is there any micropython-powered board, which expose dedicated SPI, I2C, RGB and FSMC interface as female header just like two stm32 boards do
the long story
I am a newbie.
Currently, I try to learn how to make modules( sorry, English is not my mother language. I don't know whether it is proper to call a sensor/display/and_so_on as a module) work from software side.
However, since I carry out my study on breadboard with Dupont lines, failures appear frequently due to
- wrong wiring
- loose wiring
- mis-used pin, for example, a In-Pin is connected as an Out-pin
- the reason that some modules are second-hand, for example, Nokia 5110 display. I can't ensure they can work or not
Every time the module does not work, I have to check and re-wire it from time to time, which not only makes me tired(since small pin span) but also feel frustrated.
There are two stm32 boards which can be used to test most of the display of SPI/RGB/FSMC interface quickly. The 2 boards are programmed in C/C++, so we have to write different code for different display and then upload the compiled code into the board.
As we know, SPI and I2C are common used for modules( even some display uses SPI). For advanced display, RGB or FSMC interface are used. It seems that SPI/I2C/RGB/FSMC covers most of the common modules' interface(correct me if I am wrong).
So my question is
1. is there any micropython-powered board, which expose dedicated SPI, I2C, RGB and FSMC interface as female header just like two stm32 boards do
2. so the pins used for SPI, I2C, RGB and FSMC are always fixed, as a result the user can always use a code template without worry about wrong wiring, wrong pins
3. the board can supply a minimal code to judge whether a module can work or is bad
4. even more, the program can supply multi-function. I mean the user can choose to perform test on which kind of interface
