This is the source repository for godafoss, a micro-python library.

To work on the sources, clone this repository (wovo/godafoss-code, not wovo/godafoss) and copy the godafoss directory to your MicroPython device.

lcd_spi_cd.py should be spi_cd.py

where does sleep() come from??

• lcd has too many parameters
• sort lcds and boards alphabetically before inserting
• mention using a powered hub for 4.1
• make/build and make/load commands
• iets weirds met links, maak er een $$class() van
• generic_lcd afmaken
• more lcds https://luma-lcd.readthedocs.io/en/latest/ https://www.espruino.com/Graphics?print https://github.com/rm-hull/luma.lcd/blob/master/doc/python-usage.rst

ESP32 generic spiram on sunton_esp32_2432s028 has no effect at all on board with soldered spiram? (not even crash)

build & load arguments separate, any order target, gf, nogf, spiram, octal, baudrate

time the downloads pause at end of .bat is useless

TODO

• demos are not part of the download, and not part of the website

• how usefull is the splitting for a frozen lib?

• sources no longer fit on a pico :(

• Traceback (most recent call last): File "", line 2, in File "godafoss/g/edge.py", line 52, in edge File "godafoss/init.py", line 166, in getattr File "", line 1, in ImportError: can't import name _edge_esp32
  doesn't work on .py sources either...

• esp8266 build, try with built-in!

• esp32c3 build

• esp32 build - works!

• pico-w build

• esp32c build

• examples in documentation refer to the old test

• sphinx warnings

• avoid using micropython directly?

• complete introduction build & install

• adc example & test to tests, change import path to root

• add RAM & startup metric to all demos

• suppress base: object

line buffer 240 * 2 = 480 bytes each call 320 calls
10 MHz 1.51 ms 20 MHz 1.45 makes sense: 2404808/20M = 0.06 s without the write_command calls 1.33 ms

• avoid the * 1.30 s
• twice the pixel retrieve 1.7 s once, no write, avoid *, micropython.native 812 ms (viper doesn't work, maybe works on the smaller section) still native, once, explicit loop instead of range 814 ms

python, range, avoid *, write_cmd( buffer = ), line buffer, 20 Mhz 1413 ms breaks down: pixel retrieve line 400 ms write_command 120 ms

python, 20 MHz
for b in self._buffer: self.write_command( None, buffer = self._pixels[ b ] ) 1.58 ms self._spi.write( self._pixels[ b ] ) 687 ms
idem native 680 ms zonder native, array index out of the loop 670 ms idem, 2 spi calls 1318 ms -> spi calls now take all time make the spi calls transfer 2 x the data longer _pixels 821 ms (same as -> 10 MHz) p + p 995 ms

30 MHz 687 ms 20 MHz 691 ms 10 MHz 820 ms

(er wordt iets te veel geschreven - waarom??)

accummulate byte array 1 1214 2 753 4 (64) 690 (varies a lot)

idem single allocation 1 (16) 970 2 713 4 544 8 464 16 444

This is promising, continue with the 16 base 445

• 2 x spi_write -> 550
• 2 x copy -> 541
• @native -> 398
• separate _send@native 398
• some const 311 !
• viper crashes
• python 355, native 312
• native, copy twice 490
• native, spi twice 417

native, ms, copy to temp 1: 779 2: 529 4: 382 8: 318 16: 311 -> avoid lookup 301 32: 361 (??) 128: 771 - copy twice 14482 - spi twice 839
