While the Coarse calibration in RTCv2 is obsolete, in 'L1 and 'F2 it's the only method (and I know 'L1 is NRND, but it's still around and will be for years to come, if ST sticks to its commitment), and as long as it's mentioned in 'F4 it should be pr...

Through the Characteristics chapter of L78XX DS, the page break is placed incorrectly so, that the conditions - and sometimes also the first row of the table itself - is at the preceding page. Yes, it's formally OK, but is this how ST intends to pres...

(Spotted by sx107.)I know the subject is not very descriptive, but a figure is worth 1000 words:It's also in other 'H7 RMs; I leave it to ST to check them all :)(Btw. this is a carryover from the 'F7 RM, where both OTG's SOF indeed feed into TIM2 ITR...

PHY is the clock source for both Rx and Tx in MII mode.So, you need the TX_CLK and RX_CLK outputs from PHY to be connected to ETH_TX_CLK and ETH_RX_CLK pins (marked in DS as ETH_MII_TX_CLK=PC3 and ETH_MII_RX_CLK=PA1) of the 'H5 respectively. These pi...

There is no native mechanism through which a trigger can be forced in a timer, so you have to generate a real trigger. One way to do this may be to switch TS to one of the ITRx (e.g. an unused timer) and generate trigger from there (e.g. by setting t...

> data is an array of chars, so I thouht that using it as an argument would automatically take a pointer to it Yes it would, would you use data as parameter. But you used *data, i.e. you dereferenced that pointer, i.e. you took the value of the first...
