JF 2f710d06f3 Workaround for bug https://github.com/JF002/Pinetime/issues/79 until a better fix is found. 
When the driver is stuck in an infinite loop for more than ~2.5ms, the TWI device is re-init and the transaction is retried.

Read() and Write() return an error code.

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.
