Just a short video about the look of the new Solar BMS. There will soon be a Kickstarter for this new version (4 different variants) SBMS100 (120A overcurrent limit for both charging and discharging dual PV input) SBMS65 (80A overcurrent single PV input) SBMS40 (48A overcurrent dual PV input) SBMS25 (32A overcurrent single PV input) The 3D rendering was done in Blender 3D I will soon be able to give much more info. ... https://www.youtube.com/watch?v=lqDD0X5twFE

I show the small 64x48 graph that I want to use on the SBMS100 it will probably be 60x48 active resolution so that can display the last minute with 1 second resolution and the last hour with 1 minute resolution and a third one for last 12 or 18h did not decide as of now need to think about that. There will probably be multiple small graphs like this on one page (no problem since it takes just under 6ms to update one of them) and there will probably be a zoom function to display a larger graph if needed still need to think on how I implement all this. There will be 7 ADC inputs available one is differential that will be used to monitor the battery current (charge and discharge) then another two of the single ended will be used to monitor the PV1 and PV2 inputs and the other 4 of them will be available to user for automations measuring external loads or anything else you can think off. On the side that 8x is the PGA (programmable gain amplifier gain) it starts with that max 8x and will auto-range based on the input signal down to 0.5x I think auto ranging works correctly I will need to test more. ... https://www.youtube.com/watch?v=Zr0g_X7oKdE

SBMS100 / SBMS60 user interface. Here is the SBMS user manual http://electrodacus.com/SBMS100/manual/SBMSmanual.pdf You can check the google+ page for even more details and recurses https://plus.google.com/+electrodacus...

Just a short video with the latest library for the ILI9341 to be used on the SBMS100 project. As you seen in my last video this test was taking 84.326 seconds no DMA and no Optimization (I used Optimization None -O0) and if I add Optimization Level -O1 I can get the same library without DMA at 47.207 seconds (that is really great). Adding DMA without optimization -O0 gets the test done in 49.150 seconds while adding -O1 to the DMA version gets 33.712 as you see in this video. Compared to original library this is about 30x faster and now really as good as it can get at 40MHz CPU and 20MHz SPI. SPI is full there is nothing more to optimize at this point. ... https://www.youtube.com/watch?v=q50A47aAI9M
