Posted on June 05, 2014 at 16:16Hi,I am currently working on an application that will send/receive time and date data through serial connection via UART. To get a prototype up and running, I modified the RTC calendar example code that comes with STM...
Posted on June 06, 2014 at 05:13 Hi , I came across the following codes . TIM_TimeBaseInitTypeDef TIM_TimeBaseStructure; TIM_TimeBaseStructure.TIM_Period = 0xffff; TIM_TimeBaseStructure.TIM_Prescaler = 0; TIM_TimeBaseStructure....

Posted on June 06, 2014 at 07:36Hello, I am designing a board using STM32F030F4P6. I have to use STM32F0 Discovery board STLINK for ISP. Checking the schematics of Discovery board, I found out that the ISP connector (SWD) is connected as follows: 1....
Posted on June 05, 2014 at 14:47Hi, i'm using a fpga to control ov5642 camera. I've managed to get access to the registers by i2c protocol and set some of their values:register value0x3017 0x7f0x3018 0xfcwi...
Posted on April 09, 2014 at 11:33Hello All,I have read from STM324xx data sheet that the RTC is registers are still valid and running when Vdd is off and Vbat is present. I am not sure how the microcontroller manges normal running mode and standby m...
Posted on June 05, 2014 at 12:07The DMA for stm32F4 series has some advanced functions, could I ask for clarification here? Concurrent stream: Can two streams transmit data at the same time? Since one byte transfer is allowed. If the bus width is...
Posted on June 03, 2014 at 04:42Edit: My goodness the ST is user friendly as always, paste this article into a text editor or something to view. It ate my first submission and I have to write allover in MS word again. Now it had ate all my line feed...
Posted on June 06, 2014 at 00:52Hey ST Forum,I'm using the ST32F4-Discovery Board, and ran into some problems while testing UART4_TX in DMA Mode. When I look at oscilloscope, the TX line is pulled down, then gradually goes back to 3V. I think my Per...
Posted on July 11, 2011 at 15:01I'm an absolutly beginner in microcontrollers. I want to create a simple square wave signal on STM32F103VB with tim3, ch2, but nothing happens. Can anybody tell me what I'm doing wrong? Thanks Tom #define DEF_SPEED ...
