  • Fixing NoIR focus issue
  • Log     from Automatic Reading Machine
  • We were able to adjust the camera's focus by rotating the lens of the module using a needle nose plier, as mentioned in this tutorial.The texts present in the images are now much more readable.

  • Release 0.25.0
  • Log     from zeptoforth
  • This release adds true symmetric multiprocessing support for the Raspberry Pi Pico (RP2040). Now can tasks on different cores not only share and communicate across cores for multitasking communication and synchronization constructions such as semaphores,...

  • Release 0.28.0
  • Log     from zeptoforth
  • This release removes significant limitations on multiprocessing on the Raspberry Pi Pico which had been caused by heavy sharing of hardware spinlocks across synchronization/communication constructs longer than absolutely necessary, significantly optimizes...

  • Release 0.30.0
  • Log     from zeptoforth
  • This release significantly optimizes the speed and memory footprint of constants (literals and long calls) in the RP2040 (Raspberry Pi Pico) platform. It also changes task queues, used by semaphores, queue channels, and byte streams, so they favor readying...

  • Release 0.42.0
  • Log     from zeptoforth
  • This release adds one-shot ADC support for the supported platforms. It also adds an optimization to compilation for the RP2040 (Raspberry Pi Pico). Note that there is a notable erratum for the STM32F407, STM32F411, and STM32F746, where when at least...

  • Patch-level release 0.59.1
  • Log     from zeptoforth
  • This patch-level release fixes a major bug in local variables in nested quotations, adds creation/modification date/time support (using the realtime clock on the Raspberry Pi Pico) to the FAT32 layer, adds minimal stubs for date/time handling to platforms...

  • 3D Printing the Tray
  • Log     from APC UPS NMC from a Pi
  • I've been tweaking the 3d printable design for the tray. Tabs and panel cutouts fit a Raspberry Pi 1, but can easily be adjusted for any model. I've also included a way to hold a piece of PCB in place, so it can slot directly into the card edge reciprocal...

  • Adding isolation
  • Log     from KNX Raspberry Pi HAT
  • A new schematic is available under ncn5100rh-2. This is the new design which will contain functional isolation between the KNX transceiver and the Raspberry Pi. The design is available on the GitLab project page.I will be working on the layout for this...

  • Build a more complete interface
  • Instructions     from PlayVideo: adaptive video player
  • Go to this web page and see how to build a complete interface for the Raspberry Pi.  https://arm22q13.wordpress.com/davids-video-player/ There are essentially two versions. The simpler one is for wired adaptive switches. The more complex one...
