Hello people ,
we need some help from ST for solving the ST7538-Q interfacing with SPI .I don't even no where I have to ask the question .currently I am working in powerline communication using st7539-q and we are trying to communicate ST7538 -Q via SPI interface using this pins
RX( MOSI)...
Hi Carry for cents bazar,
actually finished the configuration correctly after that I am getting output on ATO,ATOP1 and ATOP2 also voltage levels at the pins ATO =1V,ATOP1 and ATOP2 = differential signal and 2V .all are fine .having one doubt .I am sending a data 11 00 11 00...
and also we are using opto-coupler for isolating the GNDS. Isolator placed between TTL logic and modem tx and gnd. LED anode pullup with the
TTL supply. LED Cathode connected to Rx of TTL .Transistor (collector)side pull up with ST7538-Q 5V supply and emitter ground. Its is working perfect for...
Thank you for the reply ,
actually it is connected properly and all in default configuration .we didn't change anything .we are are trying to communicate via UART mode in internal register set default UART But in schematic (pin 13) externally pull down .so we lift the pin configure the...
Hi people ,
here I am using ST7538-Q When i try to transmit the data the module doesn't responding all the power are perfectly doing their workI am working in asyc communication .ATOP PIN TO GND SHOWING 5V . and CL pin 0V FEED BACK VSENSE PIN SHOWS 0V .what i do
