i want to build continuous potentiometer with dma which is sensing wind direction . I have to use modbus because send data on an another STM32F070F6P6 microcontroller, but in the reference manual pdf(page 22) it says we can't work modbus communicati...
I have connected my RS485 automatic hardware flow control with energymeter and with the help of that, tried to transmit the query 01 04 00 21 00 02 (forf voltage) along with CRC check ....uint16_t ModRtu_CRC(uint8_t buf[8], int len){ uint16_t crc = 0...
Hi I am developing a dispenser. The dispenser has a CPU, Keypad, Pulsar and Display each board developed with STM32H750VB. In that I have done the coding for MODBUS in CPU. While the machine is IDLE the MODBUS works correctly and i am able to r...

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...
I want to implement the modbus rtu on the micro STM32L031G4 which library do you recommend?(if you use freeROTS how should I configure the micro da cube ide?)
I ordered a EVAL robot kit-1 from STM and im trying to connect the motor to a MODBUS software. I used ICC MODBUS MASTER application. There is a problem with the holding registers. NO OTHER VALUE than 4 for the Target position in degrees (least signif...
Actually i got the project on modbus but i am trying to code without using libraries but i am not getting expected result. can anyone help me with this and what extra line i need to add in my code please.Thank you
Can anyone help me were can i find the modbus libraries and how to implement in my code.Thank you
