Posted on June 19, 2015 at 13:56hi ,now i am working with camera interface with stm32f40IG controller.already i capture the image by using OV9655 camera which code and hardware are provide by STM.the sample code is for just capturing the images and...
Posted on June 19, 2015 at 17:44Hello I have a problem with the vector table relocating, I moved the vector table with the following code, but when I am activating the usart interrupts the programs hangs#define APPLICATION_ADDRESS (uint32_t)0x08...
Posted on June 18, 2015 at 07:32I am using STM32F101 microcontroller. Is it necessary to disable the receive interrupt in order to transmit something through UART? My reception priority is high, so is it okay to keep the receive interrupt enabled wh...
Posted on June 18, 2015 at 15:25I have the STM32F105 RTC alarm working correctly internal to the chip, but I cannot get the alarm to control pin PC13.I have the BKP register configured to set the alarm output BKP_RTCOutputConfig(BKP_RTCOutput...
Posted on June 19, 2015 at 15:18I am using F429 in my project. The USB FS is required 168Mhz clocking, but the I2C need 180MHz in order to use 400khz speed. When I set the clocking to 168MHz and set the I2C speed to 100khz, the I2C always stop after...
Posted on June 19, 2015 at 01:48I'm working with a device that uses the SMB Address Resolution Protocol as part of the response to generating an internal alert. I have no difficulty reading and writing address registers in general (With the peripher...
Posted on May 11, 2015 at 05:18Dear sir: I use STM32F407 discovery board's ST-link feature to communicate with my custom STM32F427 board. I can download (and reset/run) the execution file created by uVision 5.0.5 via ST-link utility tool. However uV...
Posted on June 19, 2015 at 13:27Hello, what is a sensible relation between the GPIO speed setting and peripheral device speed? E.g. OSPEED = 00 on a >2.7 Volt STM32F42x with 10 pF load has a value of 8 MHz max. Is that good for a SPI clock rate of 8...
Posted on June 06, 2015 at 15:17HelloThere is some mismatch between recommended power supply scheme of stm32f407(page 76 of stm32f407 datasheet, Rev5) and what is implemented in stm32f4discovery.It would be good to be explained by someone from ST.
Posted on June 18, 2015 at 13:29Hello everybody,I use a SD card (SDIO). - When the SD card is inserted but not mounted, my analog inputs convert voltages with a very good precision.- When I mount the SD card, my analog inputs starts to convert volta...
