If I understand correctly the STM32F7 USART/UART doesn't have a hardware FIFO implemented. So how do I prevent data corruption if the interrupt aren't handled in time? Timing is now critical.I see there a couple of examples which use DMA. Only how to...
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
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...
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.
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...
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 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...
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 ...
