Some I2C devices require specific zero length read/write sequences which
the HAL_I2C_IsDeviceReady() redirect interferes with. After Removing
these redirects, it was confirmed that zero length reads and writes
would both still work correctly for detecting presence/absence of an
I2C device on a bus.
In case we've run through the entire GPIOs loop, withouth finding a
matching interrupt, we're in the case of a spurious interrupt, let's
raise an error to track it down.
When disabling GPIO irq, also the falling / rising edge settings need
to be reset (EXTI_RTSR and EXTI_FTSR registers).
If not reset, the same EXTI line can be later enabled again with a wrong
Rising / Falling configuration. This was especially seen and reported in
ci-test tests-api-interruptin on NUCLEO_F446RE target where DIO2=PA_10 and
DIO6=PB_10 were successively tested: as they are sharing the same EXTI_LINE
(EXTI_10), this resulted in calling the irq_handler with wrong
IRQ_FALL/IRQ_RAISE parameter and donothing being called in loop.
This commit completely rewrote flash_api.c in a few places so kicked out changes from Master and accepted the branch changes.
F429 + F439 : changes after code review
GetSector has been rewritten
- default value is the same as before patch
- system_stm32f4xx.c file is copied to family level with all other ST cube files
- specific clock configuration is now in a new file: system_clock.c
- nvic_addr.h file is now in TARGET_STM level, and can be used everywhere
With default sampling time, the MBED2 and CI test shield tests would fail
because the stabilization slope of ADC is relatively slow.
ERROR (out:0.8000) - (in:0.7407) = (0.0593)
ERROR (out:0.9000) - (in:0.8354) = (0.0646)
ERROR (out:1.0000) - (in:0.9289) = (0.0711)
This is related to the 10kOhms resistors used to connect Ain to
Aout mounted on the CI shileds, and internal capacitance of L0 targets.
If connecting Ain and Aout with wires, bypassing the resistors, the test
is passed. So we're increasing the sampling time to let the automated
ci shiled tests PASS.
OK (out:0.8000) - (in:0.7863) = (0.0137)
OK (out:0.9000) - (in:0.8869) = (0.0131)
OK (out:1.0000) - (in:0.9844) = (0.0156)
Moving some code in common to be able to manage several ADC instances,
or several channels of an instance.
The change involves:
- moving dac_s structure definition to common_object.h
- create TARGET_STM/analogout_api.c and move fully common analog_out
functions in there
- rename analogout_api.c of each target family into analogout_device.c
to keep platform specific code
- update analogout_device.c to rely on obj->handle and obj->channel
- align analogout_init function as much as possible between families in
analogout_device.c files
ADC1 channel2 and ADC2 of few targets only have an output switch and no
buffer. This switch needs to be enabled, and also the buffer can be enabled
in order to reduce the output impedance on output, and to drive external
loads directly without having to add an external operational amplifier.
This allows a proper handling of multiple instances. Also this commit
stores the channel in the HAL format so that it can be re-used more easily
and call to HAL are straightforward.
This commit implements a SPI mode which will offer better performance
thanks to usage of Lower Layer API which use fewer registers access,
at the cost of lower robustness (no error management).
Following
Merge pull request #4063 from LMESTM/17q2_L4_bootloader
the NUCLEO_L476RG binairies could not boot anymore.
The change done in #4063 was derived from work on NUCLEO_L429ZI target
which supports uvisor. The VECTORS defintiion is introduced as part of
uvisor support and requires further changes in ld file which were missing.
As uvisor is not considered yet, we remove VECTORS for now and will
introduce only when needed.
Remove HAL_Init and related code from SystemInit and move it to
mbed_sdk_init. The function SystemInit is called early in the boot
sequence before RAM is initialized or the VTOR is setup, so it should
not be used to perform the HAL initialization.
This fixes crashes due the vector table being used before it has been
relocated.
