Hello,

my name is Roberto, i'm working on a single pixel camera. i have no much experice about stm32. I would use stm32f4's adc to read the value mesured by a photodiode (because it is 12 bit adc).

I'm writing a program in which i would read the measured photodiode voltage avery time i want in matlab. I would ask if some one have an idea how to make it!

thanks for your attention

Roberto

Hello Roberto,

I'm not sure to understand want you want to do.

Do you want to use STM32 to get ADC value that you post process with MATLAB (you need a link to get STM32 value from PC)

or you want to build STM32 application to process ADC value?

Regards

Pascal

Hello Pascal,

Thank you for the answer. I want to use STM32 to get ADC value that you post process with MATLAB. I would perform this program:

1 matlab elaborates one pattern that will send to display

2 matlab ask stm32 to read ADC value from sensor and store it in a vector

3 go to 1

It will be a loop in wich for every pattern i will acquire a measure, than i'll perform other calculation. The only function of stm32 is to read the Analogue signal. I can't use Arduino because of is 10 bit ADC. Could you have some idea? (in arduino seems to be very simple: load firmata host on arduino and than ask from matlab program to read value)
