I am using the arm m7, however I would like to use a cheaper processor to realize the following structure:
1- i2c output for OLED communication
2- two usart ports one for gps communication and one for gprs
3- a Gpio for communication with sensor.
I am in doubt between the m0 +, m23, m3. However if you have any other suggestions I would be grateful.
What is "cheap"? Why don't you try just the next smaller family? Since "arm m7" is a) wrong and b) imprecise it is hard to reply sufficiently accurate.
I am using a mcu in which it has several outputs, features and I do not need all of them, there are many for the project.
so i would like to know one that has less "resources" but that fits the program requirements mentioned above.
See my answer and use you favorite search engine or the one on the manufactures side.
Again, "cheap" is not precise. Neither is the rest you tell.BTW: Do not use "Insert Code" for normal text.
