On the pursuit of a lower deepsleep consumption
Sadly even if I tried hard, it was very challenging if not mission impossible to get a deepsleep of 10 uA, eventhough in the MCU datasheet might say that it consumes as low as 1 uA when it’s on deepsleep.And why is that?For a variety of reasons all quite hard to grasp. But the most…
On driving Eink displays
There are 2 different known ways to drive them that are widely known:- SPI epapers, can be driven with this popular interface that is supported from Arduino, to a wide variety of MCUs- Parallel epapers also called einks like the ones that are used in Kindle & another e-readers Let’s start with the most easy…
External Flash IC test on ESP32C6
In last board we send to fabrication the C6 ULP project I’ve failed miserably. Why?The board routing and schematics was Ok! But I’ve wrongly mistaken the ESP32C6 MCU using a 40 pin QFN that does not come with built in flash.You can find the open source KiCad files in this repository.Sadly that is the bad…
Low power ULP C6 PCB
This was a great idea from my friend Larry Bank. But what is the ULP and how can we benefit from it?In Espressif own words: And what are the possibilities to use this small ULP processor while the rest of main CPU sleeps using the smallest possible power consumption? With this points in mind the…
