Releases: zapta/simple_stepper_motor_analyzer
Firmware release 1.0.4
Mechanical Release (Enclosure) V1.3
Includes the latest enclosure models for 3D printing. Two version are available, a simple that that uses self tapping threads and a more involved one that uses heat set metal threaded inserts. Both use the same M2.5 x 10 hex cup screws.
The small jig is used to trim the stepper motor connector pins to 1mm in length to have a flat surface on the TFT side of the PCB.
Firmware release 1.0.3
Firmware update instructions:
- Press and hold the button at the back of the Analyzer while connecting it to a computer via USB cable. This will cause a new disk drive named RPI-RP2 to appear on your computer.
- Download the .uf2 file of this release into that disk drive. This concludes the firmware update.
In this release:
- Added a brightness control slider in the Settings page (accessible from the Home page).
Firmware release 1.0.2
Firmware update instructions:
- Press and hold the button at the back of the Analyzer while connecting it to a computer via USB cable. This will cause a new disk drive named RPI-RP2 to appear on your computer.
- Download the .uf2 file of this release into that disk drive. This concludes the firmware update.
In this release:
- Speed Gauge, Steps Charts and Retraction screens now sample their data using a hardware timebase rather relying on a software timer. This makes them insensitive to screen rendering latencies.
- Sped up the screen update by using DMA and dual rendering buffer.
- Reduced power up to first screen time.
- Added minor division lines to the Current Patterns and the Phase Patterns screens.
- Minor code cleanups.
Firmware release 1.0.0
Supports Pico based boards with 8bit parallel TFT path and PIO data transfer. Current hardware version 1.00.
Hardware release 1.00
Enclosed Gerber, BOM and SMD position files to order from JLCPCB with SMD assembly service. Does not include current sensors, stepper connectors and Raspberry Pi Pico which are soldered separately.
