LPC804 I2C Example

richardsoennich — Thu, 13 Jun 2019 18:07:01 GMT

I have the drivers from the latest SDK, fsl_i2c.c etc.

Besides the drivers themselves are there any example projects? I am looking for I2C in particular.

I am nervous about designing in this device as it seems to come from Freescale and I don't see much support.

Thanks

Rich

Hi Richard Soennichsen

Here is an application note AN12125_Using_LPC802_as_I2C-bus_EEPROM

https://www.nxp.com/docs/en/application-note/AN12125_LPC802.zip

Hope this can help you.

Have a great day,
Jun Zhang

Thanks for the help. I am not finding that example as it is more about the uC emulating an eeprom than standard I2C. Is there a simple I2C master example?

Thanks

Rich

The LPC80x are an ARM Cortex-M0+ based, low-cost 32-bit MCU family operating at CPU frequencies of up to 15 MHz. The LPC804 support up to 32 KB of flash memory and 4 KB of SRAM. The peripheral complement of the LPC80x includes a CRC engine, two I2C-bus interfaces, two USARTs, one SPI interface, Capacitive Touch Interface (Cap Touch), one multi-rate timer, self-wake-up timer, one general purpose 32-bit counter/timer, one 12-bit ADC, one10-bit DAC, one analog comparator www.tellthebell.com function-configurable I/O ports through a switch matrix, an input pattern match engine, Programmable Logic Unit (PLU), and up to 30 general-purpose I/O pins.

Jun,

Thank you for the code bundle. I am porting it to IAR now. I have given up on the port Freescale libraries.
