Bitfile for Mesa 7i96s + 7i85 (+Modbus (PKT-Pin)) was created by TripleM
Hello,
My current configuration consists of a 7i96s and a 7i85. A 7i84 is connected to the 7i96s via Smart Serial.
By default, I can flash the original bit file "PIN_7I96S_7I85D_51".
Now I would like to add a PktUART pin for Modbus. Is it possible to connect Modbus to the 7i85, or is that only possible directly with the 7i96s?
My suggestion is attached, but unfortunately, I'm not sure if it's correct.
I've added the following to the first block:
If I link the pins to the 7i85, does that mean I'll use two Smart Serial pins?

(PktUARTTTag, x"02", ClockLowTag, x"01", PktUARTTDataAddr&PadT, PktUARTTNumRegs, x"00", PktUARTTMPBitMask),
(PktUARTRTag, x"02", ClockLowTag, x"01", PktUARTRDataAddr&PadT, PktUARTRNumRegs, x"00", PktUARTRMPBitMask),If I link the pins to the 7i85, does that mean I'll use two Smart Serial pins?
