Posted on July 25, 2012 at 01:46Hi, I am cery confuse about how to set DMA parameters. I would like to capture images from camera using DCMI module. I don't understand Burst and BufferSize params of DMA. I would like to capture QCIF (176x14...
Posted on July 22, 2012 at 12:21I have been building my own Boards. And have experience with an assortment of Micros. WARNING #1 : I have found that these STM Chips are Very SENSITIVE to Voltages. I accidentally tied the USB 5V source to the VDD Bus...
Posted on July 24, 2012 at 19:04General Purpose Timer 4 counts the position from incremental encoder in quadratur mode. The Encoder has 200 slots and for low speeds, the frequency is rather low. To derive the rotation speed, I subtract 2 positions i...
Posted on March 07, 2012 at 15:22I configure SPI2 and I2S2_ext for running I2S in fullduplex mode using DMA1_Stream4 and DMA1_Stream2. DMA1_Stream4_IRQHandler called and i2s tx is working fine, but DMA1_Stream2_IRQHandler not called at all. Please ...
Posted on July 16, 2012 at 18:06Hi all!!!Please help me. A have problem with I2S interface in this MC. I need to work with audio codec cs4221 by means of I2S. I setup I2S2 interface in full-duplex mode (I2S2- Master reciev, I2S2ext - Slave TX). Data...
Posted on July 16, 2012 at 11:22Hi, I am new to LCD display controller. I am using Olimex STM32F207 board with onboard 6610 LCD color 128x128 TFT display. I have initialized the LCD according to Example code. I my case I could see LCD backlight is ...
Posted on July 22, 2012 at 03:26Greetings, I have a small number of bytes (less than 80 bytes) that I need to store in persistent storage, but the values may change in excess of 10,000 times. I believe the SRAM would work fine for this, but I would...
Posted on July 24, 2012 at 00:31I am using a STM32F103 that has implemented a USB device stack based on the Joystick Mouse HID demo code from STM. My app is able to go into USB selective suspend and to resume successfully, both from host-initiated ...
Posted on July 02, 2012 at 15:01Hi, I am using IWDG and it works good. I would like to stop it when core halts (in breakpoints), therefore i did: DBGMCU->CR |= DBGMCU_CR_DBG_IWDG_STOP; But it does not stop the IWDG. Do i miss something? Thanks.
Posted on July 17, 2012 at 05:01Hi, I originally was planning on using the Discovery demo board, but have since changed to placing the MCU directly on my PCB. Now what is the easiest way to program the thing? The Discovery uses a STM32F103C8T6, per...
