Oresat-notes

Note) Looks like a command shell is realized in code near end of file:

   psas/oresat-firmware/src/f4/app_control/source/command.c

Note) ina226.c and other device type driver source files in 'psas/oresat-firmware/common' give examples of I2C calls in ChibiOS environment.

INA226_SHARED_I2C

Example file which calls an I2C init function among other things, in routine app_init():

 oresat-firmware/src$ vi ./archive/f0/app_solardemo/main.c

   /*
 * I2C configuration
 */
static const I2CConfig i2cfg1 =
{
    I2C_100KHZ_TIMINGR,
    0,
    0,
};

uint8_t data[8];

static void app_init(void) {
    //=== App initialization

    // Start up debug output
    sdStart(&SD2, &ser_cfg);

    i2cInit();
    i2cStart(&I2CD1, &i2cfg1);

    for (uint8_t i = 0; i < 8; ++i) {
        data[i] = 0;
    }

    canTPDOObjectInit(CAN_PDO_1, CAN_ID_DEFAULT, 0, 0, 8, data);
}
