# eForth for STM32F407 Discovery board

## local studies by wa1tnr

`Target board:` **STM32F407 Discovery**

`Target board:` **Adafruit STM32F405 Express**

#### NEWS

##### TURNKEY with eForth logo in blue - working

As of 20 December, the turnkey code seems to be working

well - displays the eForth logo on the Lumex 96x8 RGB

display (it uses TTL serial to talk, and a Hayes-like

'AT' command set, similar (roughly) to an older modem.

##### STM32F407 Discovery - primary target

The STM32F407 Discovery was received in the post, from

DigiKey, earlier in the year, and became the primary

target for the program, as a result (needed to have

the extra GPIO pins not available on the Adafruit

target, which is otherwise suitable).

##### Lumex 96x8 RGB matrix, 3mm pitch, supported.

The Lumex display uses Hayes style 'AT' commands.

The trick to messaging to the display is to do so

continuously; if there's much of a delay, then the

display will not accumulate the message - it will

start over again at the left margin, after blanking

the entire display.

The Lumex display support was written entirely in Forth. ;)

Including the setup for the second USART pin pair.

    STM32 eForth - 2014

        http://forth.org/OffeteStore/2165_stm32eForth720.zip

Target board:  Adafruit STM32F405 Express

  http://adafru.it/4382

Dr. Ting's eForth runs (unmodified) on the Adafruit board.

GPIO support is on four unavailable pins, however.

TX/RX (for USART1) is brought out on (STM32F405 Express) SCL/SDA.
