Hello, I'm testing the STM3240G-eval with the USB host MTP. The goal is to retrieve the photo from a canon EOS 100.The camera uses PTP protocol.As the demonstration code read .wav file, I wrote a wav file to the root of the SD card. The digital came...
The current system is configured as shown in the figure above, and the serial communication is using RS485.In the system configuration, UART3 and UART2 are used, and the message from the PC through UART3 is delivered to the device through UART2 from ...
Hello -> We are using a custom board with STM32H745 controller and 8GB eMMC communicated with sdmmc. -> getting SDMMC_FLAG_TXUNDERR bit after writing 64 bytes to eMMC. But i am giving 1k buffer array to write. -> eMMC initialization, reading logic bl...
So I have a abstracted function to read the INA226 component. The function reads the data completely fine over I2C. The problem occurs when I try to display the read data on my dev terminal (Terra Term) over the COM port for STM32. The output on the ...
What exactly is meant by "If Boot from FLASH"?
I'm learning STM32 with the board above and trying to program the ADC conversion.However, when i start debug with keilC and observe the Adc value, nothing happen.I check the ADC register and realized the SWSTART can not be set to start conversion ...
Hello, I am trying to create a simple frequency measuring device using 1 optical encoder and NUCLEO-F401RE board. I want to capture frequency (or period) of impulse, so I was thinking to use input capture mode and capture rising edge of impulses and ...
Dear all,I'm new to this forum, so apologies if I post this in the wrong category. I'm trying to find a way to implement a deadtime compensation mechanism using a STM32G4. I have a 3-level 3-phase VSI. The switching frequency is 50kHz, the deadtime i...
Trying out a simple timer w/ interruptI am using the below code to enable interrupt However during debug when ever I go to NVIC_SetVector(....)orTIM4->CR1 |= TIM_CR1_CEN; ;//-> CEN=1;//Start Timer4 I get an error'Break at address "0x80009b0" with no ...
Hi.I am using SDMMC1-eMMC(16GB), SDMMC2-SD Card connected on a custom board.Both eMMCs and SD-Cards use FatFS as their file system.Both work fine when used alone.However, if you use f_open or f_write on FatFS on eMMC, you sometimes get an error and t...
