Resolved! Issue with receiving sd card status at card init [SOLVED]
Hello *,I'm currently trying to use a micro-sd card breakout board on my Nucleo-H743ZI to store some data using the SDMMC interface and the FatFS middleware v0.12c (The breakout board is just here for the pull-up resistors on the lines).I've setup th...
STM32 Alexa Voice Services Solution
I am interested in developing Alexa built-in device using your solution mentioned in the Link.But this link also mentioned that "Amazon decided to maintain AVS for IoT system for existing products only. This solution can’t be used to develop a new pr...
Can the definition of a HAL_ADC_ConvCpltCallback interfere with the DAC/DMA?
I am experimenting with an STM32F3348-DISO board. A waveform is generated using the timer TIM6 update event and DMA channel 3 (cyclic mode). At the same time, I am using an ADC to read the same waveform into a dedicated buffer (DMA channel 1), and th...
Not able to mount SD card with SDMMC 4-bit bus, but with 1 bit but it works fine
Board = NUCLEO-F756ZGSD Card Spec = SDHC Class 10Board to SD card connection wire length = ~10cmSDMMCCLK clock divide factor = 8 (So SDMMC_CK = 3 MHz)Accept CLK line, on all lines 22K pull-up resisters are connected.I am trying to mount and read/writ...
TIM1 input cpature with DMA: DMA happens at high level when there is no rising edge. [F303K8T6]
Hi,i got some issue, where i restart a "5 times DMA" after i read the array. The first DMA is happening right after i startet it, when the level is high. But that is not a rising edge! I already made some test to verify this problem. The solution so ...
How to properly initialize LwIP for static IP or DHCP?
For example, my EEPROM has setting for static IP or DHCP.The problems is MX_LWIP_Init() does not have proper user code sections. It always call dhcp_start(), but I do not need it in case of static IP. The other problem is no any static IP config and ...
Resolved! STM32F722RE SPI bootloader weirdness (ack, mass erase)
I've got a design with a STM32F405RE bootloading onboard STM32F722RE via SPI1.I've implemented SPI bootloader host (mostly same as serial with addition of adding extra 5A frame and dummy reads in a couple places) and individually verified commands li...
Why are there identical functions like "HAL_TIM_IC_Init" and "HAL_TIM_Base_Init" ?
These functions above are are functional identical. And they are calling weak functions "(Base/IC)_MspInitCallback" and "HAL_TIM_(Base/IC)_MspInit". "HAL_TIM_Base_Init" is actually used in my generated code and the weak function is actually replaced ...
