Include cleanup: drivers 2020-11-15 05:04:22 +01:00
JF f7e40b1b58 Re-implement sleep/wakeup for touch panel, display, NOR Flash, SPI and TWI. 2020-08-22 17:59:59 +02:00
JF 0b8e6c3fa2 Add SPI NOR Flash driver, WIP. 2020-05-07 19:53:51 +02:00
JF a91c68c931 Backup and restore vertical scroll offset when goind to sleep/wakeup to avoid scrambled display on wake-up. 2020-03-11 21:35:06 +01:00
JF 0a5cd60fe8 When a full screen refresh is done, apply a vertical scroll during the refresh. This makes the transition from one screen the another one smoother, even if the refresh rate is slow. 2020-03-08 21:46:25 +01:00
JF f30573a9b0 Add support for hardware assisted vertical scrolling. 2020-02-15 15:12:29 +01:00
JF 5fa4f5abe0 Better integration of SPI with DMA and IRQ. Using only 'End' IRQ. Perf could be improved by using 'Started' IRQ to prepare the next buffer while the current one is beeing sent. 2020-01-26 13:37:10 +01:00
JF eb7a1b3ac9 [WIP] Max SPI speed reached (119ms for a full refresh. Theo max : 240*240*16 = 115.2ms) using IRQ and DMA. 
Code needs some cleaning before integration.
