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. No these won’t fool anybody up close, but from a distance, and in passing, they do have the glitter and luster of a bust down watch. Definitely not bad for a watch that has no real diamonds in it. Today we will be looking at yet another brand that has surfaced on the online marketplaces. This time we are going to review Pintime watches. If you came here to find something that had the style of an iced out watch, then you will not be disappointed. For what you are paying, you get the styles of frosted diamond encrusted watches, at bargain prices.

The HRS3300 sensor is enabled on power on. Write byte 0x00 to the PDRIVER register (0x0C) to set it in sleep mode. 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: Touch information is available from the 63 first registers of the controller. Remember: the device is in sleep mode when no touch event is detected. It means that you can read the register only when the touch controller detected an event. You can use the Interrupt pin to detect such event in the software.

The display is driven using the ST7789 display controller. Use the following pins to drive the screen: Gadgetbridge (Android >= 4.4) - Companion mobile app, supports updating firmware/bootloader, send notifications, etc.

NOTE: The I²C bus, also known as TWI bus, has known issues, make sure to write your TWI driver with timeouts. The PineTime uses a standard 20mm watch band / strap. There is a thread in the forum discussing this. It appears that under some configurations, edge triggered interrupts result in a large power drain. One way to avoid this is by using the pin sense mechanism. SLEEP (reset the touchpanel using the reset pin before using this register: pin_low, delay 5ms, pin_high, delay 50ms then write 3 to register 0xA5) Iced out”, or also known as “bust down” watches refer to watches that are encrusted with diamonds. These styles have become popular among celebrities, especially in the world of hip hop.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. Reading the battery voltage is a bit harder. For that you can use the battery voltage pin on P0.31 (AIN7). The returned value is 12 bits, which means it is 0..4095. You can get the measured voltage with the following formula, assuming a reference voltage of 3.3V (this is configurable in the ADC):

Luxurious and sporty design: The watch has a unique and eye-catching appearance with a diamond CZ embedded in the dial. It is perfect for everyday wear and can withstand splashes and brief immersion in water. 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.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. PineTime/InfiniTime needs a companion app to e.g. upload a firmware, get notifications from a phone, or just get the date/time. Note that the button consumes around 34µA when P0.15 is left high. To reduce current consumption, set it to low most of the time and only set it to high shortly before reading it. The button needs a short time to give good outputs though, setting P0.15 high at least four times in a row seems to result in enough delay that P0.13 has a stable output. Sleep in a loop, using WFE or WFI (if you're using the Nordic SoftDevice, call sd_app_evt_wait instead). There is not a whole lot amazing going on with these builds. Clearly, these are not, by any means high end watches. they are decent, however, for being such low priced timepieces.

NOTE: The controller goes to sleep when no event is detected. In sleep mode, the controller does not communicate on the I²C bus (it appears disconnected). So, for the communication to work, you need to tap on the screen so that the chip wakes-up. In terms of style, these do hit the mark, and they do present the look that they are going for. Just don’t be surprised if they give away their real value upon closer inspection.

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. Amazfish (SailfishOS and Linux) - Companion mobile and desktop app, supports updating firmware/bootloader, send notifications, etc.
