Fix IAR serial fgets fgetc
Taken from PR #770:
setbuf(_file, NULL), and std::setvbuf(_file,NULL,_IONBF,NULL) should both give an unbuffered stream (the data is directly written to the input buffer). IAR sets a buffer anyway of size 512 bytes for these calls. Calling setvbuff(_file,buf,_IONBF,NULL) with a buffer that is not a NULL pointer sets the buffer to size one. Which means that as soon as a char is read it is written to the real buffer. If people are interested in looking at this further they can look at the files under ARM/src/dlib: fgets.c, fflush.c, xfrpep.c and xfwprep.c
Three changes, first it fixes:
https://github.com/mbedmicro/mbed/issues/761 (which was reported
slightly wrong because K20 has again different clocking from KLXX for
uarts).
Second it adds mcgpllfll to clk_freqs, which again is different for K20
compared to KLXX .
Finally it adds the fractional baudrate divider for more accurate serial
baudrates.
Change I2C driver transfer sequence to go according to H/W manual.
Changed contents are as below.
- Access procedure of ACTBT bit of MR3 register
- Issuance procedure of stop condition
When read the timer value, it have a potential to read abnormal value.
Because we used 16bit + 16bit cascade timer and read timer count separately.
Changed usticker timer from 16bit + 16bit cascade timer to 32bit timer to fix the bug.
Updates startup files to actual versions of STM32 Cube drivers without
any changes of STs drivers:
- DISCO_F303VC
- DISCO_F334
- NUCLEO_F030
- NUCLEO_F072
- NUCLEO_F302
- NUCLEO_F334
- CoIDE options: wrap main and linker option DiscradUnusedSection=1 was
missing in some targets
- CoIDE options: corrected flash loader config for Nucleo_F030 and
Nucleo_F072
- CoIDE options: corrected memory layout (not used per default but now
it is the same as in linker script)
- gcc linker script: changed the memory size from hex number e.g. 0x2000
to decimal 8K
The bugs of IRQ Edge Interrupt as below.
- Not call a function that was registered in rise, always call a function that was registered in the fall.
- If there are multiple interrupt sources, there is a possibility that end the wrong interrupt processing.
