TLE94112

This module is used to initialize and setup an Infineon TLE94112. For testing I used a NUCLEO-STM32F401 + Infineon Shield with the TLE94112 (About Modules) module.

Required Resources

This module require the following resources:

• SPI Interface
• Chip select pin
• Chip Enable pin

How to use my module

A5, A6 and A7 are the SPI Interface (SPI1), B6 is the chip select and A9 Chip enable.

SPI1.setup({sck:A5, miso:A6, mosi:A7, baud:1000000, mode:1, order:'lsb' });
var TLE = require("TLE94112").connect(SPI1, B6, A9);
TLE.enable();
TLE.setPWMSource(1,1);
TLE.setPWMFrequency(1,3);
TLE.setDutyCycle(1, 240 ); // Set duty cycle of PWM channel to 90 %
TLE.setDirection(1,1);

Display device status

TLE.logCtrlReg();
TLE.logSysDiag();

Shutdown

This will stop the complete chip. Enter this also on command line to stop during testing.

TLE.disable();
