Hello, I'm working with a PCB based on STM32L451VC MCU and I have different problems with the ADC. I'm trying to measure an input channel using the HALs provided by the STM32CubeMX but I can't achieve it. The main problem is that the bit ADRDY from A...
I read in section 6.2.1 of the STM32F479 reference manual that this Pin will Output a 20us reset pulse during Watchdog and other internal events. I did not find any Output characteristics for NRST and the statement in section 6.2.1 was stated almost...
Hi,I'm attempting to pass a parameter for a conditional compile from the gcc command line to my application. I have two build makefiles, one for debug and one for release. We have some code that's only meant for the release build. So far, so good. If...
STM32G070 is *NOT* supposed to have DAC, UCPD etc., at least not "officially"?!
Hey everyone,I'm still busy scoping out how to do this. I've been looking int methods to generate sine waves and so far it looks like some of the methods use lookup tables or trig functions from cmsis.Although I don't think this would be very ideal, ...
Dear Members,Is it fast enough to sample 115200 bps with 230400 ?Is it possible to get 230400 bps with 2.097MHz APB ? or I need more ?thanks
Hey guys,I have this project with STM32H743 MCUs one board uses ZI and second VI version. Sources for both boards were generated in CubeMX.After many unsuccessful attempts to get these two boards talking to each other via classic CAN I replaced one o...
Most 12bit ADCs of ST are specified not very accurate in DNL, INL, and total unadjusted Error. Especially DNL allows worst case scenarios of results being non-consecutive. I use these ADCs for several years now for slow signals and found ways in HW- ...
Hardware tested and functional.Commands modified on QSPI example (STM32Cube_FW-F7_V1.15.0) and the erase, read and write commands are functional.Problem to develop an externa loader, based on STM32F769I-EVAL example(using SW4 and MDK-ARM).The MDK_ARM...
