Driving a Large E-Paper Display with a Compact MCU Board

4/22/2022

 
How to drive a large e-paper display in a small form factor?

E-paper displays require an external frame-buffer, hence the need for a large SRAM. For example, the Pervasive Displays 9.7" black-white-red e-paper display 960x672 requires 161280 bytes.

​Recent MCUs pack or drive large amount of memory, like the Raspberry Pi RP2040 used in the very compact Seeed Xiao RP2040 board.

​Discover the project.

Review of the Nordic Power Profiler Kit II

4/20/2022

 
One of the most critical challenge of embedded systems is managing the power budget. And very often, measuring power consumption turns into another major challenge.

Nordic comes with an interesting option: a universal ammeter with 8 logic inputs, with a dedicated application running on Linux, Mac and Windows.
