Hello!
I.m here with a question, if anyone can help me, even tho is not purely about Arduino, but close enough, on the SMT platform.
After i ordered a new board for my 3d printer, it came with a 3.5" TFT screen, using an STM32F207VCT6, which i'm not using, and i'm looking to use the chip and the screen to make another project.
I have an atmega328p board with some mosfets and temperature sensors that i want to use as my car chair heater control (i already have the system implemented, but using relays, and no temp control). (it gets quite toasty after a few minutes)
The idea is the following: I want to use the dedicated mosfet and atmega238p board to measure the temperatures, drive the mosfets, accept potentiometer input to control the temperature, and use the available SPI to send informations (measured temp, set temp, heater position off/backrest/ seat/backrest&seat) to the STM32F207CVT6 that will be used to display the informations.
The display i got is an CHUANGLI CL35BC106-40A (40 pin flex cable), which i don't seem to find any pinout on how to interface it with the SMT32F2 chip.. (the TFT is directly driven by the STM), here's a link with the TFT screen, but i'm not sure which variant it is...
I'm also thinking of using some of the remaining pins of the STM chip to make an mp3 player, reading songs from an USB drive, and display it on the same TFT using an empty button from my navigation system, to toggle between the heater and the mp3 player.
The biggest problem at this point, is that i have no idea how to interface the screen and the mcu(what library to use and what pinout to use), and the second problem is that i don't have a clue on how to interface the atmega and stm using the SPI communication.
If anyone can give me a hint on how to proceed, that'd be much apreciated
Thanks in advance!
