Hello everyone,
I need your help with the SPI network and the mcp chips,

with codesys, I use eight chips mcp23s17 and it works perfectly now, :D
I now want to add a chip mcp3008,

for mcp23s17, we assign an address to each chip,
first, is it necessary for the mcp3008 chip?
because it does not appear in the datasheet. :?

second, can we put one mcp3008 and several mcp23s17 on the same network?

in third, is it possible to place two mcp3008?

thanks for all help
