LPC1788FBD208 data logger

[aut]

I'm using the LPC1788 (exactly LPC1788FBD208) microcontroller to make a data logger system. Several analog signals are connected to LPC1788. The user can download the acquired data, by means of several ways:

1) Via GPRS (a GPRS module is connected to the USART0 serial port)
2) Via Ethernet (the remote control room reads the data using internet connection)
3) Via USB pendrive (when the USB pendrive is plugged, the LPC1788 automatically download in the pendrive the data)
4) Connecting the LPC1788 to a PC (laptop or other type of personal computer) via USB cable (in this case, the LPC1788 has to be seen as an external hard disk)

Could you tell me in your opinion if a similar system can work properly?

Thanks

Hi Nico,

I'm not sure I understand your question, have you already implemented this functionality? Are you looking for recommendations on how to achieve this? If you are looking for example projects for UART, Ethernet and USB host and Device I would recommend you to take a look to the LPCOpen package for the LPC1788 devices:

Hope it helps!

Hi Carlos,

thanks for your support.

I have not implemented yet the functionality described in my previous post. I want to know if the hardware features of LPC1788FBD208 device allow to make these functionality.

Hi Nico,

Yes, the hardware features support the interfaces you are looking for. Regarding the memory, I have done a quick evaluation and it should be able to fit you application. The application sizes in dec are:

Data logger - periph_sdmmc 42580

Uart - periph_uart_rb 10668

Ethernet - lwip_tcpecho_sa 64636

USB Host - lpcusblib_MassStorageHost 59176

USB Device - usbd_lib_composite 16932

Hope it helps!
