a. There are lots of mcus series to choose from . but i don't get understanding why there are few nucleo boards available. like for f7 nucleo f767zi is available. while there is another series stm32f765b. Is it easy to port from one chip to another i...
I'm using the STM32F446VE with 3 ADCs. I have a 50 kHz PWM running and want 2 of the ADCs to measure 2 Channels synchronized with the 50 kHz PWM.To achive this I used the regular simultanuous dual mode, and triggered the master ADC with the Trigger 8...
Hi,I'm using a STM32F746G-DISCO and I write my own Graphic Lib.Now I want to put the bmp icons into the QSPI Flash.What I've done....Linker file is changed MEMORY { RAM (xrw) : ORIGIN = 0x20000000, LENGTH = 320K FLASH (rx) ...
Hi,I've been trying to get the SDMM1 working on a custom board with an eMMC (ISSI 32GB).Are there any working examples from ST that verifies you have actually tested the MMC side of the HAL library to be working? @Imen DAHMEN I am able to get the CS...
Thank you for helping.How do I back up the registers when the power is turned off without the VBAT pin?Thank you.
Hi,I wonder if the STM32H743 can sample and convert 1 ADC sample in 10 nanoseconds?According to the specs the ADC speed (sample + convert) at 14bit resolution with 50MHz ADC clock , one sample will take 200 nanoseconds.I have no problem lowering the ...

Table 226 on page 906 has an entry HRTIM_TIMxCMP1CR <- I don't think this is a real register.Section 27.3.8, page 888 second line in last paragraph says "any of the 5 timers". I think that should be 6 timers.Section 27.5.66, page 1050 says Bits 31:0 ...
