Where can I find the A9Gs RDA8955 datasheet in english? #292

SDK_VERSION: V2.112

I am hoping to develop code to run on the A9G using Rust. Maybe port FreeRTOS for use with Rust on the device.

Also, can the A9G module and this SDK be used in a production environment? I am working on a large project that may end up needing about 30K A9G modules. The code encompasses both GPRS and GPS functionality as well as frequency sampling using the available GPIOs. Someone stop me if it is a mistake.

Lastly, can all the pins included in the Power_Type_t enum perform both input and output functions or is it only pin 0 - 7?

typedef enum{
    POWER_TYPE_VPAD = 0,            // GPIO0  ~ GPIO7  and GPIO25 ~ GPIO36    2.8V   //always on
    POWER_TYPE_MMC,                 // GPIO8  ~ GPIO13                        1.9V
    POWER_TYPE_LCD,                 // GPIO14 ~ GPIO18                        1.9V
    POWER_TYPE_CAM,                 // GPIO19 ~ GPIO24                        1.9V
    POWER_TYPE_MAX
}Power_Type_t;

'm sorry we don't have the A9Gs RDA8955 datasheet in english.You can run the example(./demo/gpio) to see which pin you can use.

do you have the rda8955 datashet in other language?

How is VIO Used ? If I want to Connect DHT22 working at 3.3V, Can I Connect the Data Line to - say IO1 ?

Can I Connect VIO to 5 V and then use a 5V Interface ?

Yes having the A9G documentation in English would be great ;-)

@cryarchy it looks like the only alternative to the native C SDK, is micropython. Which given how much power the A9G CPU has, should make it quite awesome.
