VLF/LF Receiver implemented in microprocessor - Hardware Configuration (Part 3 of n)
This post assumes that the RF pre-amp and audio out circuits have been built as described by I2PHD in his original paper found under the ARM Radio section of his website.
Microprocessor - STM32F746-Nucleo board.
LCD - ILI9341 driver, looks the same as this one
Rotary encoder with integrated push switch
My code uses the following pin connections:
Component Pin STM32F746 Pin
Rotary encoder clockwise PB4
Rotary encoder anti-clockwise PB5
Rotary encoder centre GND
Rotary encoder push button PA0
RF In PA3
Audio Out PA4
In the next post I will describe the code I have added to support the rotary encoder functionality as well as the changes to the screen layout.
