Final project will show a couple of temperature/humidity on each screen.
( I have 4 little ESP8266 with DHT12 and an Openhab server ).
First attempt with python and SPI ( hard and bitbanging ) is not working, I do not know why....
Second attempt with python and direct gpio access were working but very very very slow !
Final attempt coding in C and direct memory access for gpio works but it takes me times to search and find all these informations. ( example is working for gpio number < 32, other gpio have another base address ).
So I think this example can perhaps be helpful for someone and can save some times !
Samsung says it is mass producing a solid state drive with monstrous capacity. The "PM1643," as it is called, offers an insane 30.72TB of storage space! This is achieved by using 32 x 1TB NAND flash. "Samsung reached the new capacity and performance enhancements through several technology progressions in the design of its controller, DRAM packaging and associated software. Included in these advancements is a highly efficient controller architecture that integrates nine controllers from the previous high-capacity SSD lineup into a single package, enabling a greater amount of space within the SSD to be used for storage. The PM1643 drive also applies Through Silicon Via (TSV) technology to interconnect 8Gb DDR4 chips, creating 10 4GB TSV DRAM packages, totaling 40GB of DRAM. This marks the first time that TSV-applied DRAM has been used in an SSD," says Samsung.
He he, imagine an O2+ with 32 x 1TB NAND flash chips connected. :-)
