MODBUS

Posted by: frasanc - 05-25-2026, 08:39 AM - Forum: KC868-A2v3 - Replies (5)

We have a question about reading Modbus RTU:

With A2:
RS485:
RXD:35
TXD:32

With A2V3:
RS485:
RXD:GPIO15
TXD:GPIO7

With A2 can read, but not with A2V3. Any idea?

// A2v3:
HardwareSerial MBus(1);
MBus.begin(9600, SERIAL_8N1, 15, 7);
pinMode(4, INPUT); // modo auto

// A2:
HardwareSerial MBus(2);
MBus.begin(9600, SERIAL_8N1, 35, 32);

ModbusMaster node;
node.begin(1, MBus);
uint8_t r = node.readInputRegisters(6, 2); // FC04 @ PDU 6

Someone could help us?
