# Application components for STMicro STM32 MCUs
Toolchain: Migrating from TrueSTUDIO+CubeMX to [STM32CubeIDE](https://www.st.com/en/development-tools/stm32cubeide.html)
## Common libraries
### [NUCLEO-F401RE](http://www.st.com/en/evaluation-tools/nucleo-f401re.html) board
- [DCT Type-II implementation on CMSIS-DSP (also works on L4)](./NUCLEO-F401RE/DCT) including a zigzag scan utility function.
## Application components
### [NUCLEO-F401RE](http://www.st.com/en/evaluation-tools/nucleo-f401re.html) board
- [Thermography (infrared array sensor) and rock-paper-scissors recogniton with Keras/TensorFlow](./NUCLEO-F401RE/Thermography)
- [X-CUBE-AI (ML inference on MCU with 2D images from an infrared array sensor)](./NUCLEO-F401RE/AI)
- [X-CUBE-BLE1 (BLE)](./NUCLEO-F401RE/BLE)
### [NUCLEO-L476RG](http://www.st.com/en/evaluation-tools/nucleo-l476rg.html) board
- [HelloWorld](./NUCLEO-L476RG/HelloWorld)
- [GPIO_Interrupt](./NUCLEO-L476RG/GPIO_Interrupt)

- [DAC with triangular wave and sine wave](./NUCLEO-L476RG/DAC/README.md)
- [Mic->ADC->DAC pipeline](./NUCLEO-L476RG/Mic_ADC_DAC/README.md)
- [Sound Effector](./NUCLEO-L476RG/Sound_Effector)
- [Chirp compression](./NUCLEO-L476RG/Chirp_Compression)
### [NUCLEO-F401RE](http://www.st.com/en/evaluation-tools/nucleo-f401re.html) and [NUCLEO-L476RG](http://www.st.com/en/evaluation-tools/nucleo-l476rg.html) boards
#### Dynamic NFC tags
- [ST25DV04K (NFC) on F401RE](./NUCLEO-F401RE/NFC)
- [ST25DV04K (NFC) on L476RG](./NUCLEO-L476RG/NFC)
### [STM32F4 Discovery](http://www.st.com/en/evaluation-tools/stm32f4discovery.html) board
- [Camera (CMOS image sensor OV7670)](./STM32F4-Discovery/Camera)
- [BlueSwitch](./STM32F4-Discovery/BlueSwitch)
- [HelloWorld](./STM32F4-Discovery/HelloWorld)
- [LED_blinking](./STM32F4-Discovery/LED_blinking)
- [PWM-output](./STM32F4-Discovery/PWM-output)
- [AudioWeaver](./STM32F4-Discovery/AudioWeaver)
#### printf issue
I managed to support printf on USART2.
Physical configuration:
```
STM32F407
+------------+
X 5V |
GND ----- GND FTDI |
PA3(RX) ----- TX USB-UART ===== USB ======> PC
PA2(TX) ----- RX converter |
+------------+
```
Include the following snippet in main.c to support printf:
```
int _write(int file, char *pbuf, int len)
{
HAL_UART_Transmit(&huart2, (uint8_t *)pbuf, len, 1000);
return len;
}
```
#### PWM test
PWM output (100Hz, 50% duty) to PA8:
