About this deal

Some bootloaders might leave the UART enabled after they start the application, leading to high current consumption. Comfortable and secure fit: The stainless steel band and hidden push-button clasp ensure a comfortable and secure fit. Enable the DC/DC regulator. This doesn't affect the current consumption while sleeping, but almost halves the runtime current consumption. But we’re not here to talk about that today. Instead, we are here to talk about this super cheap brand that does not contain any real diamonds yet has the same style of a bust down watch. It's often better to avoid floating point values on embedded systems and in this case there is no reason to use float at all, we can just represent the value in millivolts. Therefore the formula can be simplified to:

Chip select must be held low while driving the display. It must be high when using other SPI devices on the same bus (such as external flash storage) so that the display controller won't respond to the wrong commands. You’ll want to repeat this method on both immediate sides of the clasp itself as well as for the number of links you want to remove on the other side of the strap. The on board accelerometer in devices shipped before July 2021 is a Bosch BMA421, connected to the I2C bus. The touch panel is controlled by a Hynitron CST816S chips. Unfortunately, there is not much information about this chip on the internet apart from the datasheet below and a reference driver. This is enough to implement a basic driver, but crucial information needed to implement advanced functionalities are missing (I²C protocol and registers, timings, power modes,...).Put the SPI flash in deep power-down mode by setting flash CS high, then low, then writing the byte 0xb9 on the SPI bus, and then setting flash CS high again. Note: The part number for the SPI FLASH in the schematic diagram is not correct, the PineTime features a larger external FLASH device, see below.

While enabled, the button in pin (P0.13) will be high when the button is pressed, and low when it is not pressed.

Leave all pins in their default state, except for P0.05 (SPI CS) and P0.25 (LCD CS) which should be configured as an output and set to high.

If you want to dive in to the ecosystem, here's a short list of various articles and blog posts that can help you set up your soft- or hardware development environment. What you find here in the general build of these watches is nothing special. These are quartz watches, featuring analog displays. The cases are made from metal alloys. Dial windows are typically mineral crystal. Quartz movement: The watch is powered by a quartz movement, which is known for its accuracy and durability. You can be sure that the watch will keep accurate time for many years to come.InfiniLink (iOS) - Companion mobile app in development. Supports updating firmware/bootloader, setting date and time, Apple Music controls, and battery and heart rate data. This one has a much more unique look. It has more of a steampunk aesthetic. Here, the iced out portion surrounds the bezel only. It has the skeleton open display case style, as well as a calendar located at the top. Overall, it’s a good look. It comes in several different color variations. Put the heart rate sensor in sleep mode by setting the PDRIVER (0x0C) register to 0, see the HRS3300 datasheet for details. Pintime watches present true bargain bin pricing. These watches really are dirt cheap, especially compared to other similarly styled brands.
