvements:
  - improved Modbus response time
v56(G) 
  - fixed problem that  text does not show voltage(float values) on LCD -> -u_printf_float flag must be enabled 
v55(G) 
  - fixed problem with not working Modbus if lines are wrongly biased 
v54(G) 
  - use xi and  pot buffering in EXTBUS_ProcessHostCommunication() to prevent hardware fault.
v52(G) 
  - v51 software ported to new hardware b01_d with STM32G0B0CET6
