The HAL Manual for the STM32G070xx mentions OB_WRPAREA_ZONE_A and OB_WRPAREA_ZONE_B. The Reference Manual mentions Zone A and Zone B. But there is no mention of the difference between the two or when to use one vs the other. There are 64 pages of Fla...
Hi,I am trying to receive voltage from an external ADC, MCP3421 using I2C. These values are then transmitted over USART to be viewed by the user ranging from (-2.048 to 2.048). The MCU I am using is STM32F051K8.The problem that I am facing is that th...
Use STM32F405's SPI + DMA as a slave, circular mode, DMA 16bytes interrupt, but every time send 16bytes to master, the first byte is always the byte that last frame's last byte , it looks like spi tx register is not clear, always contain the last by...
Hello I'm using a STM32F769 discovery board. I was trying to use timer2channel2 to trigger the ADC conversion. I am setting registers manually and wanted to turn on event generation on channel 2 match. TIM2->EGR |= TIM_EGR_CC2G_Msk;However when I ran...
Hi,i'm trying to blink only one led. I have a problem with one of four leds. Because as you in my code, i'm trying to blink only 'green led'. But 'blue led' blinks also. #include "stm32f4xx.h" // Device header #include "stm32f4xx_hal...
we are going to use STM32F417VG for our new developemntKindly specifiy thge life cycle of the controller
Hello, I wanted to upgrade my simple blinky program with the usart 2, so that it sends a simple 'B' over the serial port to my PC. I am using a Nucleo-F334R8. In the datasheet it says usart2 is connected with the USB port.Here is my code, that is not...
In the 'L053 DS, DS10152 Rev 9 , pin PB5 is marked as TIM22_CH2 both in Table 15. STM32L053x6/8 pin definitions and Table 17. Alternate function port B . However, this is an exceptional pin which can be remapped to TIM3_CH2. The DS in both tables sho...
Hi , I am trying to flash my code of GPIO toggle into the STM32H745 Disco board,but it is giving the error .While building the project I have seen an error "GPIO_CM4\GPIO_CM4.sct(7): error: L6235E: More than one section matches selector - cannot all...
Posted on July 03, 2016 at 10:49Hello,I generated the code using the STM32CubeMx.I'm trying to I2C communication between STM32F4(master) and IC(slave, 7bit address).I tested to two functions for I2C communication.HAL_I2C_Mem_Write is OK, but HAL_I2C...
