Phil Howard aeceefea59 VL53L5CX: Sideload firmware from user-supplied .bin 2022-05-17 12:33:07 +01:00
Phil Howard 8e1e9df002 ST7789: Refactor and Bugfixes 
* Make ST7789 accept only full config with SPI pins
* Make Generic ST7789 wrapper library handle "slot"
* Update Round LCD and 240x240 Square LCD
* Remove Python Round LCD and 240x240 LCD modules (we need the space!)
* Remove C++ Round LCD and 240x240 LCD libraries (they're a little redundant!)
* Fix garbage collected framebuffer bug in Python ST7789
* Deprecate "flip" in favour of "configure_display"
* Tidy up ST7789, remove dead/unused/commented code

Phil Howard 4d33649cd2 HUB75: More rational DMA/PIO setup/teardown, fixes reset bug 
Defensively tear down DMA/PIO so it's in a known good state upon (soft)reset.

Issue was a race condition with DMA interrupts firing and not being achknowledged, leaving a stuck raised IRQ.

The blocking wait for DMA transactions also exacerbated this, turning a borken DMA interrupt and blank screen into an unrecoverable hardlock.

...not that the blank screen was recoverable without a soft reset anyway!

Switch from 12-bit to 10-bit gamma to fit RGB into a uint32_t. Simplifies PIO and halves the RAM usage for F/B buffer.

Switch "flip" to *literally* swap the front and back buffers, and then asyncronously DMA the new back buffer into the front ready for the next draw.

Chris Blume 261d2732f0 Improve ST7789 frame rate ~4x 
The ST7789's Tscycw (time between serial write clock cycles) is
16 ns. This can be found on page 44 of the datasheet I'm using:
https://www.waveshare.com/w/upload/a/ae/ST7789_Datasheet.pdf

(I do not know which manufacturer Pimoroni products use and if
their parts might be different. But it seems like this wouldn't
change.)

The existing code sets the SPI baud to 16 * 1000 * 1000. But baud
is Hz, not seconds. That 16 * 1000 * 1000 doesn't represent 16 ns.
It represents 16,000,000 Hz.

16 ns * (1 Hz / s) = 62,500,000 Hz.

This commit changes the baud from 16 * 1000 * 1000 to 62'500'000,
representing ~4x speed improvement in SPI and thus ~4x frame rate
improvement, since the display's frame rate is currently
SPI-limited.

A before & after video can be seen here:
https://www.youtube.com/watch?v=n2y19TCnATo

Note that also on page 44 of that datasheet Tscycr (the read speed)
is only 150 ns, not 16 ns. Right now, the Pimoroni code doesn't read
any values back from the ST7789 so it is safe to operate at the
higher speed.

Also note that the 16 * 1000 * 1000 is the requested baud. The actual
baud is the closest the Pico can get, which is 15,625,000.
The new requested baud of 62'500'000 results in an exact match.

This covers an edge case where pixels are updated intermittently - such as the once that happens when clearing before a Python soft reset.

Under normal circumstances users should `start` the LED strip and allow it to continuously update.

Phil Howard 2cc6514583 Slow set/clr_bit writes a little 
We chased a bug with handling/clearing interrupts on Encoder into the depths of madness, finding that a Debug build would magically fix the bug.

Turns out it was probably just us being a little aggressive with the poor little MS51-based Encoder driver.

* Fix delays to be more delayey.
* Replace big 'ol loop and boolean with straight up checks and an early exit- the bit-addressed regs are never going to change

Phil Howard 53429e0c6f Do not pio_sm_unclaim for MicroPython 
Adds an ifdef guard around `pio_sm_unclaim` that prevents it being called when MicroPython cleans up/finalizes classes.

For some reason this appeared to be causing a hardfault.

Phil Howard 815e784625 Plasma 2040 library & examples 
Library:

Includes classes for driving WS2812 and APA102 LEDs and defines for Plasma features.

Encoder Example:

Supports connecting a Rotary Encoder via the Qw'St connector.

Works with APA102 or WS281X pixels.

Pressing A will cycle between:
1. Colour change
2. Brightness change
3. Cycle delay

Pressing B will switch back into auto-cycle mode.

Turning the encoder at any time will switch out of auto cycle mode into parameter adjust mode.

Also includes a bugfix to Rotary Encoder for getting the interrupt correctly.

Rainbow Example:

Basic rainbow cycle, press B to speed up and A to slow down.

Two BME688 examples are available for forced-mode and parallel-mode operation.

Fix Pico Explorer SPI for #162
 2021-06-05 19:17:16 +01:00
Phil Howard 6022928517 Fix Pico Explorer SPI for #162 
The switch to common I2C and common definitions for SPI had broken an edge case in Pico Explorer where no backlight pin is used.

The backlight pin was inadvertently set to the front Breakout Garden SPI slot default, which is pin 20- this also happens to be the I2C SDA pin for Pico Explorer, breaking I2C comms.

This fix adds a new special case board "PICO_EXPLORER_ONBOARD" so that ST7789 can be initialised without the backlight pin.

This will be useful for anyone using ST7789 without the rest of the Pico Explorer library, although it feels a little contrived.

Also switches ST7735 over to the common defines.

Confused myself by plugging this into a BG base. It gave all the appearance of working, but the time was not counting up.
Turns out the library will happily talk to no device whatsoever and when you "set_time" it's stored in an C array and returned as if it came from the RTC.
