Discussion - Drivers / FT4222_SPIMaster_Init issue when using other ssoMap than 0x1
« on: February 09, 2021, 05:52:02 PM »
According to the documentation, if I understand correctly, these are the values I should send for slave selection SS0 -> 0b0001, SS1 -> 0b0010, SS2 -> 0b0100, SS3 -> 0b1000, but, only the option for SS0 is working, the others return an FT4222_INVALID_PARAMETER error, however, sending any combination with the lsb in 1 (0b0011, 0b0101, …) does not return any error, however, only SS0 works in those cases.
Following is my spiMaster_Init configuration:

ioLine : SPI_IO_SINGLE
clock_div : CLK_DIV_4
cpol : CLK_IDLE_LOW
cpha : CLK_LEADING
ssoMap : 2 (0b0010)

Can't see if I'm doing something wrong or what I'm missing.

Discussion - Drivers / FT4222 more than 8 bit data frame / python drivers
« on: January 15, 2021, 02:15:34 PM »
Hi, I'm trying to make an interface in python, first of all, if someone knows of a package (other than python-ft4222) or an alternative library to Libft4222 from FTDI (they already answered me that this library does not have the functionality I require), please tell me.

For the frame data, I require to communicate with a ADS1118 temperature sensor, which requires minimum 16 bit data frame, as told by FTDI reps, Libft4222 (therefore, also python-ft4222) only operates at 8 bit data frame, so I'm getting a "gap" in between each byte. Does someone know a workaround to get at least 16 continuous bits?

Thanks in advance.
