Multiple GPIO configurations

[sridhartagv]

Hi Everyone,

In the following code, i’m having trouble to Subscribe multiple gpio’s.

Please do verify the code and comment.

Hiya,

First, PLEASE use the CODE tags to format your code when posting - it makes it much easier to read.

Your code is returning the error code ‘-11’ from all the subscriptions bar the first one. Looking up the ADL API guide, Error -11 is ‘ADL_RET_ERR_DONE’, which the adl_ioSubscribe() doc indicates that you have to look up the adl_ioError_e type.

Doing a bit of maths on your result (20000000) gives the error ADL_IO_ERR_USED - which indicates that the GPIO pin is already used by another section of the Q2686RD.

Moving to the Q2686RD Product Technical Spec (PTS) indicates that GPIO[8:4] are nominally configured as Keypad column drives [4:0], and GPIO[9:13] are keypad row drives [0-4].

The keyboard is enabled by default in a Q2686 modem - so OpenAT cannot access the GPIO assigned to the keyboard.

You have two options:

1. Move your I/O to different pins (after having a careful read of the PTS);
2. Disable the keyboard using the AT+WHCNF command.

Two things to learn here:

1. Examine the error results VERY carefully - and reference back to the API doco (and PTS if you’re doing hardware design).
2. Read the API and PTS doco VERY carefully - and read ALL of it, not just the function you are using at the time. Although, do be aware that some of the examples haven’t caught up with the API changes…

ciao, Dave

p.s. Don’t forget to use the CODE tags next time you post example code…

Hi,
David

Well i’m able to subscribe for the required GPIO’s and GPS data is available on UART.

i’m learning to read the error results according to the document and work. I’m not familiar with this portal, so, i’m not able use tags. From next i’ll definitely use the tags.
