Re: [ts-7000] SPI interface on TS7500

[Razvan-Ionut Stoian <>]

TS7500 does not have a specific hardware SPI port (no hardware pins assigned).

You have to bit bang 3 GPIOs in order to create the SPI port.
(Unfortunately, TS does not specify  this in their docs.)

I am trying to configure SPI interface to use AD converter ( AD 7927).

I am having some following issue

 

1) generate CS# on DIO#11

2) generalte SPI clk whenver SPI read or write command is issued

3) configure SPI as 16 bits data access

4) need to write to SPI reg#48 to configure the control register (select channel, voltage range, power manager) and then read this register to get the AD data.

 

 

I would appreciate if someone can advise me.

 

 

Thanks
