Freescale Geomagnetic sensor MAG3110 Debug notes

First, we need to understand a basic concept: the geomagnetic sensor must work with the gravity sensor, and the compass will work properly.I. Key points for commissioning:1. The gravity sensor has a directivity of 3 axes, and the data output of the geomagnetic sensor is also directional. We must configure the correct position according to the position of the relative LCD view of the hardware Layout board sensor to indicate the correct orientation.2. Mag3110 driver in the Linux bottom register, i

Freescale has been acquired, $40 per share! The semiconductor industry is full of smoke!

This year's merger and sale of the semiconductor industry have just ended, and they have just begun. First, the split of PHILIPS semiconductors, which was widely spread at the beginning of the year, was completed last month. Then, Intel sold the Non-Profit department twice, which can be described as a scissors. Now, Freescale, just two years after its independence from Motorola, was acquired by a consortium at a price of $17 billion, which is $40 per

How to configure the gpio of the feisikar imx6 Processor

In Linux or android systems, if we want to configure the gpio pin of the feisikar imx6 processor, for example, the gpio_19 pin, we should look like this: #define MX6Q_PAD_GPIO_19__GPIO_4_5\(_MX6Q_PAD_GPIO_19__GPIO_4_5 | MUX_PAD_CTRL(NO_PAD_CTRL)) _ Mx6q_pad_gpio_1920.gpio_4_5 is defined: #define _MX6Q_PAD_GPIO_19__GPIO_4_5\IOMUX_PAD(0x0624, 0x0254, 5, 0x0000, 0, 0) The iomux_pad macro is a key macro defining gpio. Its prototype is: #define IOMUX_PA

About IMX6 Core Board QT system USB Stick mount
