Re: SUB-20 Reset
No,
SW reset is not that simple as it will involve USB reset and USB reconnect. I do not think you really need it.

Re: SUB-20 Reset
GPIO default state is ALL INPUT. You can do it as
Code: Select all
sub_gpio_config ( hndl, 0x0 /*set*/, &config, 0xFFFFFFFF /*mask*/ ) ;
sub_gpiob_config( hndl, 0x0 /*set*/, &config, 0xFF /*mask*/ ) ;

Re: Writing outputs seperately on IC PCF8574
OK,
But how is it related to SUB-20? You should talk to PCF8574 manufacturer.
SUB-20 is only a channel between your PC program and PCF.

Re: Writing outputs seperately on IC PCF8574
OK,
Now tell us in plain English with register addresses and values, what are you doing, what do you expect to get and what actually happens.

Re: SPI data transfer issue
I assume SDI is data from IC to SUB-20 and
SDO is from SUB-20 to IC
If it is vice versa you will need instead SETUP_SAMPLE

Re: SPI data transfer issue
I used this: Clock Phase And Polarity: The LTC6802-2 SPI compatible interface is configured to operate in a system using CPHA = 1 and CPOL = 1. Consequently, data on SDI must be stable during the rising edge of SCKI . It means you can sample on rising edge Data Transfers: Every byte consists of 8 bi...

Re: SPI data transfer issue
Hi. I can not help you more with it. You have all required documentation and data sheets. We can not study IC's that all our customers work with. This is a job you have to do on your own. And we can not teach customers what is SPI or I2C e.t.c... There is a lot of information about it in the net. If...
