action for command 0x022 are (more or less guessed)
bit 7: Enable Clock
bit 6: Enable Charge Pump
bit 5: Load Temparture Value (???)
bit 4: Load LUT (???)
bit 3: Initial Display (???)
bit 2: Pattern Display --> Requires about 945ms with the LUT from below
bit 1: Disable Charge Pump
bit 0: Disable Clock
issue #347
2017-09-08 15:05:44 +08:00
Disable Charge Pump and Clock require about 10ms
Enable Charge Pump and Clock require about 100 to 300ms
issue #318
2017-08-27 00:09:18 +08:00
Notes:
- Introduced a refresh display message, which copies RAM to display
issue #347
2017-09-08 15:05:44 +08:00
- Charge pump is always enabled. Charge pump can be enabled/disabled via power save message
issue #318
2017-08-27 00:09:18 +08:00
- U8x8 will not really work because of the two buffers in the SSD1606, however U8g2 should be ok.

LUT for the 296x128 device (IL3820)
LUT (cmd: 0x032 has 30 bytes)
section 6.8 of the datasheet mentions 256 bits = 32 bytes for the LUT
chapter 7 tells 30 bytes
according to section 6.8:
20 bytes waveform
10 bytes timing
1 byte named as VSH/VSL
1 empty byte
according to the command table, the lut has 240 bits (=30 bytes * 8 bits)
issue #347
2017-09-08 15:05:44 +08:00
LUT / Refresh time
total_refresh_time = (refresh_lines + dummy_lines*2)*TGate*TS_Sum/f_OSC
f_OSC=1MHz (according to the datasheets)
refreh_lines = 296 (for the waveshare display, 0x045 cmd)
dummy_lines = 22 (for the upcoming u8g2 code, 0x03a cmd)
TGate = 62 (POR default, 0x03b cmd)
TS_Sum: Sum of all TS entries of the second part of the LUT
f_OSC: 1MHz according to the datasheet.
so we have
total_refresh_time = 21080*TS_Sum/1000000 = 21ms * TS_Sum
This file includes two devices:
u8x8_d_il3820_296x128 --> includes LUT which is probably from the WaveShare 2.9 Vendor
u8x8_d_il3820_v2_296x128 --> includes LUT which was optimized for faster speed and lesser flicker
