Hello,
With updated ModbusMaster component http://www.matrixtsl.com/mmforums/viewt ... bus#p73930 my project with Modbus and I2C MCP23017 works fine on Flowcode v6.
In Flowcode v7 MCP23017 not working.
Any ideas? Thanks!

Hello, Please help, mcp23017 test program works fine on Flowcode v5 and v6, but hasnt work on v7, Program stop working after I2C master component macro TransmitByte. Simulation in console show that all ok. I use PIC18F2620, v6 program works fine. New patch for Flowcode7 today installed, no result fo...

Hello,
I found working example
http://www.matrixtsl.com/mmforums/viewt ... bus#p76164 Example3 and understand, but my logic understanding was wrong
Thank you!

Hello, I has checked all Read from slave functions (ReadHoldingRegister, ReadInputStatus, ReadCoilStatus) and I hasnt it working. Locally in slave ReadCoilStatus works fine, but all remote read functions not work.... The same Master program on Flowcode 6 works, but veeery slowly, one TX per 4sec :) ...

Hello, set to 1 not working too... Master just havent read a Holding register values. I just tried to put a fixed value 0x1f to Holding register address 0 in Slave side. No change, output zero Master side translate address 0 to 40001, 1 to 40002 etc... As the slave side do the same? In ModbusSlave p...

Sorry, but have problem with adc.... my test program steps: --read analog value adc0 --write to register SetHoldingRegister addr0, In ModbusSlave parameters Register aadresses starts with 0 Master side: --ReadHoldingRegister slave id28, register address0, count0 And answer zero.... Maybe any problem...

Thanks! Now example Master-Slave works fine. But I am confused with reading analog input... What way is ok? 1. --Use ADC component and read adc value adc0_read. --Write this value to holding register with SetHoldingRegister with address 1 and value adc0_read. --Master read the register state (slave ...

Hello, I have some expirience with Fc v6 and just purchaced Flowcode v7 because need to make devices with Modbus connectivity. Question, have Modbus component any restrictions for choosing PIC microcontrollers? In attachement my small flowchart for testing Modbus master component, my testboard have ...

Hi, Sorry for this question, but I cant understand, how works logical operations with HEX. https://courses.engr.illinois.edu/ece390/books/artofasm/CH01/CH01-2.html was helpful, but.... MasterNode send address 0x101 and 0x000, in SlaveNode1 I see (RxVal AND 0x100), after this Address check (RxVal AND...

Thank you answer! I have Flowcode v5 My project attached, backled control made as separate macro poweron_sw. AC_DC_check macro is a logic for testing and choosing supply input. It give too additional delay 500ms to main program. If it is possible, main program will work without this delay. System lo...

Hi all, Sorry for my poor English, I am new Flowcode user. I need to make a power supply control unit with 4 adc for voltage measurement, lcd display to show voltages and any logic for switcing load to power sources. ADCs, and lcd works good, but I have problem with any additional functions. They lo...
