I can not read correctly 512 bytes or more. but 256 bytes read is correct.if i read 1024 byte read , my first byte and byte 512 is not correct

How to move interrupt vector from FLASH to RAM when using STM32F427?

Hi, I developed boot loader on STM32F427. When I try to erase FLASH, that will trigger HW watch dog(tick by interrupt timer) to reset our develop board. I search solution by google, many people say should move interrupt vector and IRQ handler progr...

I wonder if your BLE modules are suitable for the implants. And if they are so, how can it be packaged to work properly within the tissues?

Actually, I don't know if I have asked in the right section or not. But, if anyone can help with that, I will be very grateful.Thanks.

spi

Hi,I have problem with SPI data transfer on stm32h743VIH. Spi is used with external ADC. ADC data ready voltage level seems OK ~1,8 V (Vdd) but the MISO line shows only about half of this ~0,9 V. This seems to be too low for data transfer. MISO line...

writing serial data out for a nucleo f031K6

I recently bought a nucleo board for a project im making. I have in the past used 8 bit AVR chips but I want to step up to STM32. My project is some switches, leds, a DAC and an ADC. One thing that is common to all these elements is a serial data out...

I'm using ST_1.3.0 IDE. I cannot upload the factory released Demonstration after having successfully uploaded the Audio_playback_and_record demos. I am using STM32F4_Ddescovery_FW_V1.1.0. Thank you.

stm32F7 LL_drivers acknowledge interrupts

I combined 2 examples. USART3 I/O and SYSTICKS timer.When I receive a USART interrupt the Systicks stops working. There is a endless loop of interrupt calls of USART3. So I assume I didn't acknowledge the interrupt correctly. Only can't also find it...

What is the maximum value of LPUART baudrate ?

Hi, I am using STM32L071 which has Low Power UART (LPUART) Communication. I want to try LPUART at the maximum baudrate, but what is the maximum value of LPUART baudrate ? is it the same as UART in generally ? based on datasheet, the maximum baudrate ...

Any one have Samples source code for CUSTOM UART code based on STM32L152VB ?

UART - Sending data from UART2 and receiving data at UART1.

Hi, I have some problem with UART. im using stm32l152Vb uC... in that, im suing standard peripheral library...I configured two uarts (UART1 and UART2) both of them are working in normal mode. I want to send data from PC to mcu-UART2 and after receivi...
