Internal file storage is now working for F7. The flash is laid out a bit differently to the F4 - 4 x 32K, 1 x 128K with the rest 256K, so the internal storage is 96K. Added more pind definitions for STM32F7DISC board. Made USART1 be the default HWUART repl. The STLINK usb connector also looks like a USB serial port which is attached to USART1 on the STM32F7DISC. 2015-07-29T23:38:32+00:00 Dave Hylands dhylands@gmail.com 2015-07-28T18:13:33+00:00 urn:sha1:92d4b51ad5d828930334f87d9619a78b5877a384 2015-07-29T23:38:25+00:00 Dave Hylands dhylands@gmail.com 2015-07-28T15:36:26+00:00 urn:sha1:ea8bf8105812b36fbf1596a78c6e14aa0a0c5a36 2015-04-18T20:40:59+00:00 Damien George damien.p.george@gmail.com 2015-04-18T15:27:53+00:00 urn:sha1:6be0bbb886de613adfbd3b653e44e25fbb3569c5 It uses a 16k cache buffer and so the filesystem size is limited. 2014-05-03T22:27:38+00:00 Damien George damien.p.george@gmail.com 2014-05-03T22:27:38+00:00 urn:sha1:04b9147e150d2d6fa3750f312fe328b6a71c1b28 Blanket wide to all .c and .h files. Some files originating from ST are difficult to deal with (license wise) so it was left out of those. Also merged modpyb.h, modos.h, modstm.h and modtime.h in stmhal/. 2014-04-16T22:08:36+00:00 Damien George damien.p.george@gmail.com 2014-04-16T22:08:36+00:00 urn:sha1:6d983539bcff2a540dd136a7e84e1db2b334528f Internal flash used for the filesystem is now written (from the cache) only after a 5s delay, or when a file is closed, or when the drive is unmounted from the host. This delay means that multiple writes can accumulate in the cache, and leads to less writes to the flash, making it last longer. It's implemented by a high-priority interrupt that takes care of flash erase and write, and flushing the cache. This is still only an interim solution for the flash filesystem. It eventually needs to be replaced with something that uses less RAM for the cache, something that can use more of the flash, and something that does proper wear levelling. 2014-03-17T13:31:35+00:00 Damien George damien.p.george@gmail.com 2014-03-17T13:31:35+00:00 urn:sha1:9e5ea4d768da3273b6d060cceffcc858e1c4827d
