Posted on March 12, 2014 at 12:04Hello everybody! Yesterday I upgrade my stm32f4 discovery st-link v2 firmware. After that the coocox give error at erase flash. I have another board with old firmware, this is working well. What can I do this sutiati...
Posted on March 03, 2014 at 17:40Hello everybody. I am developing some test firmwares on a STM32F103 based board. After some working programs using the sleep mode, now I need to do some experience with the much more powerful standby mode. I need to ...
Posted on February 06, 2014 at 11:54I am using IAR with STM32-Value line discovery board. I am trying to program the kit but not getting programmed giving error like below, Fatal error: ST-Link DLL not found Session aborted! Can any one guide me ...
Posted on March 11, 2014 at 19:18Hello,I am using the STM32F303 with SPI1 in slave mode and no data packing. I am seeing an issue where I will get an interrupt when a byte is received, but the status register says that there is nothing in the recei...
Posted on March 11, 2014 at 21:48I'd like to model if it's practical to drive an STM32 output into a transistor. I've got some Optimos 3 transistors with a 2.8v Vth:http://www.mouser.com/ds/2/196/BSC340N08NS3G_rev2.6-76670.pdfThe transistor would b...
Posted on March 11, 2014 at 02:34LD8 LED is ON (USB over-current) regardless to program. Furthermore receiving data by UART3 using pin PC11 is impossible, but with PD9 works fine. Earlier I had no problems, and now after connected the board to the c...
Posted on March 11, 2014 at 16:50Hello everybody,I'am trying to use analog watchdog on STM32F051K4 and I face some problems. I want to measure a pulse on PA0 (ADC_IN0) of 100us wide with an 1V amplitude above 0.5V offset. There is no example on this...
Posted on March 11, 2014 at 08:52HelloI am trying to configure a timer to get interruption at 12 MHz on the STM32F429 Discovery Kit.I am currently using TIM2 and I cannot reach more than 2.25 MHzTheoritically I could reach 45MHz right?Thank you for ...
Posted on March 11, 2014 at 02:30I plan to make a inverter by using STM32 CPU. STEVAL-ISV003V1 is a good example. But I need to get its firmware.How can I get it? or I can only get it by buying this board?
Posted on March 11, 2014 at 00:54 For my project, I am doing audio mixing from three inputs (pins PC1, PC2, PC4 over Channel 11, 12, 14, respectively) and outputting it the external DAC on the F4-Discovery board. The mixing seems to work properl...
