Disclaimer: I don't normally use HAL, but I was trying to learn more about USB hosting so I decided to try out the demonstration application STM32Cube_FW_H7_V1.12.0 STM32H743I-EVAL USB_Host/CDC_StandaloneAs I don't have that board, I tried to hook up...

I have been using microSD chips reliably for many years with stm32f4, stm32h7 and stm32l4.But for one of my products, where space is at a premium, I am trying to use a SD-NAND chip XTSD04G, and I am running into occasional errors where an SDIO R1 com...

Does anyone have any experience of trying to control non-exisistant pins?I have a design that takes stm32f767 in the lqfp100 package. But none seem to be available.Looking around, I managed to procure a small run of stm32f779* in the wlcsp180 package...

I have a stm32f427 with 1Mx16 external SRAM and SDMMC.I am reading the SDMMC by DMA into the SRAM in two blocks of 512 bytes into a 1024 byte buffer.The SRAM is mapped from 0x64000000 - 0x641fffff. Address and data are not multiplexedI have now disco...

I am looking into the possibility of using a stm32 microcontroller (probably stm32f030) to directly* control the power transistors in a switch-mode power supply, in order to generate a high-power waveform.My current thinking has a PMOS switch transis...

Hi @Saket_Om ,So what you're telling me is that it is OK for the HAL to give wrong results for situations that have not been set up by HAL.That's a valid position. But it is disappointing. Particularly as USE_FULL_ASSERT is OFF by default.You could m...

Hi @TDK I have looked at the diff of that "fix", and although it might give better results for PClock1, it gets results wrong for HClock.The main change is to D1CorePrescTable which becomes (changes in bold)const uint8_t D1CorePrescTable[16] = {0, 0,...

For anyone to be able to answer that question correctly, we would need to know how you intend to use the pin PC13, and possibly the timing requirements for the "serial clock and data signals".Will PC13 only drive the /OE pin on the level-translator? ...

As I understand things, WolfSSL has a more restrictive license, in that your final product must be open-source OR you pay their license fee (not cheap).Depending whether you’re a hobbyist (OK with open-source), small business (might have difficulty j...

Hi @gbm hope you don't mind me disagreeing with my understanding of what you wrote. I could have misunderstood what you wrote in which case please correct me."No need for cathode transistors" - What current do you expect to flow through the LEDs? I'v...
