OLED on LPC922

[pete68]

Hello
can anyone tell me if there is a library to drive an I2C OLED display (Driver IC: SSD1306) with a 89LPC922?

thank you

i think: no.
furtermore: It's better to take the LPC1115!

[pete68]

it's fine even in 1115,
my goal is to read a temperature from the bus and display it on the display, that's all.

For the 1115 exists some driver code that can display text on a EA-DOGS display.
I think it's the EA-DOGS 102 that I used for implementation.

Showing other stuff should be possible, but it most probably needs some
implementation, which should not be too hard as the protocol is quite straight
forward.

thanks, if i solve, i will leave some information for those who need it.

it seems that the library for ARM U8G can work, but implementing a project in LPCxpresso is not easy for those who are not used to writing in C.

Every help is welcome

thank you

I gave up (for now) to directly control the SSD1306 display with LPC1115 and I'm using a 89LPC922 with RS232 firmware that transforms the received telegrams from the bus into an information to be sent as text to an arduino (with which it is easy to control a oled with the u8g library and the like). It works, however I have difficulty in transforming DPT9 messages into decimal values ​​to be sent to arduino. Is there any routine to use in these cases?

thank you
