Hi to all,I am not sure this is the correct forum, but I do not know where to put the question elsewhere.I need to interface with an SD card using SPI interface and I'm experiencing a big issue in write operation (CMD 24) because things quite always ...
In STM32H7x5 series, the MCU has 2 System Memory banks. Bank 1 is clearly described in reference manual, but not bank 2. My question is:What is the role of bank 2?Can user use bank 2 to flash homebrew bootloader?How to boot to bank 2?
Hi,My requirement is to use encoder mode of a Timer for driving pump. And using same Timer to drive the speaker. Timer 1 channel 1 would be used for Pump and Timer 1 channel 2 would be used for speaker. Timer 1 DMA is used to output sequence of pulse...
My project use STM32F030K6T6's ADC as AC 230v energy meter then upload to my website's server via ESP-07S. Now my design use HLK-PM01 AC-DC 5v and AMS1117 3.3v to power both STM32 and ESP-07S. Folllow AN2834 each VDD add 100nF ceramic cap + 4.7mF tan...
Hello everyone,For the first time now I need to write some data to the flash memory so it doesn't get lost when the board is turned off.I am using STM32F476-DISCO board. From the data sheet, I see that the main memory block contains 8 different secti...
WHICH ONE IS BEST?i have seen three methods:1, in_floating http://www.micromouseonline.com/2009/12/31/stm32-usart-basics/2, GPIO_MODE_AF_OD https://visualgdb.com/tutorials/arm/stm32/uart/hal/3, GPIO_MODE_AF_PP
On a NUCLEO-H743ZI board, I am using ADC3 configured like so:16-bit mode 6 MHz ADC clock8.5 cycles sampling timeTriggered by TIM3 to scan 4 channels every 10us BDMA puts the results into a memory bufferThe problem I have is that for a given voltage, ...
How to read 11 channels of ADC in STM32G070CB? I can read 8 channels through ranks 1 through 8, but I need to read 11 channels. What is the best way to do this reading?
i have enable three usarts, USART1 AND usart2 enabled tx rx idle. usart3 is just output logif i set SCB_AIRCR = (0x05FA0000 | 0x500); // group 2 ,(*(volatile uint8_t*)0xE000E425) = 0x00; // usart1 IPR// set a low priority// NVIC_IPR9 usart2 (*(volati...
I am currently using STM32f429I. I want to check the value read using SPI by connecting UART. However, when checking the manual (DS9405, 38P), it is indicated that other UART(USART1,2,3,6) can not be used except for UART4, 5, 7, 8 when using SPI as m...
