I've spent literally dozens of hours just trying to understand and get a timer to work. This is not due to a lack of effort.I'm creating a setup to use TIM1 in input capture mode to capture the rising and falling edges of a pin coming from an IR rece...
Hello I am trying to communicate with TI BQ28Z610 by using Nucleo-F746ZG. All I do is trying to read data from TI chip. I am sending 0x08 to slave address 0x16.I2C frequency is 80kHz and pull ups are 10 K. Here is the related part of the trial code:w...
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...
