UART to I2C master(s) converter, targetting to emulate SC18IM700(NXP) chip
UART to I2C master(s) converter, targetting to emulate SC18IM700(NXP) chip
Features
up to 4x I2C master
- for LPC824 implement, we can use up to 4 channels of I2C masters
- 1x Fm+ and 3x Fm I2C channels
- for LPC1768 implement, we can use up to 2 channels of I2C masters
- 2x Fm I2C channels
- for LPC11U35 implement, only one channel for I2C master,
but program uses USB CDC class for UART communication (means no external USB-Serial converter chip)
- 1x Fm+ I2C channels
1x SPI master
up to 2x 8bit GPIO
Tested Platforms
LPC824

LPC1768
LPC11U35
Quote:
LPC11U35 implement requires importing USBDevice library to use USBSerial class
