Posted on January 22, 2015 at 19:46Now that I've got my USART working with my DMA to do two 8-bit transfers per 16-bit word, I have encountered another problem: incorrect data. I know the mantra for serial comms when data is wrong is baud rate, baud...
Posted on January 23, 2015 at 04:52@ali.babarDid you manage to get any further with this high bandwidth DCMI > SDIO concept? I am looking to achieve similar (without external memory). It would be handy to know what type of throughput you managed to ...
Posted on January 22, 2015 at 10:07 Hi, I am trying to receive RF packet using USART1 IRQ, using below code. But packets are missing in the receive end. My point here is sometimes i will receive packets and the received packet is completely...
Posted on January 23, 2015 at 01:27An application which includes DMA over SPI communication protocol is running nicely once STM32F405 is powered up. However, once running the same code from debugger - it does NOT behave properly. What might be the c...
Posted on January 22, 2015 at 06:55ST32F415 to be exact. Boot ROM disabled by BOOT0 jumper. I saw a product where a custom bootloader was flashed into sector 11 (highest in that chip). And a reset vectors to that bootloader. User code goes in sector...
Posted on January 22, 2015 at 21:29Anyone care to confirm that the LSM303DLHC acc/mag chip is mounted back-to-front on the f3discovery board with respect to the N(orth) silkscreen legend? Thanks folks, Colin #f3discovery-board
Posted on January 20, 2015 at 00:39 Hi, I'm trying to use a mass storage example taken from here http://www.st.com/web/catalog/tools/FM147/CL1794/SC961/SS1743/LN1734/PF258157. When I'm executing, at startup the driver gets a S...
Posted on January 18, 2015 at 20:43 Hi, I am using stm32f4 's timer 1 in pwm mode.I configured the board frequency using the excell clock configuration tool. I managed to provide TIM1 a clock source of 8 MHZ. Then i put 20 in timer 1 's pr...
Posted on January 22, 2015 at 19:39I just modified the LTDC example for the discovery and generated my own (smaller) image that fits under the size limit.The image, however, should be gold, yet it is blue! It is an RGB565 image I made with the segg...
Posted on January 06, 2015 at 20:19I've got a project with three ASICs that expect 16-bit words to be received via SPI, transferred via DMA . Unfortunately, due to a pin conflict, I only have SPIs 1 and 3 available. So. I was thinking about trying t...
