   …should perhaps target the f407vet6 or zet6,zgt6 board directly rather than stick with stm32f103 (though it is a possibility as well). the main thing is that m4 (f407) has 2 fpu in the cores and that would significantly speed up path computations and of course …

2. Problems with regular simultaneous dual ADC conversion with DMA transfer

   …f all, let me share good news. I finally figured this out, thanks for your posts. the STM32F103 can actually perform “regular simultaneous dual conversion with DMA transfer”. It took quite a lot of time to figure out. Read on if you like a mystery novel… and l…

   Just in case this is handy, I found some code that we may be able to port to Maple to do the SD Card SDIO https://bitbucket.org/antlabs_dev/fatfs … 32f103/src But I better check it works first. One thing to note, the F103C series don’t have SDIO e.g. Maple Min…
