tjc02002 Posted February 27, 2018 Share Posted February 27, 2018 Ok so I see that the latest Pin2dmd solution uses an STM32F429 nucleo-144 development board. This board seems like it has capabilities that are unused by pin2dmd projects(lcd screen connector, Ethernet port) and it has an integral st-link. I’m wondering if there’s a simpler board(cheaper) that has the proper capability and also if a version exists without the st-link built in as the st link is only needed for initial programming and can be snapped off and reconnected via jumpers later if needed. I’m not super familiar with these micro controllers and capabilities/compatibility. Thoughts? Link to comment Share on other sites More sharing options...
Content Provider lucky1 Posted February 27, 2018 Content Provider Share Posted February 27, 2018 From the processor side a STM32F427VGT6 100LQFP would be enough. This board would also work with a suitable shield https://www.waveshare.com/core429i.htm Link to comment Share on other sites More sharing options...
tjc02002 Posted February 28, 2018 Author Share Posted February 28, 2018 Maybe I can ask this a different way. What are the options for boards that your shield is designed for. Is there just 1 single option? I see different stm32 nucleo144 boards. Link to comment Share on other sites More sharing options...
Content Provider lucky1 Posted February 28, 2018 Content Provider Share Posted February 28, 2018 Only the STM32F429 is sucessfully tested. Other F4 and L4 are to slow from the cpu clock side. F7 and H7 use a different architecture and are not code compatible due to the use of HAL instead of StandardPeripheral library. I have already started to port the code to HAL and the basic things are working on a H7 (display output, pinball input, sd card, usb etc) but still a long way to go and by far not prio 1 on my todo list.
