Posted on April 12, 2014 at 13:26I am using STM32F103 and its Referrence Manual(RM0008) said that TIM1_DMAR's default value is 0. BUT when I connected the hardware and debugging with JLink, I found that TIM1_DMAR is always 1. And I never set it.AND ...
Posted on April 13, 2014 at 13:32Hi All, please could you help me to implement ADC converter using FSMC interface ? A/D converter is 16bit and i need high speeds for transfer ... at least 20-30 MSPS i would like to know which pins to connect ... ...
Posted on April 14, 2014 at 02:41Guys, Can I use STM32F103VET6 with SDcard and uClinux? I put linux on SDcard and use internal RAM or I put linux on NAND flash ? Do I need external RAM ? Any ideas on doing that ? Thanks
Posted on April 12, 2014 at 17:43Hi everyone,I have problem with writing to flash memory in my application. uC STM32F051C4Code:#define FLASH1 (*((uint32_t *)0x08001016))then flash function:void FLASHunlock(void){ if (FLASH->CR &0x00000080) { FLASH->...
Posted on April 11, 2014 at 12:38Special Thanks to Mr. Clive. Your replies are of great help to me.Now the problem has been almost almost solved. There used to be near 900ms of vacant of pulses, and Now the pulses are almost continuous. The stepper ...
Posted on April 12, 2014 at 05:54I have generated a project containing Ethernet and FreeROTS use STM32CubeMx tool on open407 or open429 but it does not work ;In addition,i use STM32Cube_FW_F4_V1.1.0\Projects\STM324x9I_EVAL\Applications\LwIP\LwIP_HTT...
Posted on April 13, 2014 at 03:03I got several lines of code in TIM1_CC_IRQHandler and need to know its exact running time because some real-time requirements.So when I run simulation I got a time span between the entrance and the exit of the ISR. I...
Posted on April 11, 2014 at 18:27In my programm I use uart4 with 115200 baud. I want to receive data from devices - so I configure UART in RxMode. I enebled only one interrupt source for itUSART_ITConfig(UART4, USART_IT_RXNE, ENABLE); My interrupt ...
Posted on April 12, 2014 at 08:14 Guys, Why can't I use 50MHz for SDIO ? GPIO_InitStructure.GPIO_Speed = GPIO_Speed_50MHz; it worked only with 10MHz GPIO_InitStructure.GPIO_Speed = GPIO_Speed_10MHz; 1. /*!< Co...
Posted on April 11, 2014 at 15:27I wonder how to read all port simultaneously such as GPIOA0 up to GPIOA7 or the equivalent of arduino codes DDRA = B00000000; // sets Arduino Mega Digital pins 22(PORTA0) to 29(PORTA7) as inputs allBus = PINA; //re...
