Getting Started with CEM102 EVB Tutorial

Getting Started with CEM102 EVB

Required Hardware

• CEM102 Evaluation Board (EVB)
• J-Link debugger
• USB cable
• Power supply (optional)

Required Software

• OnSemi IDE (Integrated Development Environment)
• TerraTerm software for monitoring current values

Setting up the Board

1. Connect the J-Link debugger to the board using a USB cable.
2. If required, connect an external power supply to the board.
3. Ensure that the board is properly seated and all connections are secure.

Importing and Building Projects in OnSemi IDE

1. Create a new project in the OnSemi IDE.
2. Select the CEM102 EVB as the target device.
3. Import the required libraries and source files.
4. Build the project using the OnSemi IDE's build tools.

Debugging Applications

1. Create a new debug configuration in the OnSemi IDE.
2. Select the J-Link debugger as the target interface.
3. Set up the debug settings and options according to your requirements.
4. Start the debugging process using the OnSemi IDE's debug tools.

Monitoring Current Values Using TerraTerm Software

1. Open the TerraTerm application and select the serial port to use.
2. Set up the communication settings according to your requirements.
3. Start monitoring the current values at the WE1 channel.
4. Calibrate the measurements as required.

Measuring Current Values

1. Insert a resistor between the WE1 pin and ground.
2. Measure the voltage value at the WE1 pin using the TerraTerm software.
3. Calculate the theoretical current value using the measured resistance and voltage values.
4. Compare the calculated value with the actual measurement to ensure accuracy.

• TMS320LF2407A DSP processor
• 128 KB of onboard flash memory
• 16 KB of SRAM
• McASP (Multichannel Audio Serial Port)
• I2C, SPI, and UART interfaces

#include "cem102.h"
int main(void) {
  // Initialize the GPIO pin
  cem102_gpio_init();
  
  while (1) {
    // Toggle the LED on and off
    cem102_gpio_toggle(LED_PIN);
    // Delay for a short period of time
    delay_ms(500);
  }
}

• CEM102 EVB (Evaluation Board)
• Power Supply (5V, 2A)
• USB Cable (Micro-USB to USB-A)
• Computer with Windows, macOS, or Linux

• CEM102 EVB Software (available on the manufacturer's website)
• Serial Terminal Emulator (e.g. PuTTY, CoolTerm, or Screen)
• Text Editor or IDE (optional)

1. Connect the power supply to the CEM102 EVB.
2. Connect the USB cable to the CEM102 EVB and the computer.
3. Install the CEM102 EVB Software on the computer if not already installed.
4. Launch the Serial Terminal Emulator and configure it to connect to the CEM102 EVB's serial interface (typically at 115200 baud, 8N1).

1. The CEM102 EVB will automatically boot into the bootloader when powered on.
2. The bootloader will wait for a short period (typically 5 seconds) for a user to press the 'c' key to enter the command mode.
3. If the 'c' key is not pressed, the bootloader will load the default firmware image from flash memory and start executing it.

• In command mode, users can interact with the CEM102 EVB using a set of predefined commands (e.g. 'help', 'info', 'flash', etc.).
• Users can also use this mode to update the firmware image or load custom applications.

1. To update the firmware, users need to enter the 'flash' command in the command mode.
2. The bootloader will then prompt the user to select the firmware image file and confirm the update process.
3. Once confirmed, the bootloader will erase the existing firmware image and program the new one into flash memory.
