Posted on January 03, 2017 at 02:40Hi Imen,Thanks for the responses to each of my points!On 1, I had not seen this 4/3 SDIO_CK/fPCLK2 ratio, I had only noticed the second 3*width / 32 one. I had been using 4 bit SDIO, should have mentioned that, and...
Posted on December 30, 2016 at 19:49Hi,I spent ALOT of time getting these working as well. The SD drivers have many bugs/timing issues in them.For MSD and FatFS the most important issues to address are:1) PCLK2 to SDMMC_CK must be such that PCLK2 is...
Posted on December 11, 2016 at 03:23Hi Aaron,Use of 2 calibration points is actually very standard for linear temperature sensors, and by ST providing them for an inexpensive sensor in a processor like this is I believe somewhat unique. The first po...
Posted on December 10, 2016 at 20:00One more point on this, with respect to Vrefint calibrations you were using. Since they are also taken (e.g. for your F437 board) at a specific Vdda, they also need to be adjusted to properly compensate for the ac...
Posted on December 10, 2016 at 18:37 , ,Hi Sebastien,Thanks for the pseudocode!. Also have an F4 board and wasn't aware that it also had the 2 point temp sensor calibration values. ,Ours uses the F407, and just checked the data sheet and yes it also...
