A development board for Lua programming

Posted on Thursday, January 2nd, 2014 in dev boards by DP


doub has been working on a development board for Lua programming:

So this project is about packing a relatively fast microcontroller, but not complex enough to require a high level OS (like Linux for SoC-class chips), with a big RAM chip. I picked a STM32F427, because I have some experience with the STM32 family, the core is a Cortex-M4F (floating point will help running Lua), and it is one of the few Cortex-M microcontrollers with an SDRAM controller. SDRAM is desirable over SRAM because it’s much more dense and there are 256Mbits (32Mbytes) chips available for a few dollars.

Via the forum.

    Nice board. I have been looking around for something very similar. Precision analog measurements however will, require separate analog and digital power supplies and well separated grounds. In high speed data acquisition, writing on SD cards could easily produce spikes in ADC measurements in spite of ferrite beads, inductors and RC filters used in supply lines to reduce these problems.

    Lua sucks gross, everyone does Python nowadays:
