SSD1606: 128x180x2 |
|
two-bit, four graylevels |
|
command |
|
0x22: assign actions |
|
0x20: execute actions |
|
|
|
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 |
|
|
|
Disable Charge Pump and Clock require about 267ms |
|
Enable Charge Pump and Clock require about 10ms |
|
|
|
Notes: |
|
- Introduced a refresh display message, which copies RAM to display |
|
- Charge pump and clock are only enabled for the transfer RAM to display |
|
- U8x8 will not really work because of the two buffers in the SSD1606, however U8g2 should be ok. |
