Hi everyone.I am sending string data from PC and I want it get with UART of STM32F1xx but as you know I can only have 1 character.For example I am sending "234" as a string from PC, but I can see only ascii character of only 2 (ascii code of 2 is 50)...

hi, i am new to stm32, i want to use modbus in my stm32f103 to read , read and write the commands in both register mode and coil mode. I searched for modbus libraries but i found nothing .

Can anyone help me were can i find the modbus libraries and how to implement in my code.Thank you
