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...
I am in the process of porting some code from stm32F405 to stm32L496 in the hope of reducing current consumption.One of the things my code does is write to an SD card, and because it writes a lot of data, I useSD_CMD_WRITE_MULT_BLOCKAnd then repeat {...
