Hi,big surprise: when activating SAI on H7A3ZIT , no configuration possible : ...nothing to configure...+ on IDE 1.18.0 , with newest Cube package: 1.12.1+ on H743ZIT , looks as it should:... V1.12.2 coming then ? - or "manual setting needed ? on H...
InSTGAP3SXSdatasheet is funny table , input -> output state, the most important thing for a driver - but wrong:btw : 1. Do not care. -- is perfect here.
Hi,i just tried to see the reaction on some events on a system with H7A3 cpu and was surprised:EXTI response time was 50 us ! This is a lot for a ARM cpu running at 200MHz - too much, i would say.ED: wrong timings measured, my error : pins have cer....
Hi,in ds for STM32H747xI/G , DS12930 Rev 2 , for Temp.sensor CAL2 : 130° (Parameter) is written here: BUT max. temp for chip is 125° :So i assume, this is misspelled , because in all other : (H743, H750, H7A3 ..) 110° + 30° are given.NOT 130° .
Try with setting: connect mode normal + software reset ; (nrst not needed)if V3miniE not finding target, you puzzled the swd/swc lines, or no contact on a line to target.Or (too) long wires to target - V3 is much more sensible for stray-in , no relia...
Hi,>When I set the gpio pins as OUTPUT and then I set them HIGH, is it correct that I expect to have 3.3V at the pin yes. >the timers could affect the behaviorIf you try to use the same pins for timer output, pwm or etc, - yes. One of them will "win"...
Hi,> Do you think I burnt something in the board? yes.check : when pressing reset button , is power consumption also very high ?yes: chip damaged.no: your program doing something strange; use CubeProgrammer and do full chip erase.->At the same time I...
Hi, @KDJEM.1 ,similar ...but new. Or new old recovered, because on last Cube 1.11.2 :it was ok, at least SAI :--- but SWV not working here at all !here sending on SWO in main loop - nothing comes to console, no profiling also:btw on H743ZIT its work...
>Need an MCU product with a built-in ADC sampling speed of about 20MspsThere is no internal 20 Msps ADC.ie H743 has 3 ADCs, each can :maybe possible: use all 3 ADCs in interleaved mode, so possible 21 Msps at 10 bit .But if you wanna make a DSO, need...
