Wonder if you can shed some light on this please i will try and explain I'm also using some software to test the data i'm sending is correct then using FC8 and ST-ARM to send the same data. On serial monitor software i send an hex string (highlighted one is the manual string sent) the none highlight...

Thank you i will take a look

Hi Can anyone help out and explain please. I am working with modbus RTU master and flowcode 8 i send a question and get a response the question is correct and crc is correct. The question expects a response but how do i process this response ? I guess i should be using GetResponce() i read the expla...

Thank you! :D That did the trick. #if (MX_UART_CHANNEL_X > 0) /* Enable USARTx clock */ MX_UART_CLOCK_X(); MX_UART_HANDLE_X.Instance = MX_UART_USART_X; MX_UART_HANDLE_X.Init.BaudRate = MX_UART_BAUD_X; ////////////ADDED CHANNEL 3 FOR EVEN PARITY//////////// #if (MX_UART_CHANNEL_X == 4) MX_UART_HANDLE...

OK some news by changing to EVEN it did not help but by also changing 8B to 9B and to EVEN it worked ! but i have a new issue i also have a display connected to a different UART and i guess this is parity NONE so as you may of guessed now the display will not talk to the ST-ARM Any work around for t...

Thank you. Just tested Leaving the parity as NONE in the STARM_CAL_UART.c I the monitor the coms on the 9 way’D application set to NONE a good result SENT IS 01 05 00 01 ff 00 dd fa Setting the parity as EVEN in the STARM_CAL_UART.c I the monitor the coms on the 9 way’D application set to EVEN The b...

Anyone any ideas or comments please.

Thank you.

Hello Is there a way to change the default modbus setting Data bits / Parity / stop bits. What is the default settings ? as i can only seem to find and change the baud rate. My slave only allows the configuration of multiple speeds but with fixed: 1 / 8 bits / Even I think this is my reason why i se...
