Low priority - code works OK for I2C_1 on PB8/9 only.
I2C_2/I2C_3 not accessible via wire.

I2C init data is hardwired into twi.c (see twi.c : 148)
->No matter what the options are set in PeripheralPins.h, the code will initialise to SCL/SDA on PB8/9

Wire.cpp only allows I2C1 (see wire.cpp : 300)
-> only one I2C is instanced in twi.h (@ line 54)

Code needs rewriting to use PeripheralPins structures to update the g_i2c_init_info[NB_I2C_INSTANCES] data before i2c_custom_init() is called from wire.cpp:61

Frederic,

I've been testing the advanced ADC\DAC modes (beyond single conversion, polling) using the templates from STM32Cube_FW_F4_V1.15.0\Projects\STM324x9I_EVAL\Examples\ADC\ and \DAC\

When using these other analog routines, HAL_ADC_MspInit() etc need to be customised for each configuration.

Now I'm trying out the dual-interleaved mode, it has become clear that the code in analog.c is just an initial test.

As HAL_ADC_MspInit() needs to be customised for each configuration, I'm looking at hiding the MSP_Init functions in analog.c at the system level and moving the code up to a library. The Init functions can then be customised for each mode.

When I tried this, other functions break - like dac_stop() and pwm_stop(). I think I'll be able to leave them in analog.c

Give me a few days and I'll have something workable.

Single-Polling and Single-interrupt are working already, using pretty much standard code from the Cube libraries, next up is dual-interleaved

SCLK is defined in variant.h and named also a parameter in the lib:
local/data/work/stm32/stm32duino/arduino-1.8.1/hardware/STM/stm32f4/libraries/TFT/src/utility/Adafruit_ST7735.h:101:64: note: in expansion of macro 'SCLK'
Adafruit_ST7735(uint8_t CS, uint8_t RS, uint8_t SID, uint8_t SCLK,

Pulse range is not good => 254 - 850us. Should be 500 - 1700us.
