In one of our products, we create the control app in Python, but then need to control physical outputs/inputs of analog and digital nature. We need to use a microcontroller board for this. The microcontroller still needs lot of software, an RTOS, and number of tasks (serial, ADC, PWM etc etc). All this software needs to be written in the preferred dialect of C and using the preferred compiler of the vendor (MPLAB for Microchip's PIC controllers etc). It would be great if we could simply write in Python and then have this converted to the preferred microcontroller's assembly either as direct binary files or creating a C file with the assembly code inside asm() calls and then passing this C file to the MPLAB compiler. Life can go on even without this hack...but this hack would make life easier and more productive. > > > > > CorePy did it but not for microcontrollers > > P14p (or PyMite) actually creates a python interpreter in C and puts it > > inside the microcontroller, and its GPL. > > PyPy as you know is not yet for microcontrollers and only creates > assembly > > when the JIT kicks in. > > Cython/Pyrex would convert python with type specifications into extension > > module...but it will not fit into microcontrollers. > > > > I am looking for something more "simple", i.e. instead of writing C and > > compiling it to machine instructions...write python (restricted set..may > > be) and convert it to machine instructions. > > > > Any pointers will be of big help.. > > > > I see some projects like pyastra (circa 2006) and pyasm on Google but > nothing > which is maintained and has kept up. > > >> PyAstra is not maintained and in its current form only caters to the lower end of the PIC spectrum (PIC12, PIC16 i.e. 8 bit ones). What we would be using is PIC24 or dsPIC33 (16 bit processors with "lots"of RAM...30K RAM and 256K ROM :D) . > > > > > > Thanks and best regards, > > Vishal Sapre > > _______________________________________________ > > BangPypers mailing list > > BangPypers@python.org > > http://mail.python.org/mailman/listinfo/bangpypers > > > > > > -- > Regards, > > --Anand > _______________________________________________ > BangPypers mailing list > BangPypers@python.org > http://mail.python.org/mailman/listinfo/bangpypers > -- Thanks and best regards, Vishal Sapre --- "Life is 10% how you make it, and 90% how you take it" "बहुजन हिताय, बहुजन सुखाय (Benefit for most people, Happiness for most people.)" --- Please DONT print this email, unless you really need to.
