ADB Command Introduction

Focaltech also provides ADB command tuning interface. This is for easier user tuning experience. Related code can be found in focaltech_ex_fun.c.

static struct attribute *fts_attributes[] = {

&dev_attr_ftstpfwver.attr,

&dev_attr_ftstpdriverver.attr,

&dev_attr_ftsfwupdate.attr,

&dev_attr_ftstprwreg.attr,

&dev_attr_ftsfwupgradeapp.attr,

&dev_attr_ftsgetprojectcode.attr,

NULL

};

static struct attribute_group fts_attribute_group = {

.attrs = fts_attributes

};

/*create sysfs for debug*/

int fts_create_sysfs(struct i2c_client *client)

{

int err;

err = sysfs_create_group(&client->dev.kobj, &fts_attribute_group);

if (0 != err) {

dev_err(&client->dev,"%s() - ERROR: sysfs_create_group() failed.\n",

__func__);

sysfs_remove_group(&client->dev.kobj, &fts_attribute_group);

return -EIO;

} else {

mutex_init(&g_device_mutex);

pr_info("fts:%s() - sysfs_create_group() succeeded.\n",

__func__);

}

return err;

}

void fts_release_sysfs(struct i2c_client *client)

{

sysfs_remove_group(&client->dev.kobj, &fts_attribute_group);

mutex_destroy(&g_device_mutex);

}

The produced file will be under /sys/bus/i2c/devices/1-0038/. Under the run line enter cmd, enter adb shell and then enter cd /sys/bus/i2c/devices/1-0038/ .The following introduces how to use ADB commands to fine tune the interface provide by the driver.

1. Enter cat ftstpfwver for current FW version
2. Enter cat ftstpdriverver for current driver version
3. Enter echo 1 > ftsfwupdate to upgrade FW via .i document
4. Enter echo 88 > ftstprwreg to read register value of 0X88
5. Enter echo *_app.bin > ftsfwupgradeapp to upgarde FW via .bin document. *app.bin needs to be placed under /sdcard/_ prior to execution.
